Maintenance Manual

VLT® 6000 Series

Adjustable Frequency Drive

03/00 23-6108-00 Revision G

DANGER

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.

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.

NOTE It is responsibility of user or person installing drive to provide proper grounding and branch circuit protection for incoming power and motor overload according to National Electrical Code (NEC) and local codes.

Touching electrical parts may be fatal – even after equipment has

been disconnected from AC line. To be sure that capacitors have

fully discharged, wait 14 minutes after power has been removed

before touching any internal component.

The Electronic Thermal Relay (ETR) in UL listed VLTs provides Class 20 motor overload protection in accordance with NEC in single motor applications, when parameter 117 is set for “ETR TRIP 1”, “ETR TRIP 2”, “ETR TRIP 3”, or “ETR TRIP 4”, and parameter 105 is set for rated motor (nameplate) current.

SOFTWARE VERSION NOTICE: These Operating Instructions are used for all VLT 6000 Series Drives with software version 2.X and all prior versions. The software version number

can be determined from parameter 624,

Software Version

General

(

)

The specific installation instructions may vary depending upon the model of VLT 6000 Series being installed. When this occurs, the model can be identified by a “VLT T ype 6XXX” number . This number can be found on the red nameplate on the outside of the left side of the drive enclosure, or the outside of the right side of a drive with an auxiliary enclosure. A cross reference from the VLT T ype to the Danfoss Graham model number can be found on the next page.

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

Bottom

Clearance

All drives can be mounted with no side clearance. VLT 6350-6550 drives require 25 inches (605 mm) front space for access.

All drives except VLT 6002-6005, 200 to 240 V and VLT 6002-6011, 380 to 460 V must be mounted directly to the wall with no spacers. This is to ensure 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 must be firmly mounted to the back of the drive. See the Cross Reference T able on the next page to convert model numbers to drive type.

Must be mounted

flush to wall

Yes Yes

Sufficient space must be left in front of the drive to provide for door swing on units with a hinged door. 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.

Plenum Mounting

The drive is UL rated for plenum mounting. If the drive is to be mounted in the plenum, allow sufficient access for servicing. All normal clearance, temperature and humidity limitations apply.

Grounding Plate

VLT Type 6002-6005, 200 to 240 V and VLT 6002-6001, 380 to 460 V drives with a NEMA 1 enclosure have a plastic bottom cover with provision for conduit entry . T o meet UL requirements, the metal grounding plate must be in place above the plastic bottom cover. It must be grounded to the chassis, and the conduit grounded to it. 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.

All drives except VL T 6002-6005, 200 to 240 V

and VL T 6002-6011, 380 to 460 V must be

mounted directly to a solid wall with no spacers

between the drive and the wall.

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.

Power Connections

Make all power connections with 75

C rated copper wiring.

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.

T o 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.

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.

O NOT rely on the terminal blocks to provide strain relief.

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.

WARNING

Connecting input power to motor terminals will result in drive failure when power is applied.

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). T erminal 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.

DANGER

For operator safety, it is important to ground drive properly.

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:

CAUTION

Enclosures for larger drives and auxiliary enclosures are made of metal. To avoid getting metal chips into electronics, do not drill any holes after unit has been installed in a vertical position.

Multiple Motors

The VLT 6000 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.

WARNING

When multiple motors are used, VLT 6000 electronic thermal relay cannot be used to provide individual motor protection. A separate motor overload must be supplied for each motor.

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.

CAUTION

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

External DC Bus Connection

T erminals 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.

DANGER

Terminals 88 and 89 will be at approximately 150% of line voltage and remain at high voltage for up to 14 minutes after power has been removed from the drive.

WARNING

Do not connect anything to terminals 88 and 89 without first consulting with Danfoss Graham.

Electrical Installation, Control Wiring

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

Shield control wires, when necessary, to reduce interference from electrical noise by means of a cable clamp at both ends to the metal enclosure of the unit. Connect the shield to earth ground. Very long control wires may create 60 Hz interference. This problem can be solved by connecting one end of the shield to earth with a 0.1 µF capacitor, keeping the leads as short as possible. If this doesn’t solve the problem, disconnect the shield’s connection to earth ground 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.

Switch 1 is not 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

Galvanic Isolation

Galvanic isolation offers protection from electric shock. All control terminals of all VLT 6000 drives, and terminals 1 through 3 of the relay output, offer galvanic isolation as long as the RFI switch (if provided) is in the ON position. The galvanic isolation in the VLT 6000 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 IGBT s, the trigger transformers and optocouplers.

3. The output current Hall effect transducers.

Galvanic Isolation

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.

T o 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.

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 External Fault.

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, T erminal 53, Analog Input V oltage, to Reference. Set Parameter 309, T erminal 53, Min. Scaling, to 0 V. Set Parameter 310, T erminal 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, T erminal 60, Analog Input Curent, to correspond to the purpose of the 4 to 20 mA signal. Set Parameter 315, T erminal 60, Min. Scaling, to 4 mA Set Parameter 316, T erminal 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.

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. Keys for controlling drive operation

5. Indicator lamps

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 select 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 DAT A 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.

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 L and M 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.

red yellow green

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.

AUTO ST ART 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 ST ART key has been pressed.

DANGER

A start signal via digital inputs may cause drive to start at any time. Remove power to drive before working on output wiring, motor or any driven equipment.

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

WARNING

If a minimum speed is set in parameter 201,

Output Frequency Low Limit

and ramp up to this frequency when HAND START is pressed. If drive is already running in Auto Mode when the HAND START key is pressed, it will switch to run in Hand Mode at same speed.

, motor will start

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 Mode

Information is displayed on the LCD by selecting one of three programmable display modes. Pressing the Display Mode key toggles among the displays. When in Mode II, pressing and holding down the Display Mode key accesses an additional mode used to identify the data units the display is showing. (See Navigation Between Display Modes.)

In normal operation, any four meters can be shown continuously on the first and second lines of the display. Parameters 008, 009 and 010 select the three readouts displayed on the top line. Parameter 007, Large Display Readout, selects the meter displayed on line 2. In Display Mode, the + and - keys choose any meter on the LCD.

A list on the next page gives the operating data that can be shown on the three meter readouts for line 1 and the large display (line 2).

The right side of line 2 shows the active setup number and an arrow indicateing the direction of motor rotation. Clockwise indicates forward and counterclockwise indicates reverse. The arrow body disappears if a stop command is given or if the output frequency falls below 0.01 Hz.

Warnings and alarms (fault trips) will also be displayed. For an alarm, “ALARM” and the alarm number is shown in line 2 with an explanation in line 3 or in lines 3 and 4. For a warning, “WARN.” and the warning number is shown in line 2 and an explanation in 3 and/or 4. Both alarms and warnings cause the display to flash.

The line 4 automatically displays the operating status of the drive.

The table below gives the operating data options for the first and second lines of the display .

Manual Initialization of Parameters

It is possible to reset nearly all parameters back to their original default values at once. T o reset the drive parameters to their read only memory default values, remove power from the drive. Press and hold the Display Mode, Change Data and OK keys down while reapplying power. Shortly after power is reapplied, the bottom line of the display will read “Initialized”. After the display stops changing, release the keys. If “Initialized” did not appear, repeat the procedure.

These parameters are not reset by manual initialization:

Parameter 600 Operating hours Parameter 601 Hours run Parameter 602 kWh counter Parameter 603 Number of power-ups Parameter 604 Number of overtemperatures Parameter 605 Number of overvoltages

Initialization can also be done using Parameter 620.

Manual initialization using either this procedure or parameter 620 will reset drive to standard default parameters. Any special programming for application that was performed at factory, during start-up or subsequently, will be lost. If desired parameters have been previously stored in drive’s local control panel (LCP), it may be better to download those parameters from LCP using parameter download functions of parameter 004.

Uploading Parameters

At any time the present parameters may be copied to the local control panel (LCP). This may be useful when setting up multiple drives. It is also useful when it is desired to return to a previous set of parameters. See parameter 004, LCP Copy, for more information.

If the selected parameter’s value is selected from a list, its value can be changed by using the + and - keys.

When the desired value is displayed, press the OK key to accept the new value. If you wish to cancel the change and return to the previously accepted value, press the CANCEL key . If neither OK nor CANCEL is pressed, the new value will be accepted after 20 seconds.

Manually initializing the drive using either the procedure described above or parameter 620, Operating Mode, does not change the values uploaded to the local control panel.

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.

Description of choice:

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

Select Thermistor warning if a warning is desired when the motor thermistor reaches its trip point.

Select Thermistor trip if a fault is desired when the motor thermistor reaches its trip point.

Select ETR Warning 1 through 4, if a warning is desired when the motor is overheated according to the ETR calculations.

The drive can also be programmed to give off a warning signal through one of the digital outputs.

Select ETR Trip 1 through 4 if a fault is desired when the motor is overheated according to the ETR calculations.

Motor Thermal Protection

The motor temperature is calculated on the basis of motor current, output frequency and time. The graph shows the amount of time that the drive can provide a current level to the motor at the rated motor frequency, 20% of rated motor frequency and 200% of rated motor frequency.

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.

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

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, to 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 default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

206 Ramp Up Time (RAMP UP TIME)

CAUTION

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. T oo long of a ramp up time can cause sluggish drive operation. T oo 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.

Description of choice:

Program the desired decel time. T oo long of a ramp down time can cause sluggish operation. T oo 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 For fan applications, factory setting of parameter 207 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]

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

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 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.

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.

If auto ramping is enabled, ramp time can be considerably longer than that set in parameter

207.

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

Function:

The jog frequency is the fixed output frequency at which the drive is running when the jog function is activated.

Jog can be activated via the digital inputs.

Description of choice:

Set the desired frequency.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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 T erminal 53, Analog Input: Reference Parameter 309 T erminal 53, Min. Scaling: 0 V Parameter 310 T erminal 53, Max. Scaling: 10 V

When parameter 210 Reference Type is set to Sum, one of the adjusted Preset References, parameters 21 1 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 21 1, Preset Reference 1, is programmed for 0%.

= 6.0 Hz

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 21 1 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.

-100.00 % to +100.00 % ★ 0.00% of the reference range or external reference

Function:

Four different preset references can be programmed in parameters 21 1 to 214, Preset Reference. The preset reference is stated as a percentage of the reference range or as a percentage of the other external references, depending upon the choice made in parameter 210, Reference T yp e.

216 Frequency Bypass, Bandwidth

(FREQUENCY BYPASS B.W.)

Value:

0 (OFF) to 100 Hz ★ DISABLED

Function:

Mechanical resonance in the driven system sometimes makes it desirable to avoid operation at critical speeds.

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.

The choice of preset references is made by activating terminals 16, 17, 29, 32 or 33, as shown in the table below.

Terminal 17/29/33 Terminal 16/29/32

preset reference msb preset reference lsb

0 0 Preset reference 1 0 1 Preset reference 2 1 0 Preset reference 3 1 1 Preset reference 4

Description of choice:

Set the required preset reference(s) that is/are to be used.

215 Current Limit (CURRENT LIMIT) Value:

0.1 to 1.1 x rated current ★ Depends on the unit

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.

Description of choice:

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

217 Frequency Bypass 1 (BYPASS FREQ. 1) 218 Frequency Bypass 2 (BYPASS FREQ. 2) 219 Frequency Bypass 3 (BYPASS FREQ. 3) 220 Frequency Bypass 4 (BYPASS FREQ. 4) Value:

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.

Description of choice:

Set the required maximum output current.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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.

Function:

WARNING

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 “List of Warnings and Alarms” table in the back of this manual.

Coasting Stop, Inverse is used to release the motor immediately by turning off the output transistors. The motor will coast freely to a stop. Logic ‘0’ implements coasting to a stop.

Reset and Coasting Stop, Inverse is used for activating coasting stop at the same time as reset. Logic ‘0’ implements coasting stop and reset.

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.

T o 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.

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 1 15. Logic ‘0’ implements DC braking. See the DC braking parameters.

Safety Interlock is the same 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.

WARNING

Do not choose software version 1.03. See parameter 624 to determine software version of drive.

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.

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 directrion. 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.

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.

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./

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.

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.

DANGER

Active puts can cause drive to start unexpectedly. Remove power from drive before servicing driven equipment.

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 Hand Start will disable the LCP Hand Start and Auto Start keys.

Hand

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.

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.

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.

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.

308 Terminal 53, Analog Input Voltage (A1 [V] 53 FUNCT.) Function:

This parameter is used to select the required function to be linked to terminal 53.

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.

Thermistor. Selected if a thermistor in the motor stops the drive in case of motor overtemperature. The cutout value is 3 kohm. A Klixon thermal switch may also be connected to this input. 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.

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.

Description of choice:

No operation. Selected if the drive is not to react to signals connected to the terminal.

Reference. Selected to enable change of reference by means of an analog reference signal. If reference signals are connected to several inputs, these reference signals will be summed.

Application Functions

CAUTION

Parameters 400 through 427

Special functions of the drive are set up in this parameter group. This includes the proportional, integral,derivitative 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

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 (AUTOMA TIC X 10) [6] Automatic reset x 15 (AUTOMA TIC X 15) [7] Automatic reset x 20 (AUTOMA TIC X 20) [8]

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.

Description of choice:

Set the desired time before each restart attempt.

When parameter 402, motor may turn forward and reverse a few revolutions even with motor stopped. In highly dynamic pumping processes, it is recommended to disable

402 Flying Start (FLYING START) Value:

★ Disable (DISABLE) [0]

Enable (ENABLE) [1] DC brake and start (DC BRAKE AND STAR T) [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.

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.

If any automatic reset choices are selected, motor can start without warning.

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.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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.

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, W ake-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.”

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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.

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.

405 Wake-up Frequency (WAKEUP FREQUENCY)

CAUTION

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.

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.

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.

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. T o 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.

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

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.

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:

Description of choice:

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

Feedback Signals in Open Loop

In some drives, feedback signals and feedback parameters are only used in closed loop operation. In the VLT 6000, the feedback signals are also active in open loop operation. Although they don’t effect the speed of the drive, they can be displayed on the drive’s meters. Parameters 227 and 228 can set high and low limits for the feedback signals, which can activate warnings.

For open or closed loop operation, the feedback signal is scaled in parameters 413 and 414 Minimum and Maximum Feedback, and the unit displayed is chosen in parameter 415, Process Units.

413 Minimum Feedback (MIN. FEEDBACK) Value:

-999,999.999 to Maximum Feedback, Parameter 414 ★ 0.000

Function:

Parameters 413 Minimum Feedback and 414 Maximum Feedback, are used to scale the feedback signal.

Function:

Selects the unit shown on the feedback display. The selected unit is used if Reference [unit] or Feedback [unit] has

been selected in one of the parameters 007 through 010, as well as in the Display Mode. It will be the unit for Minimum/Maximum Feedback. In Closed Loop, the unit is also used as the unit for Minimum/Maximum Reference and Minimum/Maximum Feedback, as well as Setpoint 1 and Setpoint 2.

Description of choice:

Select the unit for the reference/feedback signal.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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 (Set Point)

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.

The reference range cannot exceed the feedback range.

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 VLT 6000, 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 VLT 6000 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.

Feedback type Terminal Parameters Pulse 33 307 Voltage 53 or 54 308, 309, 310 or

311, 312, 313 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.

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 Parameters Pulse 17 or 29 301 or 305 Voltage 53 or 54 308, 309, 310 or

311, 312, 313 Current 60 314, 315, 316 Preset reference 211, 212, 213, 214 Setpoints 418, 419 Bus reference * 68 and 69 * The bus reference can only be set by serial communication.

T erminals 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.

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.

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 dif ferentiation 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.

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 HV AC 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.

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.

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.

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

1. 1 setpoint and 1 feedback

2. 1 setpoint and 2 feedbacks

3. 2 setpoints and 2 feedbacks

1 Setpoint and 1 Feedback

1 Setpoint and 2 Feedbacks

As above, parameter 418, Setpoint 1, will be added to the remote reference, if a remote reference is used. 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, Feedback Function.

If only one setpoint and one feedback signal are used, parameter 418, Setpoint 1 will be added to the remote reference, if a remote reference is used. The sum of the remote reference, if any, and Setpoint 1 becomes the resulting reference, which will then be compared with the feedback signal.

2 Setpoints and 2 Feedbacks

Parameter 418, Setpoint 1, is the setpoint for zone 1. Feedback for zone 1 is the sum the feedback signals at terminal 53 and Bus Feedback 1. Parameter 419, Setpoint 2, is the setpoint for zone 2.

Parameter 417, Feedback Function, selects whether the drive will attempt to have both feedback signals be at least equal to their respective setpoints (2 zone min.) or be at most equal to their respective setpoints (2 zone max.).

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.

417 Feedback Function (2 FEEDBACK, CALC.) Value:

Minimum (MINIMUM) [0]

★ Maximum (MAXIMUM) [1]

Sum (SUM) [2] Difference (DIFFERENCE) [3] Average (A VERAGE) [4 ] Two-zone minimum (2 ZONE MIN) [5] Two-zone maximum (2 ZONE MAX) [6]

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 sqaure root of the feedback signal.

Function:

This parameter sets the calculation method whenever two feedback signals are used.

Please note that Setpoint 1 is added to the remote reference when Minimum, Maximum, Sum, Difference or Average is selected.

Description of choice:

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

Feedback 1 = Sum of parameter 537, Bus Feedback 1, and the

feedback signal value of terminal 53. Feedback 2 = Sum of parameter 538, Bus Feedback 2, and the

feedback signal value of terminal 54. 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 with Feedback 2.

Please note that Setpoint 1 will be added to the remote reference. 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. Please note that Setpoint 1 will be added to the remote reference.

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.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

418 Setpoint 1 (SETPOINT 1) Value:

Feedback Minimum to Feedback Maximum ★ 0.000

Function:

Setpoint 1 is used to provide the setpoint reference for 1 setpoint PID control and the setpoint for zone 1 in 2 setpoint PID control. External and preset references may be added to its value.

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.

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

419 Setpoint 2 (SETPOINT 2) Value:

Feedback minimum to Feedback maximum ★ 0.000

Function:

Setpoint 2 is used to provide the sepoint reference for zone 2 in 2 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:

If the drive is to reduce the output frequency when the feedback signal increases, select Normal.

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:

The drive will react to a start signal as if in open loop following the acceleration ramp. When the programmed start frequency has been reached, it will change to closed loop operation. This can enable the system to stabilize more quickly.

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.

CAUTION

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

If the drive is to increase the output frequency when the feedback signal increases, select Inverse.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

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 the amount of speed correction that the drive will make in response to the size of the error signal.

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 adjusting this.

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 integration 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 adjusting this.

425 PID Differentiation Time

(PID DIFF. TIME)

Value:

0.00 (OFF) to 10.00 sec. ★ OFF

Function:

When the differentiator is ued, 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 ef fect 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 reduces 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 appliations. See Optimization of the Process Regulator for information on adjusting this.

✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.

Serial Communication for FC Protocol

ADDRESS 1

MASTER

ADDRESS 2

Protocols

All VLT 6000 drives have an RS-485 port which allows controlling the drive by one of three different serial communication protocols. The three protocols, which can be selected in parameter 500, Protocol, are:

● Johnson Controls Metasys N2

● Siemens FLN

● Danfoss 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 VL T 6000 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 Danfoss FC protocol is to be selected, set parameter 500, Protocol to FC protocol .

For further information on operating the drive through N2 or FLN communication, request the N2 or FLN Operator’s Manual from Danfoss Graham.

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.

Contents of a Character (byte)

Each transferred character begins with a start bit. Subsequently, eight data-bits are transferred, corresponding to one byte. Each character is sent with a parity bit to produce even parity (i.e., an even number of binary 1’s in the eight data-bits and the parity bit combined). A character ends with a stop bit and therefore consists of a total of eleven bits.

STX LGE ADR DATA BCC

= Time between characters

Packet Length (LGE)

The packet length is the number of data bytes plus address byte ADR plus data control byte BCC.

bit Parity Bit

Packet Buildup with FC Protocol

Each packet begins with a start character (STX) = 02 Hex, followed by a byte that gives the packet length (LGE) and a byte that gives the drive address (ADR). Next a number of data bytes is sent. The size of the packet is variable, depending upon the packet type. The packet ends with a data control byte (BCC).

- - - - - -

STX LGE ADR Data BCC

Packet Times

The speed of communication between a master and a slave depends on the baud rate. The baud rate of the drive must be the same as the baud rate of the master. Select the baud rate of the drive in parameter 502, Baud Rate.

After a reply packet from the slave, there must be a minimum pause of two characters (22 bits) before the master is able to send another packet. At a baud rate of 9600 baud, there must be a minimum pause of 2.3 msec. After the master has completed the packet, the response time of the slave back to the master is a maximum 20 msec., with a minimum pause of two characters.

Packets with four data bytes have a length of: LGE = 4 + 1 + 1 = 6 bytes

Packets with twelve data bytes have a length of: LGE = 12 + 1 + 1 = 14 bytes

Packets that contain text have a length of 10+n bytes. T en is the fixed characters, while ‘n’ is variable, depending on the length of the text.

Drive Address (ADR)

Two different address formats are used in which the address range of the drive is either from 1 through 31 or from 1 through 126.

1. Address format 1-31

The byte for this address range has the following profile:

76 543210

Bit 7 = 0 (address format 1 through 31 active) Bit 6 is not used Bit 5 = 1: Broadcast, address bits (0 through 4), not used Bit 5 = 0: No Broadcast

Data Character (byte)

The buildup of data blocks depends on the type of packet. There are three types of packets. The packet type applies to both control packets (master→slave) and reply packets (slave→master).

The three types of packets are the following:

1. Parameter block, used for transferring parameters between master and slave. The data block has 12 bytes (6 words) and also contains the process block.

Bit 0 through 6 = 0 Broadcast

The slave sends the address byte back to the master in the reply packet in unchanged form.

Example: A packet is sent to drive address 22 using address format 1 through

Index is used together with the parameter number for read/write access to parameters with an index, such as parameter 615, Error Code.

Index has 2 bytes - a lowbyte and a highbyte. However, only the lowbyte is used. See the example on the following page.

Example - Index:

The first error code (index [1]) in parameter 615, Error code, must be read.

PKE = 1267 Hex (read parameter 615, Error Code). IND = 0001 Hex - Index no. 1.

For a read command, the index must have the following format:

04 00 H

The drive will respond in the parameter value (PWE) block by means of an error code with a value from 1 through 99. See List of Warnings and Alarms to identify the error code.

Parameter Value (PWE)

PKE

IND

PWE

The parameter value block consists of 2 words (4 bytes). Its value depends on the command given (AK). If the master inquires about a parameter value, the PWE block contains no value.

If a parameter value is to be changed by the master (write), the new value is entered in the PWE block and sent to the slave.

If the slave responds to a parameter requirement (read command), the present parameter value is transferred in the PWE block and returned to the master.

If a parameter does not contain a numerical value, but several data selection options, for example parameter 001, Language, where [0] is English and [4] is Spanish, the data value is selected by writing the value in the PWE block. See the example on the following page.

LOW

The drive has two parameters for which a text can be written. These are parameters 533 and 534, Display T ext. See the description in the parameter section of this manual. In order to write a text via the PWE block, the parameter command (AK) must be set to 'F' Hex.

For a write command, the index must have the following format:

05 00 H

Highbyte

Lowbyte

IND

The following data types are supported by the drive:

Data type Description

3 Integer 16 4 Integer 32 5 Unsigned 8 6 Unsigned 16 7 Unsigned 32 9 Text string

Unsigned means there is no sign included in the packet.

Through serial communication, it is only possible to read parameters with data type 9 (text string). In VLT 6000 drives, parameters 621 through 631, Nameplate Data are data type 9. For example, it is possible in parameter 621, Unit Type, to read the unit size and input voltage range.

When a text string is transferred (read), the packet length is variable, since the texts have different lengths. The packet length is stated in the 2nd byte of the packet, called LGE.

In order to read a text via the PWE block, the parameter command (AK) must be set to ‘F’ Hex.

The index character is used to indicate whether the command in question is a read or write command.

Example - Write a parameter value:

Example - Read a parameter value:

Parameter 202, Output Frequency , High Limit, is to be changed to 100 Hz. This value must be remembered after a power failure, so it is written in EEPROM.

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.

Process word

The process word block is divided into two blocks each of 16 bits, which always come in the sequence stated.
