WARNING

Equipment Hazard!

Rotating shafts and electrical equipment can be hazardous. Therefore, it is strongly recommended that all electrical work conform to National Electrical Code (NEC) and all local regulations. Installation, start-up and maintenance should be performed only by qualified personnel. Failure to follow the NEC or local regulations could result in death or serious injury.

Factory recommended procedures, included in this manual, should be followed. Always disconnect electrical power before working on the unit.

Although shaft couplings or belt drives are generally not furnished by the manufacturer, rotating shafts, couplings and belts must be protected with securely mounted metal guards that are of sufficient thickness to provide protection against flying particles such as keys, bolts and coupling parts. Even when the motor is stopped, it should be considered alive as long as its controller is energized. Automatic circuits may start the motor at any time. Keep hands away from the output shaft until the motor has completely stopped and power is disconnected from the controller.

Motor control equipment and electronic controls are connected to hazardous line voltages. When servicing drives and electronic controls, there will be exposed components at or above line potential. Extreme care should be taken to protect against shock. Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with another person in case of an emergency. Disconnect power whenever possible to check controls or to perform maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electric control or rotating equipment.

Safety Guidelines

1. The drive must be disconnected from the AC line before any service work is done.

2. The STOP/OFF key on the local control panel of the drive does not disconnect the equipment from the AC line and is not to be used as a safety switch.

3. Correct protective grounding of the equipment must be established. The user must be protected against supply voltage and the motor must be protected against overload in accordance with applicable national and local regulations.

4. Ground currents are higher than 3 mA.

Warnings Against Unintended Start

1. While the drive is connected to the AC line, the motor can be brought to a stop by means of external switch closures, serial bus commands or references. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stops are not sufficient.

2. During programming of parameters, the motor may start. Be certain that no one is in the area of the motor or driven equipment when changing parameters.

3. A motor that has been stopped may start unexpectedly if faults occur in the electronics of the drive, or if an overload, a fault in the supply AC line or a fault in the motor connection or other fault clears.

4. If the LOCAL/HAND key is activated, the motor can only be brought to a stop by means of the STOP/OFF key or an external safety interlock.

Motor Overload Protection

NOTE Person installing drive is responsible to provide proper grounding and branch circuit protection for incoming power and motor overload according to National Electrical Code (NEC) and local codes.

WARNING

Hazardous Voltage!

Touching electrical parts may be fatal, even after equipment has been disconnected from the AC input line. To be sure that capacitors have fully discharged, wait 14 minutes for 208 V and 480 V units and 30 minutes for 600 V units over 25 hp after power has been removed before touching any internal component. Failure to wait for capacitors to fully discharge before touching internal components could result in death or serious injury.

The electronic thermal relay (ETR) in UL listed TR1s provides Class 20 motor overload protection in accordance with the NEC in single motor applications when parameter 117 is set for ETR TRIP and parameter 105 is set for the rated motor current.

General

The specific installation instructions may vary depending upon the model of TR1 Series VFD being installed. When this occurs, the model can be identified by a TR1 Type 6XXX number. This number can be found on the red nameplate on the outside left side of the drive enclosure, or the outside right side of a drive with an auxiliary enclosure.

The drive must always be installed vertically. To ensure that no injury or damage occurs, the drive must always be firmly attached to the wall or the floor before further installation work is carried out.

Clearances

The drive is cooled by air circulation. For proper cooling, the minimum distances above and below the unit must be maintained as shown in the table below. For units in an auxiliary enclosure with the drive mounted on a backpanel, the required clearances are measured from the top and bottom of the drive, not the backpanel.

Backplate Requirements

Mount directly to the wall all drives without a backplate. This ensures that air flow is in contact with the heatsink all the way from the bottom of the drive. If this is not possible, a metal plate at least as large as the back of the drive may need to be firmly mounted to the back of the drive (see tables below). A backplate assembly is available from Trane.

8" (200mm) 8" (200mm)

9" (225mm) 9" (225mm)

All drives can be mounted with no side clearance. Sufficient space must be provided in front of the drive for door swing on units with a hinged door. TR1 drives 350 hp and above require 25 inches (605 mm) front space for access. In addition, sufficient room must be available for installation and service access. On units with an auxiliary enclosure, the auxiliary enclosure door will have a greater door swing than the drive. See the dimensional drawings of the auxiliary enclosure which are included with the drive.

Drives without a backplate must be mounted directly to a solid wall with no spacers between the drive and the wall. Free-standing drives without a backplate require a backplate to be mounted.

Plenum Mounting

The drive is UL rated for plenum mounting as well as auxiliary panels that may be supplied with the drive. If the equipment is to be mounted in the plenum, allow sufficient access for servicing. All normal clearance, temperature, humidity limitations and local codes apply.

Standard Service Conditions

The mechanical and electrical components of the TR1 Series VFDs can be adversely affected by the environment. High temperatures and harsh environments may reduce life of drive if proper precautions are not taken.

Grounding Plate

Drives up to 3 hp, 200 to 240 V, and up to 10 hp, 380 to 460 V and 550 to 600 V with a NEMA 1 enclosure have a plastic bottom cover with provision for conduit entry. To meet UL requirements, the metal grounding plate must be in place above the plastic bottom cover. The plate must be grounded to the chassis and the conduit grounded to the plate. If the grounding plate is not factory installed, it must be installed in the drives that have a plastic bottom panel to ensure proper grounding of the conduit to the enclosure. Connect the ground wire from the grounding plate to the ground tab marked with the ground symbol.

This tab is located near the AC line terminal strip. Mount the bottom cover on the control unit.

Shielded Wires

Wires to control signals should be shielded to reduce radiofrequency noise interference. When RFI is a concern, shielded cable should be used between the drive and the motor.

If unshielded control wires are used, control inputs are subject to signal disturbances. Such disturbances may affect drive operation. Extreme noise levels may disturb the microprocessor of the control card.

The shield of the control wires must be grounded at the cable clamp at the bottom of the drive, but the shield must continue with the cable all the way up to the control card. The shield is not to be connected to any of the terminals on the control card. For safety reasons, the insulation around the shield should only be removed where it is connected to the cable clamp. The insulation should be left on the shield between the clamp and the terminals.

Airborne Liquids

Rain, steam, oil, water vapor, high humidity, and such may cause corrosion of drive components. In such environments, use NEMA 12 enclosures. NEMA 12 enclosures limit the exchange of outside air into the drive enclosure. Extremely harsh environments may require a higher levels of protection.

Solids

Dust, dirt, metal drill shavings, foreign objects and the like may cause mechanical, electrical or thermal failure in the drive. A NEMA 1 enclosure provides a reasonable degree of protection against falling particles but will not prevent the drive fan from pulling dirty air into the drive. A typical indicator of excessive levels of airborne particles is dust around the fan. In dusty environments, use NEMA 12 enclosures.

Corrosive Chemicals

In environments with high temperatures and humidity, corrosive gases such as sulfur, nitrogen and chlorine compounds cause corrosion to occur in the drive. Such chemical reactions rapidly affect and damage electronic components. An indication of corrosion is blackened copper or oxygenation of steel or aluminum. In such environments, it is recommended that the equipment be mounted in a cabinet with fresh air ventilation and that corrosive compounds be kept away from the drive. A non-ventilated cabinet fitted with an air conditioner as a heat exchanger may be used. Conformal coated circuit boards may be specified to reduce the corrosive effects of a harsh environment.

Maximum Relative Humidity

Generally speaking, all conductors coming from a shieldedcontrol cable must be as short as possible. Long conductor ends attract noise. The shield must be connected to the chassis by means of the cable clamp. Long pigtails on the shield reduce the effectiveness of the shield.

CAUTION

Drive Failure!

Do not connect input power to drive output motor terminals. Connecting input power to motor terminals will result in drive failure when power is applied.

On drives with an auxiliary enclosure, some or all of the power connections at the drive will be factory made. Custom input and output terminals may be inside the auxiliary enclosure. See the drawings supplied with the drive for details on custom terminal blocks and conduit entry locations for the auxiliary enclosure.

Input Power Delay

To ensure that the input surge suppression circuitry performs correctly, a time delay between successive applications of input power must be observed.

The table below shows the minimum time that must be allowed between applications of input power.

Input voltage 380 V 415 V 460 V 600 V W aiting time 48 sec 65 s ec 89 sec 133 sec

Power Connections

1. Make all power connections with 75o C rated copper wiring.

2. Conduit entry must be from the bottom on all drives. Conduit entries are provided on smaller drives. For drives with auxiliary enclosures, refer to the dimensional drawings provided for conduit entry locations.

3. To meet UL requirements, install the metalgrounding plate in all drives that have a plastic bottom. Install the grounding plate just above the plastic bottom. Ground the metal plate to the chassis and ground the conduit to the metal plate.

4. The conduit entries provide strain relief for the wires in drives mounted in NEMA 1 or NEMA 12 enclosures. With chassis mounted drives, the power and control wires must have strain relief supplied by the installer. D provide strain relief.

NOTE

Run input power, motor wiring and control wiring in three separate metallic conduits or raceways for high frequency noise isolation. Failure to isolate power, motor and control wiring could result in less than optimum drive and associated equipment performance.

WARNING

Grounding Hazard! For operator safety, it is important to ground drive properly. Follow the grounding guidelines provided. Failure to follow grounding guidlines could result in death or serious injury.

Input Power Connection

For drives with no auxiliary enclosure, connect input power to drive terminals L1, L2, and L3, (terminal numbers 91, 92, and 93). If an auxiliary enclosure is provided, input power connections are made in the auxiliary enclosure. Refer to the connection diagrams shipped with the drive.

Size wiring to the input current of the drive as shown in the tables below. Maximum AWG wire size is also provided. Local codes must be complied with for cable sizes.

Motor Wiring Connection

For drives with no auxiliary enclosure, connect the motor to drive terminals U, V, and W (terminal numbers 96, 97, and 98). Terminal 99 is earth ground. If an auxiliary enclosure is provided, refer to the connection diagrams shipped with the drive. Ground the shield on the motor wire, if used, at both the drive and the motor.

Grounding

Ground the drive properly. Use a ground wire at least 7 AWG (10mm2). Connect the ground wire directly to a reliable earth ground. Do not use the conduit connecting to the drive as a replacement for a ground wire. Do not ground one drive to another in a daisy chain fashion.

Electronic Thermal Protection

The electronicthermal relay is UL approved for single motor thermal protection as long as the following is complied with:

1. Parameter 117, Thermal Protection, is set to ETR TRIP.

2. Parameter 105, Motor Current, is set for the full-load nameplate motor current.

Page 17

Multiple Motors

The TR1 can control several motors at once, all changing speed together. The sum of the nameplate currents of all the motors must not exceed the current rating of the drive.

External DC Bus Connection

Terminals 88 and 89 access the DC bus of the drive. They can provide DC backup power for the drive or to connect to a 12-pulse input rectifier.

CAUTION

Motor Damage!

When multiple motors are used, the drive electronic thermal relay cannot be used to provide individual motor protection. A separate motor overload must be supplied for each motor. Failure to provide individual motor protection when multiple motors are used could result in motor or equipment damage.

If the multiple motors are of significantly different sizes, starting problems may occur. This is because the higher electrical resistance of smaller motors will require more start voltage than larger motors.

NOTE Automatic†Motor Adaptation and Automatic Energy Optimization cannot be used for multiple motor installations.

WARNING

Hazardous Voltage!

Terminals 88 and 89 will be at approximately 150% of line voltage and remain at high voltage for up to 30 minutes after power has been removed from the drive. To be sure that capacitors have fully discharged, wait 14 minutes for 208 V and 480 V units and 30 minutes for 600 V units after power has been removed before touching terminals 88 and 89. Failure to wait for capacitors to fully discharge before touching DC bus terminals could result in death or serious injury.

CAUTION

Equipment Damage!

Do not connect anything to terminals 88 and 89 without first consulting with Trane. Failure consult with Trane could result in motor or equipment damage.

Control Connections

All terminals for the low voltage control wires are located under the protective cover below the keypad. Remove the cover with a screwdriver or other pointed object as shown bellow.

Drive Inputs and Outputs

The drive operates by receiving control signals. Control input gets to the drive in three possible ways. One way is from input signals through the wiring connected to the drive control terminals. The drive control terminals are located below the LCP keypad.

Another control source is through serial communication from a serial bus. A serial communication protocol supplies commands and references to the drive and reads status and data from the drive. The serial bus connects to the drive through the RS-485 serial port. Use of serial communication may require installation of a corresponding option card.

A building management system, remote sensors, a speed command from associated equipment, or a PLC (programmable logic controller) are examples of possible remote drive controllers.

The third way for drive control input is through the keypad on the front of the drive when operating in local (hand) mode. These inputs include start, stop, reset, and speed reference.

Electrical Installation, Control Terminals

Torque control terminals to 5 in-lbs (0.5-0.6 N-m) Max. wire size: 16 AWG (1.5mm

The diagram below shows the location of the control terminals. The programming section of the manual covers the programmable terminals in greater depth.

)

Input Signals

The drive can receive two types of remote input signals: digital or analog. Digital inputs are wired to terminals 16, 17, 18, 19, 20 (common), 27, 29, 32, and 33. Analog inputs are wired to terminals 53, 54, and 55 (common), or terminal 60.

Analog signals can be either voltage (0 to +10 VDC) connected to terminals 53 and 54, or current (0 to 20 mA or 4 to 20 mA) connected to terminal 60. Analog signals can be varied like dialing a rheostat up and down. The drive can be programmed to increase or decrease output in relation to the amount of current or voltage. For example, a sensor may supply a variable current. The drive output, in turn, regulates the speed of the motor connected to the drive in response to that analog signal.

Digital signals are a simple binary 0 or 1 which, in effect, act as a switch. Digital signals are controlled by a 0 to 24 VDC signal. A voltage signal lower than 5 VDC is a logic 0. A voltage higher than 10 VDC is a logic 1. Zero is open, one is close. Digital inputs to the drive are switched commands such as start, stop, reverse, coast, reset, and so on. (Do not confuse these digital inputs with serial communication formats where digital bytes are grouped into communication words and protocols.)

The RS-485 serial communication connector is wired to terminals (+) 68 and (-) 69. Terminal 61 is common and may be used for terminating shields only when the control cable is run between VLT drives, not between drives and other devices.

Page 19

Output Signals

The drive also produces output signals that are carried through either the RS-485 serial bus or terminals 42 and 45. Output terminals 42 and 45 operate in the same manner as the inputs. These terminals can be programmed for either a variable analog signal in mA or a digital signal (0 or 1) in 24 VDC. In addition, the terminals can provide a pulse reference of 0 to 32,000 pulses. Output analog signals generally report the drive frequency, current, torque and so on to an external controller or system. Digital outputs can be control signals used to open or close a damper, for example, or send a start or stop command to auxiliary equipment.

Additional terminals are 01, 02, and 03, which are a Form C relay output. Terminals 04 and 05 are a 1 A low voltage relay output.

Terminals 12 and 13 provide 24 VDC low voltage power, often used to supply power to the digital input terminals (16-33). Those terminals must be supplied with power from either terminal 12 or 13, or from a customer supplied external 24 VDC power source. Improperly connected control wiring can be the cause of a motor not operating or the drive not responding to a remote input.

Programming Control Terminals

Control terminals must be programmed. Each terminal has specific functions it is capable of performing and a numbered parameter associated with it. See the table below for associated parameter numbers. The setting selected in the parameter enables the function of the terminal.

It is important to confirm that the control terminal is programmed for the correct function. See Control Panel for details on operator interface and changing parameters.

In addition, the input terminal must be receiving a signal. Confirm that the control and power sources are wired to the terminal. Then check the signal.

Control Terminal Functions

The following is a description of the functions of the control terminals. Many of these terminals have multiple functions determined by parameter settings.

Signals can be checked in two ways. Relay status can be selected in the display using the [DISPLAY MODE] key (see Display Modes), or a voltmeter may be used to check for voltage at the control terminal.

In summary, for proper drive functioning, the drive control terminals must be:

1. wired properly

2. programmed correctly for the intended function

3. powered

4. receiving a signal

NOTE

Electrical Installation, Control Wiring

Torque: 5 - 6 in-lbs Screw size: M3

Shielded control wires are recommended. To reduce interference from electrical noise, ground the cable shield at a cable clamp, as shown below, at both ends. Connect the shield to the grounded clamp. Very long control wires may create 60 Hz interference. To resolve this, connect one end of the shield to earth with a 0.1µF capacitor, keeping the leads as short as possible. If interference persists, disconnect the grounded shield connection at the end opposite to the drive.

DIP Switches 1 through 4

DIP switches are located on the control card.

They are used for serial communication and the common of digital inputs 16 through 33. The switch positions shown are the factory settings.

Sw itc h 1 i s no t used .

Switches 2 and 3 are used for terminating serial communication. On the first and last drive in a multiple device network, or on the only drive of a single drive network, switches 2 and 3 must be ON (the default setting). On all other drives in a multiple device network, set switches 2 and 3 to OFF.

Switch 4 separates the common for the internal 24 VDC supply from the common of the external 24 VDC supply. Normally this switch is ON and the power supply is present at terminals 12 and 13. Set Switch 4 to the OFF position when an external 24 VDC supply is used.

Ground Leakage Current

It is normal for there to be some leakage current from the drive to earth ground. Paths of current leakage are shown on the drawing below. The leakage current will exceed 3.5 mA.

Paths of Normal Current Leakage to Ground

Page 23

Galvanic Isolation

Galvanic isolation offers protection from electric shock. All control terminals of all TR1 drives, and terminals 1 through 3 of the relay output, offer galvanic isolation. The galvanic isolation in the TR1 conforms to the European standard EN 50178. (See figure below.)

The components that make up the galvanic isolation are:

1. Power supply, including signal isolation.

2. Gate drive for the IGBTs, the trigger transformers and optocouplers.

3. The output current Hall effect transducers.

Galvanic Isolation

Extra Safety Protection

Residual Current Device (RCD) relays for ground fault protection, or multiple protective grounding, can be used as extra safety protection, provided that local safety regulations are complied with. In case of a grounding fault, the fault current may contain a DC component. If RCD relays, also known as Earth Leakage Circuit Breakers (ELCB), are used, they may be suitable for protection of 3-phase equipment with a bridge rectifier and for a brief current surge at power-up.

Electrical Noise

In general, electrical noise can be divided into two forms: wire-borne electromagnetic interference (EMI), and radiating radio frequency interference (RFI).

Using shielded motor cables reduces RFI but increases EMI. This is because shielded wires have a greater capacitance than unshielded wires. Unshielded input power connections to the drive generate more noise in the radio frequency range on the AC line. The shield reduces the radiated noise, but increases the low-frequency electromagnetic noise on the AC line. But, since the noise current is taken back to the unit through the shield, only a small electromagnetic field is generated from shielded motor wires.

With an EMI filter, the noise level on the AC line will be reduced to about the same level for shielded and unshielded wires alike.

Connect the motor wiring shield, if used, in the enclosure of the drive as well as at the motor. Use shield brackets to avoid pigtail shield ends. Even short pigtails increase the shields impedance at higher frequencies, which reduces the shields effect and increases the noise produced.

It is generally easier and less complicated to use unshielded motor wires than shielded cables. If unshielded wires are used, the RFI will be greater. But, since the strength of the radiated signal decreases with distance from the signal source, radiated noise is generally not a problem.

To reduce the noise level from the total system (drive + installation) make the motor wiring as short as possible.

Provide separate conduits, or raceways, for power, motor and control wiring to provide the greatest immunity from distortion.

Since leakage current is greater than 3.5 mA, reinforced grounding must be provided if compliance with EN 50178 is required. The relays must be suitable to meet the following requirements:

1) protecting equipment with a DC content (Din VDE 0664) in the fault current (3-phase rectifier)

2) power-up with short pulse-shaped charging current to ground

3) high leakage currents

RCD fault relays type B comply with these requirements according to the norm IEC 755-2.

Application Control Connection Examples Two-wire Start/Stop

In Auto mode, closing the contact to terminal 18 will make the drive run. In any mode, opening the safety interlock contact to terminal 27 will stop the drive.

Set Parameter 302 to Start. Set Parameter 304 to Safety Interlock.

Digital Speed Up/down

Closing the switch to terminal 32 will make the drive accelerate. Closing the switch to terminal 33 will make the drive decelerate.

Run Permissive

After receiving a run command, the drive will apply power to the damper motor and wait until it receives permission via the switch that is connected to terminal 16.

Set Parameter 300 to Run Permissive. Set Parameter 302 to Start. Set Parameter 304 to External Fault. Set Parameter 323 to Start Signal Applied.

Two Feedback Signals

The drive processes two independent feedback signals during closed loop operation. It can respond to the sum, difference, average, minimum or maximum of these signals.

Set Parameter 306 to Speed up. Set Parameter 307 to Speed down. Set Parameter 305 to Freeze reference.

Potentiometer Reference

A manual potentiometer is used as a input reference for the drive.

Set Parameter 308, Terminal 53, Analog Input Voltage, to Reference. Set Parameter 309, Terminal 53, Min. Scaling, to 0 V. Set Parameter 310, Terminal 53, Max. Scaling, to 10 V.

Set Parameter 308 to Feedback. Set Parameter 311 to Feedback Set Parameter 417 for the desired operation.

Transmitter Connection

The drives internal 24 VDC power supply is used to power an external 4 to 20 mA transducer.

Set Parameter 314, Terminal 60, Analog Input Current, to correspond to the purpose of the 4 to 20mA signal. Set Parameter 315, Terminal 60, Min. Scaling, to 4 mA Set Parameter 316, Terminal 60, Max. Scaling, to 20mA.

Because the commons of the +24 VDC power supply and the input reference follower have separate circuit commons, it is necessary to connect a jumper between terminals 39 and 55.

Page 25

Control Panel

The Local Control Panel (LCP), normally mounted on the front of the drive, is a complete interface for programming and operating the drive. The control panel can be removed from the drive and installed up to 10 feet (3 meters) from the drive by using a remote mounting kit.

The control panel has five functions:

1. Display

2. Keys for changing the display

3. Keys for changing programming parameters

4. Indicator lamps

5. Keys for controlling drive operation

The LCP uses a four-line, alpha-numeric, back-lit, LCD display. The display can show four operating data values and three operating condition values continuously. During programming, all the information required for quick, effective parameter setup of the drive will be displayed. As a supplement to the display, there are three indicator lamps for power on (ON), warning (WARNING) and alarm (ALARM).

All drive parameters can be changed from the control panel, unless this ability has been locked out by setting parameter 016, Lock for Data Change, to Locked, or by a digital input to terminals 16 through 33. See the related parameters for more information.

Keys for Parameter Changes

The keys are divided into groups by function. The keys between the display and indicator lamps are used for parameter setup, selecting the display indication during normal operation and controlling the drive speed during local speed control operation. The keys below the indicator lamps are used for Start/Stop control and selection of the operating site.

The DISPLAY MODE key is used to change the mode of the display or to return to the Display Mode from either the Quick Menu or the Extend Menu mode.

The QUICK MENU key gives access to the parameters available for the Quick Menu setup. Parameters in this menu are the 12 most important setup parameters for the drive.

The EXTEND MENU key gives access to all parameters.

The CHANGE DATA key is used for changing the value of a parameter selected either in the Extend Menu or the Quick Menu mode. The desired parameter is first selected. Then the CHANGE DATA key is pressed to enable the editing of the parameter. The underline in the display will move under the parameters value to show that it is being edited.

The CANCEL key is used if a change of the selected parameter is not to be carried out.

The OK key is used for confirming a change of the parameter selected.

Page 26

The + and - keys are used to scroll through parameters and to change the value of a chosen parameter. These keys are also used to change the local reference. In Display Mode, these keys are used to switch between readouts.

The v and w keys are used to select a parameter group and also to move the cursor to the desired digit when changing numerical values.

Indicator Lamps

At the bottom of the control panel is a red alarm LED, a yellow warning LED, and a green poweron LED.

AUTO START is used if the drive is to be started via the control terminals and/or serial communication. When a remote start signal is active, the drive will start if the AUTO START key has been pressed.

WARNING

Unintended Start!

In Auto Mode, a start signal via digital inputs may cause drive to start at any time. The drive, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness in Auto Mode could result in death, serious injury, or equipment or property damage.

red yellow green

If certain threshold values are exceeded, the alarm and/or warning lamps will flash and text describing the alarm or warning condition will be displayed.

Local Control

Below the indicator lamps are keys which are used to determine the point of control. Each of these keys can be individually enabled or disabled using parameter 012 through 015. The Hand Start and Auto Start keys will also be disabled if any of the control terminals are programmed for either Remote Hand or Remote Auto.

The HAND START key is used if the drive is to be started from the control panel. Pressing HAND START will give a start command to the drive.

NOTE If a minimum speed is set in parameter 201, Output Frequency, Low Limit, the motor will start and ramp up to this frequency when HAND START is pressed. If drive is running in Auto Mode when the HAND START key is pressed, drive control will switch to Hand Mode.

The OFF/STOP key is used for stopping the connected motor in either the Hand or Auto mode. Enable or disable via parameter 013. If this stop function is activated, the second line in the LCD display will flash.

The RESET key is used for manually resetting the drive after a fault trip (alarm). In this case, the top line of the display will show TRIP (RESET). If the top line of the display shows TRIP (AUTO START), the drive will automatically restart. If the top line of the display shows TRIPLOCK (DISC. MAINS), input power to the drive must be removed before the trip can be reset.

Display Modes

In Auto operational mode, information is displayed in any of three programmable displays. Pressing the DISPLAY MODE key enters display mode and toggles between modes I and II. While in Display mode, the [+] and [-] keys scroll through all data display options. When in Mode II, holding down the DISPLAY MODE key enters Mode III which identifies the units on the top line that the display is showing. Mode IV is available only in local Hand operation and displays the local speed reference.

In normal operation, three data readouts can be shown on the first (top) line of the display. Parameters 008, 009 and 010 select the data displayed on the top line. One readout is available for the large display (line 2). Parameter 007, Large Display Readout, selects the data displayed on line 2. The list on the next page defines the operating data that can be selected for the display readouts.

During an alarm (fault trip), ALARM and the alarm number are shown on the large display. An explanation is given in line 3 or in lines 3 and

4. For a warning, WARN. and the warning number are shown with an explanation in line 3 and/or 4. Both alarms and warnings cause the display to flash.

Line 4 (bottom line), in normal operation, automatically displays the operating status of the drive.

The active setup number and an arrow indicating the direction of motor rotation is shown on the right side of the large display. Clockwise indicates forward and counterclockwise indicates reverse. The arrow body is removed if a stop command is given or if the output frequency falls below 0.01 Hz.

Load and Motor Parameters 100 through 118

This parameter group controls output power and other output characteristics of the drive.

For correct operation, motor nameplate data must be entered into parameters 102 through 106 either through the Quick Menu or the Extended Menu. In addition, automatic motor adaptation, DC braking and motor thermal protection can be set by this parameter group.

101 101 Torque Characteristics ( VT CHARACT) Value:

★ Automatic Energy Optimization

(AEO FUNCTION) [0] Parallelmotors (MULTIPLE MOTORS) [1]

Function:

This parameter configures the drive for single or multiple motor operation.

100 Configuration (CONFIG. MODE) Value:

★ Open loop (OPEN LOOP) [0]

Closed loop (CLOSED LOOP) [1]

Function:

This parameter is used for selecting closed loop or open loop operation.

Description of choice:

If Open loop is selected, speed control is changed directly by the speed reference signal. Any feedback signal applied to the drive will have no effect on the drives speed.

If Closed loop is selected, the internal process regulator is available to accept feedback signal(s) to provide the desired speed regulation.

NOTE It is important to set parameter 100, Configuration, properly when closed loop operation is required. When open loop is selected, parameters associated with setting up PID controller are not accessible.

The AEO function will automatically and continuously monitor the load and adjust the output voltage to maximize motor and drive efficiency and performance. After the motor reaches the set speed, the AEO function reduces the output voltage to the motor, if the load will allow. When the load is light, the voltage is reduced, as shown in the graph below. This lower voltage reduces motor heating and motor noise, and increases efficiency.

Description of choice:

Select Automatic Energy Optimization (AEO) for all single motor applications. When AEO has been selected, only one motor may be connected to the drive at a time.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

107 Automatic Motor Adaptation, AMA

(AUTO MOTOR ADAPT)

Value:

★ Optimization disable (NO AMA) [0]

Automatic adaptation (RUN AMA) [1] Limited AMA (RUN LIMITED AMA) [2]

Function:

Automatic Motor Adaptation (AMA) is an advanced procedure that measures electrical characteristics of the motor. This procedure does not cause the motor to run.

AMA optimizes the adjustment of the drive to the motor. This feature is particularly useful when the drive-to-motor cable length is long, and with nonstandard motors or high hp motors. Although it is not necessary to run AMA, it is highly recommended for optimum operation and increases the capability of the Automatic Energy Optimization function selectable in parameter 101, Torque Characteristics.

For the best adjustment of the drive, it is recommended to carry out AMA on a cold motor.

The following must be noted when either AMA function is used:

- Before running AMA, the correct nameplate data for the motor must be entered in parameters 102 through 106.

- Total automatic motor adaptation may take up to 10 minutes.

- Alarms and warnings will be shown in the display if faults occur during motor adaptation.

- AMA can only be carried out if the rated motor current of the motor is at least 35% of the rated output current of the drive.

Description of choice:

Select Automatic Adaptation if the drive is to carry out a complete automatic motor adaptation procedure.

Select Limited AMA if an LC-filter has been placed between the drive and the motor, for a motor with 6 or more poles, or if Automatic

Adaptation was unsuccessful. Some drives may display Automatic Adaptation with LC-filter rather than Limited AMA. The functions are

the same.

Procedure for Automatic Motor Adaptation:

1. Set motor parameters 102 through 106 according to motor nameplate data.

2. Connect 24 VDC from terminal 12, or from external source, to terminal 27.

3. Select either Automatic Adaptation or Limited AMA in parameter 107, Automatic Motor Adaptation.

4. Start drive by pressing Hand Start or connect terminal 18 (start) to terminal 12 and press Auto Start.

DC Braking

Applying DC current to the motor will brake the motor. Parameter 114, DC Braking Current, sets the DC braking current as a percentage of the rated motor current. Parameter 115, DC Braking Time, sets the amount of time that the DC current will be applied. Parameter 116, DC Brake Cut-in Frequency, sets the frequency at which DC braking begins when the motor decelerates during a stop.

If terminal 19 or 27 (parameters 303 or 304 Digital Input) has been programmed to DC Braking Inverse and shifts from logic 1 to logic 0, the DC braking will be activated immediately.

When the start signal on terminal 18 changes from logic 1 to logic 0, the DC braking will be activated when the output frequency becomes lower than the brake cut-in frequency.

If a DC brake current is set in parameter 114, the drives switching frequency will be limited to 4 kHz during the braking.

CAUTION

Motor Damage!

A high braking current supplied for a long time will overheat the motor. Use only the DC braking current and time required. Excessive braking current may damage the motor.

Also, do not use DC braking function if inertia of driven load is more than 20 times inertia of motor. Excessive load inertia may damage the motor.

NOTE Most HVAC applications do not required braking or holding. It is suggested that parameter 114 remain set at 0 unless braking or holding torque is required.

Function:

The drive is able to monitor the motor temperature in two different ways:

By a thermistor installed in the motor. The thermistor is connected to one of the analog input terminals (53 or 54).

Calculation of the thermal load by the Electronic Thermal Relay (ETR) is based on current, frequency and time. This is compared with the rated motor current and the rated motor frequency. The calculations take into account the reduced cooling of the motor at low speeds.

ETR Tip 1 through 4 and ETR Warning 1 through 4 correspond to the four drive setups. This enables the use of the ETR function to protect up to four different motors if a different setup is used for each different motor.

NOTE If multiple setups are used, be sure to program complete motor data (parameters 102 through

106) and parameter 117 in each setup.

Description of choice:

Select No protection if no warning or trip is desired when the motor is overheated.

Motor Thermal Protection

Reference Handling

Reference handling is shown in the block diagram at the bottom of this page. The block diagram shows how a change in a parameter can effect the resulting reference.

It is possible to have both internal preset references and external references at the same time. In parameter 210, Reference Type, a choice is made of how the preset references are to be combined with the external references.

Parameters 203 to 205, Reference Handling, Minimum and Maximum Reference, and parameter 210, Reference Type, define the way reference handling is carried out. These parameters are active both in closed loop and open loop operation.

In closed loop operation, the resulting reference is affected by parameters 418 and 419, Setpoint 1 and 2, as well as by remote references.

Remote references can be:

1) external references, including analog inputs 53, 54 and 60; pulse references through terminals 17 or 29 and references from serial communication

2) preset references

The resulting reference can be shown in the display as a percentage or as a selected unit of measure. The sum of the external references can be displayed in a percentage of the range between Minimum Reference to Maximum Reference. Select External Reference, [%] or the desired unit in parameters 007 through 010, Display Readout, to display the reference value.

An independent local reference exists, where the resulting reference is set by means of the [+] and [-] keys. In all cases, the output frequency range is limited by parameter 201, Output Frequency Low Limit, and parameter 202, Output Frequency High Limit.

NOTE If local reference is active, drive is always in Open Loop, regardless of choice made in parameter 100, Configuration.

The unit of the local reference can be set either as Hz or as a percentage of the output frequency range. The unit is selected in parameter 011, Unit of Local Reference.

203 Reference Handling (REFERENCE SITE) Value:

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Page 46

Function:

This parameter chooses the active resulting reference. If Hand/Auto linked reference is selected, the resulting reference will depend on

whether the drive is in Hand or Auto mode.

The table below shows which reference is active when Hand/Auto linked reference, Remote reference or Local reference has been selected. The Hand mode or Auto mode can be selected via the keypad or by a digital input set in parameters 300 through 307 Digital

Inputs.

The unit for the reference can be seen from the following table:

Unit

Parameter 100 Configuration = Open loop Hz Parameter 100 Configuration = Closed loop Par. 415

Description of choice:

Minimum Reference is the lowest reference value that can be set for the drive.

205 Maximum Reference (MAX. REFERENCE) Value:

If parameter 100, Configuration = Open loop, parameter 204, Minimum Reference, to 1000.000 Hz ✭60.000 Hz

Description of choice:

If Hand/Auto linked reference is chosen, the motor speed in Hand mode will be set by the local reference, while in Auto mode it is set by the remote references and any setpoints selected.

If Remote reference is selected, the motor speed will depend on remote references and any setpoints selected, regardless of whether Hand mode or Auto mode has been chosen.

If Local reference is selected, the motor speed will only depend on the local reference set via the control panel, regardless of whether Hand mode or Auto mode has been selected.

204 Minimum Reference (MIN. REFERENCE) Value:

If parameter 100, Configuration = Open loop,

0.000Hz to parameter 205, Maximum Reference. ✭ 0.000 Hz

If parameter 100 Configuration = Closed loop, parameter 413, Minimum Feedback, t o parameter 205, Maximum Reference. ✭ 0.000 Hz

Function:

The Minimum Reference sets the minimum value of the sum of all references. If Closed loop has been selected in parameter 100,

Configuration, the minimum reference is limited by parameter 413, Minimum Feedback.

If parameter 100, Configuration = Closed loop, parameter 204, Minimum Reference, to parameter 414, Maximum Feedback. ✭60.000 Hz

Function:

The Maximum Reference sets the maximum value of the sum of all references. If Closed loop has been selected in parameter 100, Configuration, the maximum reference cannot be set above parameter 414, Maximum Feedback. The Maximum Reference is ignored when the local reference is active.

The reference unit can be determined from the following table:

Unit Parameter 100 Configuration = Open loop Hz Parameter 100 Configuration = Closed loop Par. 415

Description of choice:

Maximum reference is the highest reference value that can be set for the drive.

Minimum reference is ignored when the local reference is active. In this case, minimum reference is determined by parameter 201, Minimum Frequency.

NOTE For fan applications, factory setting of parameter 204 is 6 Hz. For pump applications, factory setting for parameter 204 is 18 Hz.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Page 47

206 Ramp Up Time (RAMP UP TIME) Value:

1 to 3600 seconds ★ Depends on the unit

Function:

The ramp up time is the acceleration time from 0 Hz to the rated motor frequency set in parameter 104. It is assumed that the output current does not reach the current limit set in parameter 215. This determines the maximum acceleration rate for all modes of operation.

Description of choice:

Program the desired accel time. Too long of a ramp up time can cause sluggish drive operation. Too short of a ramp up time can cause the drive to go into current limit during acceleration or cause unacceptable torque pulses in the controlled system.

NOTE For fan applications, factory setting of parameter 206 is 60 seconds. For pump applications, factory setting for parameter 206 is 10 seconds.

Description of choice:

Program the desired decel time. Too long of a ramp down time can cause sluggish operation. Too short of a ramp down time can cause the drive to trip off due to high DC bus voltage or cause unacceptable torque pulses in the controlled system.

NOTE Factory setting of parameter 207 for fan applications, is 60 seconds. For pump applications, factory setting for parameter 207 is 10 seconds.

208 Automatic Ramp Down (AUTO RAMPING) Value:

Disable (DISABLE) [0]

★ Enable (ENABLE) [1]

Function:

This function ensures that the drive does not trip during deceleration if the decel time set is too short. If, during deceleration, the DC bus voltage increases to the maximum value permitted, the drive automatically extends the ramp-down time.

NOTE If auto ramp down is enabled, ramp time could be considerably longer than that set in parameter 207, Ramp Down Time.

207 Ramp Down Time (RAMP DOWN TIME) Value:

1 to 3600 seconds ★ Depends on the unit

Function:

The ramp-down time is the deceleration time from the rated motor frequency set in parameter 104, Motor Frequency, to 0 Hz. This ramp-down time may be automatically extended to prevent an overvoltage trip if the load regenerates to the drive. This determines the maximum deceleration rate for all modes of operation.

Description of choice:

Program this function as Enable to avoid trips caused by too rapid a deceleration.

209 Jog Frequency (JOG FREQUENCY) Value:

Parameter 201, Output Frequency Low Limit, to parameter 202 Output Frequency High Limit ★ 10.0 HZ

Reference Type

The example below shows how the resulting reference is calculated when Preset references are used together with Sum and Relative references set in parameter 210, Reference Type. A formula for calculating the resulting reference is given under Calculation of Resulting Reference. See the drawing under Reference Handling.

Example:

The following parameters have been set:

Parameter 204 Minimum Reference: 10 Hz Parameter 205 Maximum Reference: 60 Hz Parameter 211 Preset Reference: 15% Parameter 308 Terminal 53, Analog Input: Reference Parameter 309 Terminal 53, Min. Scaling: 0 V Parameter 310 Terminal 53, Max. Scaling: 10 V

When parameter 210 Reference Type is set to Sum, one of the adjusted Preset References, parameters 211 through 214, will be added to the external references as a percentage of the reference range. If terminal 53 has an analog input voltage of 4 V, the resulting reference will be:

Parameter 210 Reference type = Sum

Parameter 204 Minimum Reference = 10.0 Hz Reference contribution at 4 V = 16.0 Hz Parameter 211 Preset Reference Resulting reference = 32.0 Hz

If parameter 210 Reference Type is set to Relative, one of the adjusted Preset References parameters 211 through 214 will be totaled as a percentage of the sum of the present external references. If terminal 53 has an analog input voltage of 4 V, the resulting reference will be:

Parameter 210 Reference type = Relative

Parameter 204 Minimum Reference = 10.0 Hz Reference contribution at 4 V = 16.0 Hz Parameter 211 Preset Reference = 2.4 Hz Resulting reference = 28.4 Hz

The graph in the next column shows the resulting reference while the external reference changes from 0 to 10 V. Parameter 210, Reference

Type has been programmed for Sum and Relative. Parameter 211, Preset Reference 1, is programmed for 0%.

210 Reference Type (REF. FUNCTION) Value:

Sum (SUM) [0] Relative (RELATIVE) [1]

★ External/preset (EXTERNAL/PRESET) [2]

Function:

It is possible to define how the preset references are added to the other references. For this purpose, Sum or Relative is used. It is also possible, by using the External/Preset function, to select between the external references and a preset reference.

Description of choice:

If Sum is selected, one of the preset references (parameters 211 through 214, Preset Reference) is added to the other external references as a percentage of the reference range (minimum reference through maximum reference).

If Relative is selected, one of the adjusted preset references (parameters 211 through 214, Preset Reference) is added as a percentage of the total external reference.

If External/Preset is selected, it is possible to shift between the external references and the preset references using terminals 16, 17, 29, 32 or 33 (parameters 300, 301, 305, 306 or 307, Digital Inputs). Preset references are a percentage value of the reference range. External reference is the sum of the analog references, pulse references and any references from serial communication.

NOTE If Sum or Relative is selected, one of preset references is always active. If preset references are not used, set value to 0%.

215 Current Limit (CURRENT LIMIT) Value:

0.1 to 1.1 x rated current ★ rated current

Function:

This is where the maximum output current is set. If the motor attempts to draw more than this amount of current, the drive will reduce its output frequency until the current is less than or equal to the current limit value.

The factory setting corresponds to the rated output current. If the current limit is to be used as motor protection, the rated motor current must be set. If the current limit is set within the range of 1.0 to 1.1 times the rated output current of the drive, the drive can only handle current greater than its rated output intermittently. After the load has been higher than rated output current limit, it must be reduced to a level that is lower than the rated current of the drive for a period of time.

These output frequencies can be programmed in parameters 217 through 220.

In this parameter, Frequency Bypass, Bandwidth, the width of the frequency to be bypassed is defined.

Description of choice:

The bypass bandwidth is equal to the programmed bandwidth frequency. This bandwidth will be centered around each bypass frequency.

0 to 120 or 1000 HZ ★ 120.0 Hz The frequency range depends on the selection made in parameter 200, Output Frequency Range.

Function:

Some systems require that some output frequencies be avoided because of mechanical resonance problems in the system.

Description of choice:

Enter the frequencies to be avoided.

See also parameter 216, Frequency Bypass, Bandwidth.

Note that if the current limit is set to less than the maximum value of the drive, acceleration torque is reduced correspondingly.

Inputs and Outputs Parameters 300 through 328

In this parameter group, the functions of the drive input and output terminals are defined. The digital inputs are through terminals 16, 17, 18, 19, 27, 32 and 33. Inputs are programmed by parameters 300 through 307. The table below shows the functions available for input.

Digital inputs require a signal of 0 or 24VDC. A signal lower than 5VDC is a logic 0, while a signal higher than 10 VDC is a logic 1.

The terminals for the digital inputs can be connected to the internal 24 VDC supply through terminals 12 and 13, or an external 24VDC supply can be connected.

The drawings at the right show one setup using the internal 24VDC supply and one setup using an external 24VDC supply.

Switch 4 is used for separating the common potential of the internal 24VDC supply from the common potential of an external 24VDC supply. Switch 4 is the DIP switch on the far right of the group of DIP switches located on the lower right of the control card, just above the control terminals.

When Switch 4 is in the OFF position, the external 24VDC supply is galvanically isolated from the drive.

Page 53

Function:

In parameters 300 through 307, Digital Inputs, the functions of terminals 16 through 33 are selected.

These options are shown in the table on the previous page.

Description of choice:

No Function is selected if the drive is not to react to signals transmitted to the terminal.

Reset allows reset of the drive after a resettable fault. Not all faults can be reset without removing and reapplying the input power. Faults that require the removal of input power are called trip lock faults. See Warnings and Alarms.

Coasting Stop, Inverse is used to release the motor immediately by turning off the output transistors. The motor will coast freely to a stop. Inverse indicates a closed terminal sends the stop signal. Logic 0 implements coasting to a stop.

Reset and Coasting Stop, Inverse is used for activating coasting stop at the same time as reset. Inverse indicates a closed terminal sends the stop signal. Logic 0 implements coasting stop and reset.

DC Braking, Inverse is used for stopping the motor by energizing it with a DC voltage for a given time, as set by parameters 114 and 115. Inverse indicates a closed terminal sends the braking signal. Logic 0 implements DC braking. See the DC braking parameters.

Safety Interlock is the s ame as Coasting Stop, Inverse, except Safety Interlock generates an alarm message on the display when terminal 27

is logic 0. The alarm message will also be active through digital outputs 42 and 45 and relay outputs 1 and 2, if programmed for Safety Interlock.

Start is selected for a remote Start/Stop command. Logic 1 = Start. Logic 0 = Stop.

Reversing is used for changing the direction of rotation of the motor. Logic 0 is for forward. Logic 1 is for reverse. The drive can be safely reversed while it is driving the motor. The reversing signal only changes the direction of rotation, it does not activate the start function. It is not active in Closed Loop mode.

Freeze Reference freezes the present reference. The frozen reference can only be changed by means of Speed Up or Speed Down. The frozen reference is saved after a stop command and when power is removed.

Freeze Output freezes the present output frequency. The frozen output frequency can now only be changed by means of Speed Up or Speed Down.

NOTE If Freeze Output is active, the drive cannot be stopped via terminal 18.

To stop the drive when Freeze Output is active, one of the four methods listed below must be used.

Turn off the Freeze Output function and perform a normal stop. Press the keypad Off/Stop key. Remove the control voltage to terminal 27. If terminal 19 is programmed in parameter 303 for DC Brake Inverse, remove the control voltage to it.

Selection of Setup, Lsb* and Selection of Setup, Msb** enables digital selection of the four possible setups. To enable this, parameter 002 Active Setup must be set to Multi Setup.

Setup, Msb Setup, Lsb Setup 1 0 0 Setup 2 0 1 Setup 3 1 0 Setup 4 1 1

*Lsb - Least significant bit. **Msb - Most significant bit.

Preset Reference, on is used for switching between remote controlled reference and preset reference. This assumes that Remote/preset has been selected in parameter 210, Reference Type. Logic 0 = remote controlled references active; logic 1 = one of the four preset references is active in accordance with the table below.

Preset Reference, Lsb and

Preset reference, Msb enables a

choice of one of the four preset references, in accordance with the table below.

Reversing and Start is used for Start/Stop and reversing using the same signal. A start signal through terminal 18 starts the drive in the forward direction. If both terminal 18 and a reversing and start terminal are given a logic 1 at the same time, the drive will not start. It is not active in Closed Loop.

Preset ref. msb Preset ref. lsb Preset ref. 1 0 0 Preset ref. 2 0 1 Preset ref. 3 1 0 Preset ref. 4 1 1

Speed Up and Speed Down are selected if digital control of the up/ down speed is desired. This function is only active if Freeze Reference or Freeze Output has been selected.

Page 54

As long as there is a logic 1 on the terminal selected for Speed Up, the reference or the output frequency will increase by the Ramp-up Time set in parameter 206.

As long as there is a logic 1 on the terminal selected for Speed Down, the reference or the output frequency will decrease by the Ramp-down Time set in parameter 207.

Pulses (logic 1 minimum high for 3ms and a minimum pause of 3ms) will lead to a change of speed of 0.1% (reference) or 0.1 Hz (output frequency).

Example:

Terminal Terminal Freeze ref./

(16) (17) Freeze output No speed change 0 0 1 Speed down 0 1 1 Speed up 1 0 1 Speed down 1 1 1

The speed reference frozen through the control panel can be changed even if the drive has stopped. In addition, the frozen reference will be retained in memory after power interruption.

Run Permissive. Run Permissive is used to require a second run permission signal in addition to the normal run command, either in Hand or Auto mode. When a run command alone is given, the display will show RUN REQ., but the drive will not start. The drive can also indicate that a run has been requested through one of the transistorized or relay outputs. When, in addition to the run command, a logic 1 is applied to the Run Permissive terminal, the drive will run. If more than one terminal is programmed for Run Permissive, a logic 1 at any of these terminals will allow the drive to run.

Jog is used to start the drive and run it at the frequency set in parameter 209, Jog Frequency. Jog is active in both Hand and Auto mode.

Jog is not active if a stop command has been given through the keypad or terminal 27.

Pulse reference is selected if the frequency of a pulse train is to be used as a reference signal. 0 Hz corresponds to parameter 204,

Minimum Reference. The frequency set in parameter 327, Pulse Reference, Maximum Frequency corresponds to parameter 205 Maximum Reference.

Pulse feedback is selected if the frequency of a pulse train is to be used as a feedback signal. Parameter 328, Pulse Feedback, Maximum Frequency is the pulse frequency that corresponds to maximum feedback.

Hand start is selected if an external signal is used to switch the drive to Hand mode. A logic 1 (Hand Start active) will start the motor. A logic 0 will stop the motor. The drive will then be in OFF/STOP mode, unless there is an active Auto Start signal from an external source. Programming one of the digital inputs for Hand Start will disable the LCP Hand Start and Auto Start keys.

WARNING

Unintended Start!

With Hand Start active, digital inputs may cause drive to start at any time. The drive, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness with Hand Start active could result in death, serious injury, or equipment or property damage.

Auto start is selected if an external signal is sent to switch the drive to Auto mode. When a start signal is active on the control terminals or the serial communication port, the drive will start the motor. If Auto Start and

Hand Start are active at the same time on the control terminals, Auto Start will have the higher priority. If Auto Start and Hand Start are not

active, the motor will stop and the drive will then be in the OFF/STOP mode. Programming one of the digital inputs for Auto Start will disable the LCP Hand Start and Auto Start keys.

Data change lock is selected if changes to parameters are not to be made via the control panel. It is be possible to change parameters through the serial bus.

Page 55

Analog Inputs

Two analog inputs for voltage signals, terminals 53 and 54, and an analog input for current, terminal 60, are provided for reference and feedback signals. A thermistor can be connected to the voltage inputs, terminals 53 or 54.

Feedback. If a feedback signal is connected, a voltage input may be connected to either terminal 53 or 54, or a current input conected to terminal 60. If a two zone PID control is used, the feedback signals must be voltage inputs and applied to terminals 53 and 54. See Feedback Handling.

The two analog voltage inputs can be scaled over the range of 0to10VDC. The current input can be scaled over the range of 0 to20mA.

The table below shows the possible analog input programming.

Parameter 317, Time Out, and Parameter 318, Function After Time Out, allow activation of a time-out function on all analog inputs. If the signal value of the reference or feedback signal connected to one of the analog input terminals drops below 50% of the minimum scaling, the function set in parameter 318, Function After Time Out, will be activated after the time-out set in parameter 317.

If parallel sensors are used, the thermistors/thermal switches can be connected in series. The drive will shut down when the total resistance exceeds 3 kohms.

NOTE When a thermistor is mounted in motor wiring, a breakdown of insulation between thermistor and motor can feed high voltage back to drive control terminals. To comply with protective extra-low voltage (PELV) grounding requirements, if applicable, thermistor must be mounted externally.

Parameter 117, Motor Thermal Protection, must be programmed for Thermal Warning or Thermistor Trip, and the thermistor must be

inserted between terminal 53 or 54, analog voltage input, and terminal 50, 10V supply.

Application Functions Parameters 400 through 427

Special functions of the drive are set up in this parameter group. This includes the proportional, integral, derivative controller (PID) and setting the sleep mode function.

Additionally, this parameter group includes:

Reset function Flying start Interference reduction Lossof load Carrier frequency Selectionofprocess units

WARNING

Unintended Start!

With any automatic reset active, digital inputs may cause drive to start at any time. The drive, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness with automatic reset active could result in death, serious injury, or equipment or property damage.

400 Reset Function (RESET FUNCTION) Value:

Manual reset (MANUAL RESET) [0] Automatic reset x 1 (AUTOMATIC X 1) [1] Automatic reset x 2 (AUTOMATIC X 2) [2] Automatic reset x 3 (AUTOMATIC X 3) [3] Automatic reset x 4 (AUTOMATIC X 4) [4] Automatic reset x 5 (AUTOMATIC X 5) [5] Automatic reset x 10 (AUTOMATIC X 10) [6] Automatic reset x 15 (AUTOMATIC X 15) [7] Automatic reset x 20 (AUTOMATIC X 20) [8]

★ Infinite automatic reset (INFINITE AUTOMATIC) [9]

401 Automatic Restart Time

(AUTORESTART TIME)

Value:

0 to 600 seconds ★ 10 sec.

Function:

This parameter sets the automatic reset time delay until each reset is attempted. One of the automatic resets must be selected in parameter 400, Reset Function.

Description of choice:

Set the desired time before each restart attempt.

CAUTION

Motor Rotation!

When parameter 402, Flying Start, is enabled, motor may turn forward and reverse a few revolutions even with motor stopped. In highly dynamic pumping processes, it is recommended to disable Flying Start function. Using Flying Start in highly dynamic pumping processes could result in injury or equiment or property damage.

402 Flying Start (FLYING START) Value:

★ Disable (DISABLE) [0]

Enable (ENABLE) [1] DC brake and start (DC BRAKE AND START) [3]

Function:

This function makes it possible for the drive to catch a rotating motor when the drive is started. The drive will sense the speed of rotation and direction of rotation of the motor and synchronize with it.

This function is active whenever a start command is present.

For the drive to catch the spinning motor, the motor speed must be lower than the maximum frequency set in parameter 202.

Function:

This parameter allows a choice of manual or automatic reset after a fault trip. There is also a choice of the number of times the unit will attempt to restart. The time between each attempt is set in parameter 401, Automatic Restart Time.

Description of choice:

If Manual Reset is selected, the Reset key must be pressed or a digital input given to reset the drive.

If auto reset after a fault trip is desired, select one of the Automatic reset choices.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Description of choice:

Select Disable if this function is not required.

Select Enable if the drive is to catch and control a rotating motor.

Select DC brake and start if the drive is to brake the motor by means of the DC brake first, and then start. Ensure that parameters 114 through 116, DC Braking, are set appropriately. Select DC brake and start if the motor may be externally driven at a significant speed in the reverse direction.

NOTE For fan applications, factory setting for Flying Start is Enable. For pump applications, factory setting for Flying Start is Disable.

Page 64

Sleep Mode

Sleep mode makes it possible to stop the drive when the system demand drops below a preset level. When the demand increases to a higher preset level, the drive will restart. A significant amount of energy can be saved using sleep mode. Unlike a set-back time clock, the drive is always available to run when the demand reaches the preset wake up level. Sleep mode is not active if Local Reference is selected in parameter 203, Reference Handling, or if the Jog function activates via digital inputs. Sleep mode operates in both Open Loop and Closed Loop.

Activate sleep mode in parameter 403, Sleep Mode Timer. In this parameter, set how long the output frequency must be lower than the sleep frequency set in parameter 404, Sleep Frequency, before sleep mode activates. After the set time, the drive will ramp down the motor to a stop, as controlled by parameter 207, Ramp Down Time. If the output frequency needed to meet the system demand rises above the sleep frequency during the timed period, the drive will simply ramp up to the demanded frequency.

When the sleep mode timer expires and the drive is stopped in sleep mode, a theoretical output frequency is calculated based upon the reference signal. When the theoretical output frequency rises above the frequency set in parameter 405, Wake-up Frequency, the drive will restart the motor and ramp up to the commanded reference.

For closed loop operation, it may be useful to over satisfy the system before putting the drive into sleep mode. The boost setpoint parameter provides for this. After the sleep mode timer expires, the drive will reset the set point based on the value in parameter 406, Boost Setpoint. Once this new setpoint is satisfied, the drive enters sleep mode. A setting of 100% in parameter 406, Boost Setpoint, indicates no setpoint boost. Boost setpoint is only active in Closed Loop, selected in parameter 100, Configuration.

Sleep Mode Frequency Response

Page 65

WARNING

Unintended Start!

In Sleep Mode, a start signal via digital inputs may cause drive to start at any time. The drive, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness in Sleep Mode could result in death, serious injury, or equipment or property damage.

405 Wake-up Frequency (WAKEUP FREQUENCY) Value:

Parameter 404 to parameter 202, Maximum Frequency

★ 60 Hz

Function:

When the theoretical output frequency exceeds the preset value, the drive restarts the motor.

Description of choice:

Set the required frequency.

403 Sleep Mode Timer (SLEEP MODE TIMER) Value:

0 to 300 seconds (OFF) ★ OFF

Function:

This parameter enables the drive to stop the motor if the load on the system is minimal. The timer starts when the output frequency drops below the frequency set in parameter 404, Sleep Frequency. When the time set has passed, the drive will stop. The drive will restart when the theoretical output frequency exceeds the frequency set in parameter 405, Wake-up Frequency.

Description of choice:

Select OFF if this function is not wanted.

Set the amount of time that the drive must run at or below the sleep frequency before it stops and goes to sleep.

404 Sleep Frequency (SLEEP FREQUENCY) Value:

0.0 to parameter 405, Wake-up Frequency ★ 0.0 Hz

Function:

When the output frequency falls below this set value, the timer set in parameter 403, Sleep Mode Timer, will start. The drives speed will follow the reference signal until the timer times out.

406 Boost Setpoint (BOOST SETPOINT) Value:

0 to 200 % ★ 100 % of setpoint

Function:

This function can only be used if Closed Loop has been selected in parameter 100, Configuration.

In some systems, it may advantageous to increase the set point of the system before the drive stops the motor. This extends the time that the drive will be stopped and reduces cycling of the motor.

Description of choice:

Set the required Boost Setpoint as a percentage of the resulting reference under normal operation. 100% corresponds to the boost.

Description of choice:

Choose the output frequency at which the drive will activate the sleep mode timer. It is generally best to set SLEEP FREQUENCY equal to the minimum frequency set in parameter 201, Output Frequency Low Limit and parameter 204, Minimum Reference. This is because the sleep mode isnt active until after the drive output frequency equals the sleep frequency. If the sleep frequency is less than the minimums, the sleep mode cannot activate.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Page 66

407 Switching Frequency (SWITCHING FREQ.) Value:

Depends on the current rating of the unit.

Function:

The value of this parameter determines the maximum switching frequency of the inverter. If Fixed Switching Frequency has been selected in parameter 408, Interference Reduction Method, this will be the fixed inverter switching frequency. Changing the switching frequency may reduce audible noise from the motor. The output frequency of the drive can never be a greater than 1/10 of the switching frequency.

Description of choice:

When the motor is running, the switching frequency may be adjusted by parameter 407, Switching Frequency, until the sound level is as low as possible.

408 Interference Reduction Method

(NOISE REDUCTION)

Value:

★ ASFM (ASFM) [0]

Fixed switching freq. (FIXED SWITCHING FREQ.) [1] LC filter fitted (LC-FILTER CONNECTED) [2]

Function:

Used to select different methods for reducing the amount of audible noise from the motor.

Description of choice:

ASFM (Automatic Switching Frequency Modulation) uses the maximum switching frequency possible while providing the output required by the load. The load is automatically monitored and the switching frequency set accordingly. The maximum switching frequency is set in parameter 407, Switching Frequency.

Switching frequencies higher than 4.5 kHz will result in automatic derating of the maximum continuous output current of the drive. The derate is linear from 4.5 kHz to the maximum switching frequency of the drive. At maximum switching frequency, the continuous output current from the drive will be limited to 60% of the rated current. To avoid possible problems at high load when using a high switching frequency, it may be desirable to select Automatic Switching Frequency Modulation in parameter 408, below.

NOTE Switching frequencies higher than 4.5 kHz automatically derate maximum continuous output of drive.

FixedSwitching Frequency makes it possible to set a fixed switching frequency. The switching frequency is set in parameter 407, Switching

Frequency.

LC-filter fitted is to be used if an LC filter is installed between the drive

and the motor. This prevents excessive heating of the LC filter.

409 Function in Case of No Load

(FUNCT. LOW CURR.)

Value:

Trip (TRIP) [0]

★ Warning (WARNING) [1]

Function:

This parameter can be used for monitoring the V-belt of a fan or other power transmission component to make sure it has not broken. This function is activated when the output current goes below the current level set in parameter 221, Warning: Low Current. This function is not active during a start until the drive has reached the speed reference. It is also not active while the drive is stopped or while it is decelerating to a stop.

Description of choice:

In the case of a Trip, the drive will stop the motor if the output current drops below the value set in parameter 221.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

If Warning is selected, the drive will give a warning if the output current drops below the value set in parameter 221.

(MAINS IMBALANCE)

Value:

Trip (TRIP) ★ [0] Autoderate & Warning (AUTODERATE & WARNING) [1] Warning (WARNING) [2]

Function:

This determines the action of the drive when one of the incoming power phases is lost. Some action is required to control the level of ripple voltage on the DC bus to avoid damage to the DC bus capacitors. Drive display will show MAINS PHASE LOSS.

411 Function at Drive Overtemperature

(FUNCT. OVERTEMP)

Value:

Trip (TRIP) ★ [0] Autoderate & Warning (AUTODERATE & WARNING) [1]

Function:

Select the function to be activated when the drive is exposed to an overtemperature condition.

Description of choice:

At Trip, the drive stops the motor and exports an alarm.

Description of choice:

At Trip, the drive stops the motor within a few seconds (depending on drive size).

If Autoderate & Warning is selected, the drive will export a warning and reduce the output current to 30% of maximum current to maintain operation.

CAUTION

Input Phase Loss!

If Warning is selected, life expectancy of the drive could be reduced if input phase loss persists. Select Warning only when input phase loss is known to be temporary.

At Warning, only a warning will be exported when an input phase loss occurs, but in severe cases, other extreme conditions might result in a trip.

For drives with software version 2.0 or later, select Autoderate & Warning. Set parameter 412, Trip Delay Overcurrent, to OFF.

CAUTION

At Autoderate & Warning, the drive first reduces the switching frequency to minimize internal loss. If the overtemperature condition persists, the drive reduces the output current until the heat sink temperature stabilizes. A warning is issued when the function is active.

For drives with software version 2.0 or later, select Autoderate & Warning. Set parameter 412, Trip Delay Overcurrent, to OFF.

412 Trip Delay Overcurrent

(OVERLOAD DELAY)

Value:

OFF or 0 to 60 sec. ★ OFF

Function:

When the output current has reached the current limit set in parameter 215, Current Limit, and remains there for the time selected in this parameter, the drive will trip.

Description of choice:

Select how long the drive will run in current limit before it trips.

Overheating Hazard!

At phase loss, the cooling fan of NEMA 12 drives cannot be powered. To avoid overheating, an external power supply can be connected. Contact Trane for further information. Failure to provide fan cooling may result in equipment damage.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Page 69

PID for Process Regulation

The built-in proportional, integral, derivative (PID) controller in the drive maintains a constant condition (pressure, temperature, flow, etc.) in the system. It adjusts motor speed based upon a reference and/or setpoint and the feedback signal. The PID controller is activated by setting parameter 100, Configuration, to Closed loop.

Reference (Setpoint)

In parameter 205, Maximum Reference, the maximum value of the sum of all reference signals is set.

The Minimum Reference, set in parameter 204, indicates the smallest value that the resulting reference can assume.

A transmitter supplies the PID controller with a feedback signal from the process to indicate its current state. The type of feedback signal in use depends upon the type of process.

This means that deviations that occur between the reference/setpoint and the actual process state are sensed. Such deviations are compensated for by the PID regulator by adjusting the output frequency as required by the difference (or error) between the reference/setpoint and the feedback signal.

The PID controller in the drive has been designed for use in HVAC applications and to perform a number of specialized functions. Previously, it was necessary for a building management system to handle these special functions by installing extra modules to program the system.

With the TR1, there is no need for extra modules to be installed. Only the reference and/or setpoint and a selected feedback signal need to be programmed. An advanced feature of the TR1 is the drives ability to accept two feedback signals, making two-zone regulation possible.

Voltage drop in long control cables can be compensated for by using the scaling parameters for the analog inputs.

Feedback

The feedback signal must be connected to the drive according to the table below, depending on the type of feedback signal and the settings of the associated parameters listed.

The reference range cannot exceed the feedback range.

If multiple Preset References are required, use multiple setups or set them in parameters 211 to 214 Preset Reference. See Reference Handling.

If a current signal is used as a feedback signal, voltage can be used as an analog reference. Use the table below to decide which terminal to use and which parameters to program.

Reference type Terminal Parame ters Pulse 17 or 29 301 or 305 Voltage 53 or 54 308, 309, 310 or

Terminals that are not used should be set to No function.

Inverse Regulation

Normal regulation means that the motor speed increases when the reference/setpoint is higher than the feedback signal. Inverse regulation means that the motor speed decreases when the reference/setpoint is higher than the feedback signal. If there is a need for inverse regulation, inverse must be programmed in parameter 420, PID

Normal/Inverse Control.

Current 60 314, 315, 316 Bus feedback 1* 68 and 69 537 Bus feedback 2* 68 and 69 538 * The bus feedbacks can only be set by serial communication.

If two analog feedback signals are to be used, they both must be voltage signals.

The Minimum Feedback and Maximum Feedback, parameters 413 and 414, must be set for the feedback signals. The type of process unit for the signals is selected in parameter 415, Process Units.

311, 312, 313

Anti-windup

The process controller is factory set with an active anti-windup function. This function ensures that when either a frequency limit or a current limit is reached, the integrator will be reset to zero. If the frequency limit or current limit is cleared, the integrator will turn on again. This function can be disabled in parameter 421, PID Anti-windup.

Start-up Conditions

In some applications, the optimum setting of the process regulator takes a long time to reach. In such cases, a start-up frequency can be entered in parameter 422, PID Start-up Frequency. The drive will ramp directly to this frequency before PID control begins. This avoids control by deviation between the reference/setpoint and the actual state of the process during acceleration. It also avoids overshoot of the process requirement during acceleration due to lag in the feedback signal.

Page 70

Differentiator Gain Limit

The differentiation control reacts to the rate of change of the error between the setpoint and the feedback signal. This is seldom needed for HVAC applications. If the differentiation function becomes too dominant, the differentiation factor can be limited. This is done in parameter 426, PID Differentiator Gain Limit.

Lowpass Filter

Noise on the feedback signal can be reduced by using the built-in lowpass filter. Set a suitable lowpass filter time constant. This time constant determines the cutoff frequency of the filter.

If the lowpass filter has been set to 0.1s, the cut-off frequency will be 10 RAD/sec., corresponding to (10/2 x π) = 1.6 Hz. This means that any noise on the feedback signal whose frequency is greater than 1.6 Hz will be filtered out. Choose a suitable time constant in parameter 427, PID Lowpass Filter Time.

Optimization of the Process Regulator

The basic settings have now been made; all that remains to be done is to optimize the proportional gain, the integration time and, if needed, the differentiation time. These are set by parameters 423, 424 and 425. In most processes, this can be done by following the guidelines below.

PID Overview

The block diagram below shows reference and setpoint in relation to the feedback signal.

As can be seen, the remote reference is added to Setpoint 1 or Setpoint 2. The setpoint that is active depends on the value of parameter 417, Feedback Function.

1. Start the motor.

2. Set parameter 423, PID Proportional Gain, to 0.3 and increase it until the feedback signal becomes unstable. Then reduce the value until the feedback signal has stabilized. Now lower the proportional gain by about half (40% to 60%).

3. Set parameter 424, PID Integration Time, to 20 seconds and reduce the value until the feedback signal becomes unstable. Increase the integration time until the feedback signal stabilizes. Now increase the integration time from 15% to 50%.

4. Parameter 425, PID Differentiation Time, is only used in very fast-acting systems and should be left off for most HVAC applications. When it is used, the typical value is 1/4th the value set in parameter 424, PID Integration Time. The differentiator should only be used when the setting of the proportional gain and the integration time have been fully optimized.

Starting and stopping the drive will produce the necessary error signal in the process to set the PID.

Feedback Handling

Handling of the feedback signal(s) can be seen from the block diagram on the next page. The block diagram shows how and by which parameters the feedback handling is affected.

Feedback signals can be voltage, current, pulse and bus feedback signals. In two zone feedback systems, both feedback signals must be voltage signals (terminals 53 and 54). Please note that Feedback 1 consists of bus feedback 1, (parameter 537) added to the feedback signal value of terminal 53. Feedback 2 consists of bus feedback 2, (parameter 538) added to the feedback signal value of terminal 54.

In addition, the drive has an internal calculator capable of converting a pressure signal into a linear flow feedback signal. This function is activated in parameter 416, Feedback Conversion.

The parameters for feedback handling are active both in closed and open loop modes. In open loop, the feedback signal can be displayed on one of the drives meters and the drive can produce warnings if the feedback signal is beyond the range set in parameters 227, Warning: Low Feedback and 228, Warning: High Feedback.

Page 71

Feedback Handling (continued)

During closed loop operation, there are three ways to use the PID controller and setpoint and feedback signals:

1 setpoint and 1 feedback 1 setpoint and 2 feedbacks 2 setpoints and 2 feedbacks

1 Setpoint and 2 Feedbacks

Depending on the feedback function selected in parameter 417, Feedback Function, the two feedback signals will be compared to the setpoint. A description of the individual feedback functions is given in parameter 417. As above, parameter 418, Setpoint 1, will be added to the remote reference, if a remote reference is used.

1 Setpoint and 1 Feedback

In HVAC applications it is often possible to place a pressure or temperature sensor at the farthest significant load and measure actual pressure or temperature in the system. In these cases, the drive's PID controller can respond to system changes, as programmed. When only one setpoint and one feedback signal are used, the drive responds to the feedback signal to match the programmed setpoint in parameter 418, Setpoint 1. (If a remote reference is used, it will be added to the setpoint.)

2 Setpoints and 2 Feedbacks

Whenever two critical zones do not have the same setpoint value, two feedback with two setpoint control is required. Many pumping systems require the monitoring and control of two loads that differ in size and pressure drop. Or this can be effective when controlling different temperature zones in cooling or heating applications. Parameter 418, Setpoint 1, is the setpoint for zone 1. Feedback for zone 1 is the feedback signal at terminal 53. Parameter 419, Setpoint 2, is the setpoint for zone 2 and terminal 54 for feedback 2. Bus Feedback 1 and 2 (parameters 535 and 536) are added to their respective feedback signals, when serial bus data is added to the zone control.

Parameter 417, Feedback Function, selects whether the drive will attempt to have both feedback signals meet the minimum (2 zone min.) or maximum (2 zone max.) to their respective setpoints.

Page 72

416 Feedback Conversion

(FEEDBACK CONV.)

Value:

★ Linear (LINEAR) [0]

Square root (SQUARE ROOT) [1]

Function:

In this parameter, a function is selected which converts a feedback signal from the process to a feedback value that equals the square root of the connected signal.

Function:

This parameter determines the calculation method for two feedback signals. Terminals 53 and 54 are both read in selections [0] through [6]. In each case, if only one feedback signal is received, a zero value will be calculated for the inactive terminal. To read feedback from only one of the two terminals, use Feedback 1 Only (terminal 53) or

Feedback 2 Only (terminal 54) to exclude the inactive terminal.

Feedback 1 = Sum of parameter 535, Bus Feedback 1, (if present) and

the feedback signal value of terminal 53.

This can be used where regulation of a flow is required and the feedback is from a pressure sensor (flow is proportional to the square root of pressure). This conversion makes it possible to set the reference in such a way that there is a linear connection between the reference and the flow required. See diagram below.

Feedback conversion should not be used if two-zone regulation has been selected in parameter 417, Feedback Function.

Description:

If Linear is selected, the feedback signal and the feedback value will be proportional.

If Square root is selected, the drive first takes the square root of the feedback signal.

TR1 drive

Feedback 2 = Sum of parameter 536, Bus Feedback 2, (if present) and the feedback signal value of terminal 54.

Description of choice:

If Minimum is selected, the drive will compare Feedback 1 wi th Feedback 2 and regulate on the basis of the lower feedback value.

If Maximum is selected, the drive will compare Feedback 1 with Feedback 2 and regulate on the basis of the higher feedback value.

If Sum is selected, the drive will total Feedback 1 wit h Feedback 2.

If Difference is selected, the drive will subtract Feedback 1 from Feedback 2.

If Average is selected, the drive will calculate the average of Feedback 1 and Feedback 2.

If 2-zone Minimum is selected, the drive will calculate the difference between Setpoint 1 and Feedback 1 as well as Setpoint 2 and Feedback 2. The drive will regulate its output speed based on the larger difference. A positive difference, (a setpoint higher than the feedback), is always larger than a negative difference.

If 2-zone Maximum is selected, the drive will calculate the difference between Setpoint 1 and Feedback 1 as well as Setpoint 2 and Feedback 2. After the calculation, the drive will use the smaller difference. A negative difference (a setpoint lower than the feedback) is always smaller than a positive difference.

★ Maximum (MAXIMUM) [1]

Sum (SUM) [2] Difference (DIFFERENCE) [3] Average (AVERAGE) [4] Two-zone minimum (2 ZONE MIN) [5] Two-zone maximum (2 ZONE MAX) [6] Feedback 1 only (FEEDBACK 1 ONLY) [7] Feedback 2 only (FEEDBACK 2 ONLY) [8]

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

If Feedback 1 Only is selected, terminal 53 is read as the feedback signal and terminal 54 ignored. Feedback 1 is compared to Setpoint 1 for drive control.

If Feedback 2 Only is selected, terminal 54 is read as the feedback signal and terminal 53 ignored. Feedback 2 is compared to Setpoint 2 for drive control.

NOTE Value of parameter 418, Setpoint 1, is added to any remote reference when Minimum, Maximum, Sum, Difference or Average is selected.

Page 73

418 Setpoint 1

(SETPOINT 1)

Value:

Feedback Minimum to Feedback Maximum ★ 0.000

Function:

Setpoint 1 is used to provide the setpoint reference for PID control with one feedback signal. It is also used for the setpoint for zone one in two-setpoint PID control. External and preset references may be added to its value.

In open loop, Setpoint 1 should be set to 0 to prevent parameter 417, Feedback Function, from affecting the reference.

See description of parameter 417, Feedback Function.

Description of choice:

Set the desired value within the programmed minimum and maximum. The process unit is selected in parameter 415, Process Units.

419 Setpoint 2

(SETPOINT 2)

Value:

Feedback minimum to Feedback maximum ★ 0.000

421 PID Anti-windup

(PID ANTI WINDUP)

Value:

Off (DISABLE) [0]

★ On (ENABLE) [1]

Function:

It is possible to choose whether the PID controller integrator is to continue to sum the error signal when it is not possible to increase or decrease the output frequency to correct the error.

Used in Closed Loop, parameter 100.

Description of choice:

The factory setting is On, which means that the error integrator is cleared if either the current limit, the voltage limit or the maximum or minimum frequency has been reached. The integrator will not function again until regulation is possible. Select Off if the integrator is to continue integrating even if it is not possible to correct the error.

422 PID Start-up Frequency

(PID START VALUE)

Value:

Minimum frequency to maximum frequency

(set by parameters 201 and 202) ★ 0 Hz

Function:

Setpoint 2 is used to provide the setpoint reference for zone two in two-zone PID. In open loop, Setpoint 2 should be set to 0, to prevent parameter 417, Feedback Function, from affecting the reference.

See description of parameter 417.

Description of choice:

Set the required value. The process unit is selected in parameter 415, Process Units.

420 PID Normal/Inverse Control

(PID NOR/INV. CTRL)

Value:

★ Normal (NORMAL) [0]

Inverse (INVERSE) [1]

Function:

This determines how the drives PID controller responds to an error between the setpoint and feedback.

Used in Closed Loop, (parameter 100).

Description of choice:

Select normal when the drive is to reduce the output frequency as the feedback signal increases.

Function:

Each time the drive is given a start command, the start-up frequency is the speed the drive accelerates to before PID control is activated. The drive will follow the acceleration ramp when a start signal is received as if in open loop. When the programmed start-up frequency is reached, it will change to closed loop operation.

Used in Closed Loop, parameter 100.

Description of choice:

Set the required start frequency. For software versions prior to 2.0, do not set this frequency between 0.1 and 7.7 Hz.

NOTE If drive is running in current limit before desired start frequency is obtained, PID control will not be activated. To avoid this, start frequency must be low enough to ensure drive does not go into current limit. This can be done during operation.

Select inverse when the drive is to increase the output frequency as the feedback signal increases.

✭ I

423 PID Proportional Gain

(PID PROP. GAIN)

Value:

0.00 to 10.00 ★ 0.30

426 PID Differentiator Gain Limit

(PID DIFF. GAIN)

Value:

5.0 to 50.0 ★ 5.0

Function:

The proportional gain determines how fast the system responds to a change in feedback.

Used in Closed Loop, parameter 100.

Description of choice:

Quick regulation is obtained by a high gain, but, if the gain is too high, the process may become unstable. See Optimization of the Process Regulator for information on proper adjustment.

424 PID Integral Time

(PID INTEGR.TIME)

Value:

0.01 to 9999.00 sec. (OFF) ★ OFF

Function:

The integrator adds the error signal over time and uses this to correct the speed of the drive.

The integral time is the time needed by the integrator to have the same effect as the proportional gain.

Used in Closed Loop parameter 100.

Description of choice:

Fast regulation is obtained by setting a short integration time. However, if this time is too short, the process will overcorrect and become unstable. See Optimization of the Process Regulator for information on proper adjustment.

425 PID Differentiation Time

(PID DIFF. TIME)

Value:

0.00 (OFF) to 10.00 sec. ★ OFF

Function:

When the differentiator is used, fast changes in the error can sometimes cause unstable operation. In these cases it may be useful to limit the contribution of the differentiator.

Used in Closed Loop, parameter 100.

Description of choice:

A lower limit will improve stability, but will reduce the effect of the differential.

427 PID Lowpass Filter Time

(PID FILTER TIME)

Value:

0.01 to 10.00 ★ 0.01

Function:

Noise on the feedback signal can be reduced by the lowpass filter.

Used in Closed Loop, parameter 100.

Description of choice:

Select the desired time constant (t).

The cut off frequency equals ½πt. For example, if a time constant of 0.1 s is programmed, the cut off frequency for the lowpass filter will be 1/[2π (.1)] = 1.6 Hz.

The PID controller will then only respond to changes in the feedback signal whose frequency is less than 1.6 Hz.

Function:

The differentiator responds to the rate of change of the error signal.

The quicker the error changes, the greater the response from the differentiator.

Used in Closed Loop, parameter 100.

Description of choice:

Fast regulation can be obtained by means of a long differentiation time. If this time is too long, the process may overshoot. The differentiator is generally set of OFF in HVAC applications. See Optimization of the Process Regulator for information on proper adjustment.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

570 Modbus parity and message framing

(M.BUS PAR./FRAME)

Value:

Even parity (EVEN / 1 STOPBIT) [0] Odd parity (ODD / 1 STOPBIT) [1]

★ No parity (NO PARITY / 1 STOPBIT) [2]

Function

This parameter sets the drive Modbus RTU interface to communicate properly with a master controller. The parity (even, odd, or no parity) must be set to match the setting of the master controller. Even and odd parity is sometimes used to allow error checking of a transmitted word.

Description of choice

Because Modbus RTU uses the more efficient CRC (cyclic redundancy check) method for checking for errors, parity checking is seldom used in Modbus RTU networks. Set the drive parity to match the master controller, if appropriate.

571 Modbus communication timeout

(M.BUS COM.TIME.)

Value:

10 ms to 2000 ms ★ 100 ms

Function

This parameter determines the maximum time that the drive will wait between characters sent by the Modbus RTU master controller. When the time expires, the drive assumes it has received the entire message.

Description of choice

Generally, the value of 100 ms is sufficient for Modbus RTU networks, although some Modbus RTU networks may operate with a timeout value as short as 35 ms. If the value is set too short, the drive may miss part of the message. Since the CRC check will be invalid, the drive will ignore the message. The resulting retransmission of messages will slow network communications. A value set too long will cause the drive to wait longer than necessary to determine that the message is complete. This delays response time and could cause the master controller to timeout or slow the network.

Description of choice:

The output frequency of the variable frequency drive can be frozen at the present value at any given time, frozen at parameter 211, Preset Reference 1, frozen at parameter 202, Max. Output Frequency, or stop output and show a fault.

✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.

Serial Communication for FC Protocol

ADDRESS 1

MASTER

ADDRESS 2

Protocols

All TR1 drives have an RS-485 (EIA-485) port which allows controlling the drive by one of four different serial communication protocols. The protocols, which can be selected in parameter 500, Protocol, are:

● Johnson Controls Metasys N2

● Siemens FLN

● Modbus RTU

● FC protocol

Metasys N2 is a registered trademark of Johnson Controls.

FLN is a registered trademark of Siemens.

ADDRESS 31

REPEATER

ADDRESS 126

Packet Communication

Control and Reply Packets

The packet communication in a master/slave system is controlled by the master. The drives are the slaves. A maximum of 31 TR1 drives can be connected to one master unless a repeater is used. If a repeater is used, a maximum of 126 drives can be connected to one master.

The master continuously sends packets addressed to the slaves and awaits reply packets from them. The response time of the slaves is a maximum of 50 ms.

If FC protocol is to be selected, set parameter 500, Protocol to FC protocol .

For further information on operating the drive through N2, FLN, or Modbus RTU communication, request the related operators manual from Trane.

Only a slave that has received a faultless packet addressed to that slave will respond by sending a reply packet.

Broadcast

When a master sends a packet to all slaves connected to the bus at the same time, it is called a broadcast. In broadcast communication, if the packet has been correctly received, the slaves do not send reply packets to the master.

Conversion

The different attributes for each parameter can be seen in the section on factory settings.

Since a parameter value can only be transferred as a whole number, a conversion factor must be used to transfer decimals.

Example:

Parameter 201: Minimum Frequency, conversion factor 0.1. If parameter 201 is to be set to 10 Hz, a value of 100 must be transferred, since a conversion factor of 0.1 means that the transferred value will be multiplied by 0.1. A value of 100 will, therefore, be understood as 10.0.

Warnings and Alarms

A trip can be reset in any one of the following ways: The table below lists the drive fault messages and indicates whether a warning, alarm, or trip-lock occurs. Wherever an X is placed under both warning and alarm, this means that a warning precedes the alarm. An alarm always precedes, or simultaneously accompanies, a trip-lock.

A trip causes the drive to suspend operation by cutting off power to the motor. A trip-lock requires that input power to the drive be removed, the cause of the fault corrected, and the input power restored in order to reset the drive.

1) Manual reset by pressing the RESET key on the keypad

2) A digital input through a digital input terminal

3) Serial communication command

4) Automatic reset

Automatic or manual reset may be selected in parameter 400, Reset

Function. Auto reset will not restore a trip-lock. The number of reset

attempts may be selected or infinite, which allows continuous attempts. A

timer between attempts can be set in parameter 401.

ALARM 22 AMA FAULT

A fault has been found during automatic motor adaptation (AMA). The text shown in the display indicates a fault message.

AMA can only be carried out if there are no alarms during the AMA process.

CHECK 103, 105

Parameter 103 or 105 has a wrong setting. Correct the setting and repeat AMA.

LOW P 105

The motor is too small for AMA to be carried out. If AMA is to be enabled, the rated motor current, parameter 105, must be higher than 35% of the rated output current of the drive.

ASYMMETRICAL IMPEDANCE

AMA has detected an asymmetrical impedance in the motor connected to the system. The motor could be defective.

ALARM 29 HEAT SINK OVER TEMP.

The heatsink temperature became too high. For NEMA 1 drives, the limit is 90°C. For NEMA 12 drives, the limit is 80°C. The tolerance is ±5°C. The fault cannot be reset until the temperature of the heatsink has fallen below 60°C.

The fault could be due to the following:

- Ambient temperature too high

- Air obstructed

- Cooling fan(s) not operating

- Motor leads too long

- Too high a switching frequency

ALARM 30 MISSING MOT.PHASE U

Motor phase U, as indicated by the letters on the output terminal block, is missing or has a high impedance.

Remove power to the drive and check motor phase U.

MOTOR TOO BIG

The motor connected to the system is too big for AMA to be carried out. The setting in parameter 102 does not match the motor used.

MOTOR TOO SMALL

The motor connected to the system is too small for AMA to be carried out. The setting in parameter 102 does not match the motor used.

TIME OUT

AMA fails because of noisy measuring signals. Retry until AMA is successfully completed. Please note that repeated AMA runs may heat the motor to a level where the stator resistance is increased.

INTERRUPTED BY USER

AMA has been interrupted by the user.

INTERNAL FAULT

An internal fault has occurred in the drive. Contact Trane service department.

LIMIT VALUE FAULT

The parameter values found for the motor are outside the acceptable range within which the drive is able to work.

MOTOR ROTATES

The motor shaft is rotating. Make sure that the load is not able to make the motor shaft rotate while the AMA is being performed. Then start AMA all over.

ALARM 31 MISSING MOT.PHASE V

Motor phase V, as indicated by the letters on the output terminal block is missing or has a high impedance.

Remove power to the drive and check motor phase V.

ALARM 32 MISSING MOT.PHASE W

Motor phase W, as indicated by the letters on the output terminal block is missing or has a high impedance.

Remove power to the drive and check motor phase W.

WARNING/ALARM 34 HPFB COMM. FAULT

The serial communication on the communication option card is not working.

WARNING 35 OUT FREQ RNG/ROT LIM

This warning will occur if the output frequency has reached its Output Frequency Low Limit , parameter 201, or Output Frequency High Limit, parameter 202. If the drive is in Closed Loop, parameter 100, the

warning will show in the display.

ALARM 37 GATE DRIVE FAULT

An output IGBT or the power card is defective. Contact the Trane service department.

WARNING 62

FOUT > FHIGH

The output frequency is higher than parameter 224, Warning: High

Frequency.

Auto Optimization Warnings 39 through 42

Automatic motor adaptation has stopped, because some parameters have probably been improperly set, or the motor used in too large or small for AMA to be carried out.

A choice must be made by pressing CHANGE DATA and choosing Continue + OK or Stop + OK.

If parameters need to be changed, select Stop, change the parameters and run AMA again.

WARNING 39 CHECK PAR. 104, 106

Parameters 104, Motor Frequency, or 106, Rated Motor Speed, have probably not been set correctly. Correct the setting and run AMA again.

WARNING 40 CHECK PAR. 103, 105

Parameter 103 Motor Voltage, or 105 Motor Current, has not been set correctly. Correct the setting and run AMA again.

WARNING 41 MOTOR TOO BIG

The motor used is probably too large for AMA to be carried out. The setting in parameter 102 Motor Power, may not match the motor. Check the motor and select Continue or [STOP].

WARNING 42 MOTOR TOO SMALL

The motor used is probably too small for AMA to be carried out. The setting in parameter 102 Motor Power, may not match the motor. Check the motor and select Continue or [STOP].

ALARM 60 EXTERNAL FAULT

Terminal 27, parameter 304, Digital Inputs, has been programmed for a Safety Interlock and is a logic 0.

WARNING 61 FOUT < FLOW

The output frequency is lower than parameter 223, Warning: Low Frequency.
