Introduction

This Section describes the applicability of the Manual

The E7 Drive is a Pulse Width Modulated Drive for 3-Phase AC induction motors. This type of Drive is also known as an Adjustable Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD, and Inverter. In this manual, the E7 Drive will be referred to as the “Drive”.

The E7 Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation, including fans, blowers and pumps. A new benchmark for size, cost, performance, benefits, and quality, the E7 includes numerous built-in features such as network communications, H/O/A, PI, parameter storage and copy functions.

The E7 has embedded communications for the popular building automation protocols, Johnson Controls Metasys

Siemens APOGEE

The LCD keypad/operator is equipped with Hand/Off/Auto functions, copy feature, 7 language choices, and 5 lines of display with 16 characters per line. User parameter settings can be recovered at any time via “user initialization”. Optional software allows upload/download, as well as graphing and monitoring of drive parameters from a PC for ease of drive management.

Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes feedback display, inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and pumps for pressure, flow, or temperature regulation.

FLN, as well as Modbus®. An optional LONWORKS® interface card is also available.

 Receiving Checks

Check the following items as soon as the Drive is received.

Table 1.2 Receiving Checks

Item Method

Has the correct model of Drive been delivered?

Check the model number on the nameplate on the right side of the Drive. Reconcile with packing slip and/or order information.

Is the Drive damaged in any way?

Are any screws or other components loose?

If there are any irregularities in the above items, contact the shipping company, the distributor or representative who sold the Drive, or a Yaskawa office immediately.

The E7 is thoroughly tested at the factory. Any damages or shortages evident when the equipment is received must be reported immediately to the commercial carrier that transported the material. Shipping damage is not covered by the Yaskawa warranty. After unpacking and inspecting for damage, verify that internal wire connections have not come loose during shipment by spot checking wire terminations with a screwdriver or the appropriate tool.

E7 Drive storage must be in a clean and dry location. Maintain the factory packaging and provide covering as needed to protect the E7 from construction site dirt, water, debris and traffic prior to and during construction.

Inspect the entire exterior of the Drive to see if there are any dents, scratches or other damage resulting from shipping.

Use a screwdriver or other tool to check for tightness.

Checking and Controlling the Installation Site

Install the Drive as described below and maintain optimum conditions.

WARNING

The Drive heatsink temperature may exceed 158°F (70°C). Therefore, mount the Drive to a surface suitable for high temperature.

 Installation Site

Locate the E7 Drive as close as possible to the motor. Install the Drive under the following conditions in UL Pollution Degree 1 & 2 environments. This excludes wet locations where surfaces may become conductive due to moisture and contaminant loading.

Table 1.5 Installation Site Specifications

Type Ambient Operating Temperature Humidity Plenum Rated

NEMA Type 1 14° F -to- 104°F ( - 1 0 -to- + 40 °C) 95%-RH-or-less-(no-condensation) Yes

Open Chassis 14° F -to- 113°F ( - 1 0 - to -+ 45 °C ) 9 5 % -RH-or-less-(no-condensation) No

Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective covers before operating a CIMR-E7U2030/4055 Drive and smaller in a panel to obtain the 113°F (45°C) ambient operating temperature.

Observe the following precautions when installing the Drive:

• in a clean location which is free from oil mist and dust.

• in an environment where metal shavings, oil, water, or other foreign materials will not get into the Drive enclosure.

• in a location free from radioactive materials.

• in a location free from harmful gasses and liquids.

• in a location free from excessive vibration.

• in a location free from chlorides.

• in a location away from direct sunlight.

• on a non-combustible surface.

 Controlling the Ambient Temperature

To enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperature variations. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature below 113°

F (45°C).

 Protecting the Drive from Foreign Matter

During Drive installation and project construction it is possible to have foreign matter, such as metal shavings or wire clippings, fall inside the Drive. To prevent foreign matter from falling into the Drive, place a temporary cover over the Drive.

Always remove the temporary cover from the Drive before Start-Up. Otherwise, ventilation will be reduced, causing the Drive to overheat.

Install the Drive vertically so as not to reduce the cooling efficiency. When installing the Drive, always provide the following installation clearances to allow normal heat dissipation. For 3HP, 208V/240V (CIMR-E7U22P2 and below) or 2HP, 480V (CIMR-E7U41P5 and below), ensure that the heatsink is against a closed surface to avoid diverting cooling air around the heatsink.

IMPORTANT

Fig 1.8 Drive Installation Orientation and Clearance

1. The same clearance is required horizontally and vertically for both Open Chassis (IP00) and NEMA Type 1 Drives.

2. Always remove the top and bottom protection covers before installing a CIMR-E7U2018/4018 and smaller Drive in a panel. Always provide enough clearance for lifting eye bolts and the main circuit wiring when installing a CIMR-E7U2022/4030 and larger Drive in a panel.

Electrical Installation 2 - 10

Cable Length between Drive and Motor

NOT OK

The E7 should be installed as close as possible to the motor to minimize the length of load side power cable needed between the Drive and the motor.

If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive output current to increase as well. This may affect peripheral devices. To prevent this, reduce the cable length whenever possible, or if necessary, adjust the carrier frequency (set in C6-02) as shown in Table 2.6.

The line side power cables, load side power cables and the control wiring should all be run in a separate conduit. Careful attention to this recommended design practice will avoid many potential motor and Drive related problems.

Table 2.6 Motor Cable Length vs. Carrier Frequency (C6-02)

Motor Cable Length 164 ft. (50m) maximum 328 ft. (100m) maximum More than 328 ft.(100m)

Carrier Frequency 15kHz maximum 10kHz maximum 5kHz maximum

(See the limitations on carrier frequency, based on Drive capacity and model number in Appendix B).

 Ground Wiring

Observe the following precautions when connecting the ground wire:

1. 208-240Vac Drives should have a ground connection with resistance of less than 100Ω.

2. 480Vac Drives should have a ground connection with resistance of less than 10Ω.

3. Do not share the ground wire with other devices, such as motors or large-current electrical equipment.

4. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Drive. Therefore, if the distance between the ground rod and the ground terminal is too long, potential on the ground terminal of the Drive will become unstable.

5. When using more than one Drive, be careful not to loop the ground wire. See Fig 2.2.

The removable Drive control terminal card provides two ground terminals (marked TB3 and TB4) to accept the control wire shield connection. The control wire shield should be connected on this end only, the opposite end should be isolated with electrical tape.

IMPORTANT

Grounding of the E7 enclosure and motor is required for proper system operation.

 Control Circuit Wire Sizes

The auto mode speed reference (speed command) field wiring connection is made to E7 Drive terminals A1 or A2 (signal positive), AC (signal common) and G (shield). Keep this lead length as short as possible to maintain signal quality. Insulated twisted shielded pair wire (2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same conduit as other AC power or control wires. The shield must be connected on this end only, stub and isolate the other end. The A2 signal employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for “0: 0 - 10 VDC” and the E7 control board DIP switch S1-2 must be in the OFF position. (See Fig 2.4).

For remote operation, keep the length of the control wiring to 50m or less. Separate the control wiring from high-power lines (input power, motor leads or relay sequence circuits) to reduce noise induction from peripheral devices.

When setting speed commands (frequency references) from an external speed potentiometer (and not from the Digital Operator), use shielded twisted-pair wires and ground the shield to terminal E(G), as shown in Fig 2.3. Terminal numbers and wire sizes are shown in Table 2.7.

Company: ______________________________________ Signature: ________________________________________

Step

 1. The Drive is thoroughly tested at the factory. The start up person should verify that the drive is free of shipping and

installation damage. Shipping damage is not covered by the Yaskawa warranty. Claims must be filed with the shipping company as soon as possible for any potential recovery via insurance.

 2. Review the E7 User Manual (TM.E7.01) shipped with the Drive.

 3. Verify that the model number and voltage ratings in the purchase order match the nameplate data for each unit.

 4. Location of the Drive is important to achieve proper performance and normal operating life. The unit should be

installed in an area where it is protected from:

Direct sunlight, rain or moisture

Corrosive gases or liquids Vibration, airborne dust or metallic particles

 5. Ensure the Drive is on a vertical surface with adequate space for air circulation (4.75” above and below, 1.2” on each

side). Refer to Fig 1.8.

 6. Verify that the proper branch circuit protection is installed in front of the Drive. Refer to Appendix E - Peripheral

Devices for proper input fuse or circuit breaker sizing.

Start Up 4 - 2

 7. Avoid running input and output wiring in the same conduit.

 8. Avoid routing power wiring near equipment sensitive to electrical noise.

 9. Never allow wire leads to touch metal surfaces. Short-circuit may result.

 10. Never connect AC main power to output terminals U/T1, V/T2 and W/T3.

 11. Never connect power factor correction capacitors or noise filters to the Drive output.

 12. Use 600Vac vinyl-sheathed wire or equivalent. Wire size should be determined considering voltage drop of leads.

Line voltage drop (V) =

x wire resistance (Ω/km) x wire length (m) x current (A) x 10

-3

 13. It is recommended that the motor lead length not exceed 164 feet (50 meters) and motor wiring be run in a separate

conduit from the power wiring. If lead length must exceed this distance, reduce the carrier frequency (See Table 2.6) and consult Yaskawa toll free at 1-800-YASKAWA (927-5292) for other motor protection measures.

 14. Signal and control leads must be separated from main circuit leads (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3).

 15. Determine proper wire size for power and motor leads. Refer to Tables 2.1 and 2.2 for details.

 16. Review proper ground connections for the Drive. Refer to Chapter 2 – Electrical Installation for details. The Drive

must be solidly grounded using the main circuit ground terminal. Ground resistance should be less than 100Ω for a

208-240Vac Drive. Ground resistance should be less than 10Ω for a 480Vac Drive. Select wire size suitable for the size of terminal screw. Make the length as short as possible.

Never ground the drive in common with welding machines, motors or other large-current electrical equipment.

Where several Drives are used, ground each Drive directly or daisy-chain to the ground pole(s).

DO NOT FORM A LOOP WITH THE GROUND LEADS. See Fig 2.2.

 17. Review terminal functions of signal and control circuits. Refer to Table 2.8.

 18. Verify if any customer safety devices are required (e.g. firestat, freezestat, high static pressure).

 19. Record the following motor nameplate information:

Voltage: _____________________Motor Rated Amps: ____________________

 20. Verify that the commercial power supply is within the rated Drive input voltage:

Power Supply: ____________________VAC Drive Input Voltage: ____________________VAC

 21. Verify that the leads in the 3-Phase electric motor conduit box are configured for the proper voltage.

 22. Ensure Motor Rated Current is less than or equal to Drive Output Amps. If multiple motors are being used, make

sure that the Motor Rated Current sum is less than or equal to Drive Output Amp rating. Please note that if multiple motors are being operated from one Drive, each motor must have its own overload and short circuit protection.

Start Up 4 - 3

 23. Wire all necessary power leads to the Drive. DO NOT CONNECT MOTOR TO DRIVE YET.

 24. Wire all necessary ground wires to the Drive.

 25. Wire all necessary control wires to the Drive.

 26. Ensure that the power leads are connected to the R/L1, S/L2 and T/L3 terminals in the Drive.

 27. Tighten all of the three-phase power and ground connections. Please check that all control and signal terminations are

tight.

 28. Inspect the control circuit connections (including the shield) and determine if a motor “safety circuit” is connected.

If normally closed, these contacts may be wired in series with the RUN command contacts, which are between terminals S1 and SN of the Drive. No special programming is required. Refer to Chapter 2 – Electrical Installation (Fig 2.7).

Alternately, these contacts could be wired between terminals S3 and SN as External Fault Inputs, and may be either normally closed or normally open contacts.

 29. Record any other connections to the Drive using the blank terminal connection drawing in Chapter 2 – Electrical

Installation (Fig 2.7) to determine if special programming is required for the following:

•Multi-function Inputs – refer to Appendix A – Parameter List

•Multi-function Outputs – refer to Appendix A – Parameter List

•Multi-function Digital Inputs – refer to Appendix A – Parameter List

•Multi-function Analog Outputs – refer to Appendix A – Parameter List

•Serial Communications – refer to Appendix A – Parameter List

THIS COMPLETES THE DRIVE START UP PREPARATION.

specifies from where the run command will be accepted.

Although the Run Source and the Reference Source (b1-01) are normally taken from the same source (e.g. digital operator, terminals or serial communication), this is not always the case.

To issue a run command from the digital operator: Set b1-02= “0: Operator”, and use the HAND and OFF buttons to start and stop the Drive.

To issue the run command from the terminals: Set b1-02= “1: Terminals”, and select between 2-wire and 3-wire control operation by doing the following:

2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN will be interpreted as a Forward Run command by the Drive. A closure between S2 and SN will be interpreted as a Reverse Run command. If both S1 and S2 are closed, the Drive will stop (decelerate to zero speed) and the digital operator will display an EF (external fault) alarm (Flashing).

Fig 5.2 Wire Control

3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and S2 become Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward/Reverse input for the Drive. When the Forward/Reverse input is open the Drive will run in the Forward direction and when the input is closed, the Drive will run in the Reverse direction.

In 3-wire operation a momentary closure (> 50mS) of S1 will cause the Drive to run provided that S2 is held closed. The Drive will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization (A1-03= “3330: 3-Wire Initial”), then terminal S5 becomes the Forward/Reverse input.

Fig 5.3 Wire Control

To issue a run command via serial communication: Set b1-02= “2: Serial Com” and connect the RS-485/422 serial communication cable to R+, R-, S+, and S- on the removable terminal block. Be sure to use this setting when using the L

 b1-03 Stopping Method

There are four methods of stopping the Drive when the Run command is removed.

Setting Description

0Ramp to Stop (factory default)

1Coast to Stop

2 DC Injection to Stop

3Coast w/Timer

“0: Ramp to stop”: When the Run command is removed, the Drive will decelerate the motor to 0 rpm. The rate of deceleration is determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.

When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5HZ) DC current will be injected in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0 Default), to establish the end point of the ramp. DC injection can be used to insure the motor is at zero rpm prior to the Drive shutting off.

Fig 5.4 Deceleration to Stop

The actual deceleration time can be determined by the following formula

If S-Curve characteristics are specified by the Drive programming, they will add to the total time to stop.

“1: Coast to stop”: When the Run command is removed, the Drive will turn off its output and the motor will coast (uncontrolled deceleration). The friction of the driven equipment will eventually overcome any residual inertia of the system and the rotation will stop.

Once the Minimum Baseblock Time has expired, the Drive will inject DC current into the motor windings to lock the motor shaft. The stopping time will be reduced as compared to Coast to Stop. The level of DC Injection current is set by parameter b2-02 (50% Default). The DC Injection brake time is determined by the set value in b2-04 and the output frequency at the time the Run command is removed.

 b1-04 Reverse Operation

Setting Description

0 Reverse Enabled

1 Reverse Disabled (factory default)

2 Exchange Phase

3 ExchgPhs, Rev Dsbl

For some applications reverse motor rotation is not applicable and may even cause problems (e.g., air handling units, pumps, etc.). Setting parameter b1-04 to 1 or 3 will cause the Drive to ignore any inputs for reverse operation. Setting parameter b1-04 to either 2 or 3 will change the motor shaft rotation when a Forward Run command is given by exchanging the order of the output phasing.

The factory default setting of parameter b1-04 is “1: Disabled”. When b1-04= “1: Disabled”, reverse operation is prohibited and no exchanging of output phasing occurs.

Drive terminal S2 is a dedicated input for reverse Run/Stop.

 b1-07 Local/Remote Run Selection

Setting Description

0 Cycle Extern Run (factory default)

1 Accept Extrn Run

When the Drive is switched between the Local (Hand) mode (the digital operator) to the Remote (Auto) mode (determined by b1-01 and b1-02), there is the possibility that a Run command is already present (i.e. a contact closure between S1 and SN when b1-02= “1: Terminals”). Parameter b1-07 determines whether the Drive will:

Ignore the external Run command until it is removed and re-instated (b1-07= “0: Cycle Extern Run”)

Accept the already present Run command and immediately begin acceleration to the commanded speed

(b1-07= “1: Accept Extrn Run”).

Programming 5 - 8

When switching from local mode to Auto mode when b1-07=“1: Accept Extrn Run” the Drive may start

IMPORTANT

unexpectedly if the Run command is already applied. Be sure all personnel are clear of rotating machinery and electrical connections prior to switching between local mode and Auto mode.

 b1-08 Run Command Selection During Programming

Setting Description

0 Disabled (factory default)

1Enabled

As a safety precaution, the Drive will not normally respond to a Run input when the digital operator is being used to adjust parameters. If it is necessary that external Run commands be recognized even while the Drive is being programmed, set b1-08= “1: Enabled”.

Programming 5 - 9

 b1-11 Drive Delay Time Setting

Setting Range: 0 to 600 Seconds Factory Default: 0 Seconds

If a time is set into parameter b1-11, the Drive will delay executing any run command until the b1-11 time has expired. During Drive delay time execution, the digital operator will display:

Both the ALARM and Run indicators will blink while the Drive waits to execute the Run command.

 b1-12 Hand Frequency Reference Selection

Setting Description

0 Operator (factory default)

1Terminals

When the Drive is put into the HAND mode, by pressing the HAND key while in Operation, the Speed Command will be set via the digital operator by default. If it is desirable to have the Speed Command input from the terminals instead of the digital operator, set b1-12= “1: Terminals”.

IMPORTANT

When the Speed Command is set via the terminals, parameter H3-13 will determine whether analog input terminal A1 or A2 is the Speed Command.

 b2 DC Braking

The DC Braking Group contains parameters associated with the DC injection braking feature. Parameters involving the starting frequency, current level, braking time, and motor pre heat current level are located here.

 b2-01 DC Injection Braking Start Frequency

Setting Range: 0.0 to 10.0 Hz Factory Default: 0.5 Hz

Parameter b2-01 sets the output frequency where the Drive begins DC Injection during Ramp to stop. of the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.

in order to lock the rotor

Parameter b2-01 also determines the output frequency that the Drive must be at or below before a Zero Speed condition is considered true. This affects any digital output configured as a Zero Speed signal (H2-0x= “1: Zero Speed”).

 b2-02 DC Injection Braking Current

Setting Range: 0 to 100% Factory Default: 50%

The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to hold the motor shaft. DC Injection current is set in percentage of Drive rated output current. Drive rated output current is stated on the Drive nameplate.

 b2-03 DC Injection Braking Time at Start

b2-04 DC Injection Braking Time at Stop

Setting Range: 0.00 to 10.00 Seconds Factory Default: 0.00 Seconds

The Drive can be programmed to automatically DC Inject for a predetermined amount of time prior to accelerating to speed (b2-03) and/or at the end of a Ramp to stop (b2-04). Parameter b2-03 can be used to stop a rotating motor prior to attempting acceleration (i.e. a wind milling fan). If DC Injection braking at start or Speed Search is not enabled, attempting to drive a spinning motor may cause nuisance tripping.

Parameter b2-04 can be used to resist any residual motion of the load after the deceleration has finished.

Fig 5.9 DC Injection Braking During Starting and Stopping

Parameter b2-04 also serves the function of affecting the length of time DC Injection to stop (b1-03= “2: DC Injection to Stop”) will occur.

Programming 5 - 11

 b2-09 Motor Pre-Heat Current

Setting Range: 0 to 100% Factory Default: 0%

A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and prevent condensation. Parameter b2-09 determines the percentage of Drive rated output current that will be used for the motor pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions. Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat

(H1-0x= 60). Check with the motor manufacturer to determine the maximum acceptable current level the motor can

Input withstand when stopped. Be sure not to exceed the motor manufacturers recommended level.

 b3 Speed Search

The Speed Search function allows the Drive to determine the speed of a motor shaft that is being driven by rotational inertia. Speed Search will allow the Drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed without first having to bring it to a complete stop. When a momentary loss of supply power is experienced, the Drive output is turned off. This results in a coasting motor. When power returns, the Drive can determine the speed of the coasting motor and start without requiring it to be brought to minimum speed. Speed Search can be programmed to always be active by setting b3-01 or it can be commanded by remote contact closure by setting a digital input.

There are two forms of Speed Search in the Drive, the speed estimation method and the current detection method.

When setting the Drive for remote Speed Search input, via a contact closure, the method of Speed Search

IMPORTANT

is determined by the setting of b3-01. If b3-01= “0: SpdsrchF Disable” then the remote input will initiate speed estimation method, and if b3-01= “2: SpdsrchI Disable”, then the remote input will start the current detection method.

Parameters L2-03 and L2-04 also affect the current detection method of Speed Search operation.

 b3-01 Speed Search Selection

This parameter is effective only when the Drive is given a new “RUN” command.

Setting Description

0SpdsrchF Disable

1SpdsrchF Enable

2 SpdsrchI Disable (factory default)

3SpdsrchI Enable

Speed Estimation: Method (b3-01= 0 or 1) The speed estimation method will calculate the speed using measurements of

residual motor fields. The speed estimation version is bi-directional and will determine both the motor speed and direction. To enable speed estimation Speed Search at start, set b3-01= “1: SpdsrchF Enable”.

If the speed estimation method of Speed Search is to be used, then Auto-tuning must be performed prior to

IMPORTANT

using Speed Search. If the length of cable between the Drive and motor is ever changed after Auto-tuning then Auto-tuning should be performed again.

IMPORTANT

Performing auto-tuning energizes the motor so that identification of key motor characteristics can be determined. Output filters may affect the accuracy of measured characteristics, and/or result in drive damage. Therefore, it may be necessary to remove output filters completely prior to executing tuning procedures. Consult the factory with questions regarding filter compatibility.

inputs

When using the current detection method of Speed Search, parameter b3-02

sets the current level that will determine when the

search is complete and the rotor and output speeds match. When the output frequency is higher than the actual rotor speed the slip causes the current to be high. As the output frequency is lowered, the closer it comes to the rotor speed, the lower the current draw will be. When the output current drops below the level as set in b3-02 (100% = Drive Rated Current) the output frequency stops decreasing and normal operation resumes.

 b3-03 Speed Search Deceleration Time

Setting Range: 0.1 to 10.0 Seconds Factory Default: 2.0 Seconds

Parameter b3-03 sets the deceleration ramp used by the current detection method of Speed Search when searching for the motor’s rotor speed. Even if Speed Search 2 is selected, for Speed Search at start, the time entered into b3-03 will be the time to decelerate from maximum frequency (E1-04) to minimum frequency (E1-09).

 b3-05 Speed Search Delay Time

Setting Range: 0.0 to 20.0 Seconds Factory Default: 0.2 Seconds

In cases where an output contactor is used between the Drive and the motor, extra waiting time is provided after power returns and before Speed Search is performed. This extra time allows for the contactor to operate. When Speed Search at start is used, b3-05 will serve as the lower limit of the Minimum Baseblock Time (L2-03).

 b3-14 Bi-Directional Speed Search Selection

Setting Description

The analog feedback to the Drive for the PI control is via the A2 terminal. The Drive must be programmed (H3-09= “B: PI Feedback”) to use terminal A2 as feedback for the PI functionality of the Drive.

building pressure control is an example. The drive can be programmed to maintain a set differential between two analog signals. If input A2 is configured as a “PI Differential Mode” (H3-09= “16: PI Differential”), then the Drive will maintain a set difference between the measurements read on inputs A1 and A2. This differential setpoint is programmed by parameter (b5-07).

 b5-01 PI Mode

Setting Description

0 Disabled (factory default)

3 Fref+PI

The Drive can be used as a stand-alone PI controller. If PI functionality is selected by parameter b5-01, the Drive will adjust its output to cause the feedback from a transmitter to match the PI setpoint (b5-19). The setting of b5-01 will determine whether PI functionality is disabled (b5-01= “0: Disabled”), enabled (b5-01= “1: Enabled”), or enable with the output of the PI function used to trim a Speed Command (b5-01= “3: Fref+PI”).

 b5-02 Proportional Gain Setting

Setting Range: 0.00 to 25.00 Factory Default: 2.00

The proportional gain will apply a straight multiplier to the calculated difference (error) between the PI Setpoint and the measured transmitter feedback at terminal A2. A large value will tend to reduce the error but may cause instability (oscillations) if too high. A small value may allow to much offset between the setpoint and feedback (See Fig 5.16 below).

 b5-03 Integral Time Setting

Setting Range: 0.0 to 360.0 Seconds Factory Default: 5.0 Seconds

The Integral factor of PI functionality is a time-based gain that can be used to eliminate the error (difference between the setpoint and feedback at steady state). The smaller the Integral Time set into b5-03, the more aggressive the Integral factor will be. To turn off the Integral Time, set b5-03= 0.00.

Fig 5.16 PID Feedback Response Characteristics

Programming 5 - 17

 b5-04 Integral Limit Setting

Setting Range: 0.0 to 100.0% Factory Default: 100.0%

On some applications, especially those with rapidly varying loads, the output of the PI function may have large oscillations. To suppress these oscillations, a limit can be applied to the integral factor by programming b5-04.

 b5-06 PI Output Limit

Setting Range: 0.0 to 100.0% Factory Default: 100.0%

Places a cap on the output of the PI function. Limiting the PI function may help to prevent large overshoots in the Drive’s response to error (the difference between the setpoint and the feedback).

 b5-07 PI Offset Adjustment

Setting Range: -100.0% to +100.0% Factory Default: 0.0%

The PI Offset Adjustment parameter has two different uses. Parameter b5-07 serves different functions depending on whether it is used on a standard PI loop or a Differential PI loop.

Parameter b5-07 causes an offset to be applied to the output of the PI function in a non-Differential PI loop. Every time the PI output is updated, the offset (b5-07) is summed with the PI output. This can be used to artificially kick-start a slow starting PI loop.

If the Drive is configured for Differential PI Regulation (H3-09= “16: PI differential”), then this parameter is the target setpoint for the differential to be maintained between the signal measured on analog input A1 and the signal measured on analog input A2.

 b5-08 PI Primary Delay Time Constant

Setting Range: 0.00 to 10.00 Seconds Factory Default: 0.00 Seconds

Acts as a time based filter that lowers the responsiveness of the PI function, but also makes the function more stable when the setpoint varies rapidly or when the feedback is noisy.

 b5-09 PI Output Level Selection

Setting Description

0 Normal Output (direct acting) (factory default)

1 Reverse Output (reverse acting)

Normally, the output of the PI function causes an increase in motor speed whenever the measured feedback is below the setpoint. This is referred to as direct acting response. However, if b5-09= “1: Reverse Output”, the output of the PI function causes the motor to slow down when the feedback is below the setpoint. This is referred to as reverse acting response.

Setting Range: 0.0 to 25.0 Factory Default: 1.0

Applies a multiplier to the output of the PI function. Using the gain can be helpful when the PI function is used to trim the Speed Command. Increasing b5-10 causes the PI function to have a greater regulating affect on the speed command.

 b5-11 PI Reverse Selection

Setting Description

0 0 Limit (factory default)

1 Reverse

Parameter b5-11 determines whether reverse operation is allowed while using PI control (b5-01≠0). The factory default setting will not allow the Drive to run in reverse. This parameter does not need to be changed from factory default for a majority of HVAC applications. (Refer also to b5-09).

 b5-12 PI Feedback Reference Missing Detection Selection

Setting Description

0 Disabled (factory default)

1Alarm

2Fault

Loss of feedback can cause problems to a PI application. The Drive can be programmed to turn on a digital output whenever a loss of feedback occurs. Feedback Loss Detection is turned on by b5-12. When b5-12= “1: Alarm”, the Drive acknowledges the loss of feedback without stopping or turning on the fault output (MA-MB). If b5-12= “2: Fault”, the Drive coasts to a stop and turns on the fault output if the feedback is determined to be lost.

 b5-13 PI Feedback Loss Detection Level

Setting Range: 0 to 100% Factory Default: 0%

 b5-14 PI Feedback Loss Detection Time

Setting Range: 0.0 to 25.0 Seconds Factory Default: 1.0 Seconds

The Drive interprets feedback loss whenever the feedback signal drops below the value of b5-13 and stays below that level for at least the time set into b5-14. See Fig 5.17 below for timing details.

 b5-16 Sleep Delay Time

Setting Range: 0.0 to 25.5 Seconds Factory Default: 0.0 Seconds

The Sleep Function can be programmed to prevent running the Drive when the PI loop output or the speed command is so low that no usable work is being done and/or equipment damage may result. The Sleep Function can be Enabled by entering a value in parameter b5-15. If the Drive’s output drops below the level set by the Sleep Function Start Level (b5-15) and remains there at least as long as the delay time determined by the Sleep Delay Time (b5-16), then the Drive’s internal Run command drops out and the Drive output ceases. Though the Drive’s output has ceased, all other Drive functions continue. Once the Drive’s theoretical output returns to a level above the Sleep Function Start Level (b5-15) and remains above that level for at least the Sleep Delay Time (b5-16), the internal Run command returns and the Drive output begins again. The b516 Delay Time prevents oscillation about the sleep level.

Note: The sleep function can be used even if the PI function is disabled (b5-01 = “0: Disabled”).

 b5-17 PI Accel/Decel Time

Setting Range: 0.0 to 25.5 Seconds Factory Default: 0.0 Seconds

This is a soft start function that is applied to the PI setpoint analog input. Instead of having nearly instantaneous changes in signal levels, there is a programmed ramp applied to level changes. When changing setpoints the error can be limited by gradually ramping the setpoint through the use of parameter b5-17.

 b5-18 PI Setpoint Selection

Setting Description

0Disabled (factory default)

1Enabled

Programming 5 - 20

In order to use parameter b5-19 as the PI Setpoint, set parameter b5-18= “1: Enabled”. If b5-18= “0: Disabled” the PI Setpoint will either be:

• Modbus Register 06H (If Register 0FH bit 1 is high)

• The active speed command (i.e. Determined by the setting of b1-01). See Table 1 “Setpoint Options”

 b5-19 PI Setpoint Value

Setting Range: (dependant on parameter b5-20) B5-19 Setting Range Example:

b5-20 Setting b5-19 “Setting Range”

0 0 - 60.00

1 0.00 - 100.00

2 0 - 3600

4 0 - 1800

6 0 - 1200

Factory Default: 0.00

Parameter b5-19 is for a PI Setpoint value. When b5-18= “1: Enabled”, the value of b5-19 will take precedent over any other PI setpoint unless the Drive is set up for Differential Feedback, in which case, b5-18 and b5-19 have no affect on the PI function. Displayed units are determined by b5-31, regardless of b5-20 setting. This does not affect the value programmed into the drive.

Example: if b5-20 = 1, b5-31 = 0, then b5-19 will be displayed in “WC: Inches of Water Column The value set in b5-19 will be

in percent feedback.

The PI Setpoint Display Scaling value (b5-20) is a scaling factor that is applied to the monitor display for both the PI Setpoint (U1-38) and the PI Feedback (U1-24) and (b5-19) PI Setpoint. Display text for the units is set by b5-31 PI Unit Selection.

If the monitors seem more natural in terms of percentage, set b5-20= 1. If the monitors are easier to work with when displaying the equivalent synchronous RPM, set b5-20= [the number of motor poles]. If another engineered unit, such a fpm or cfm, is desired, set b5-20= xxxxx where

Programming 5 - 21

For example:

If b5-20= 10425 then at 100% setpoint/feedback the digital operator would display 42.5 for monitor U1-38 or U1-24.

 b5-21 Sleep Source

Setting Description

0 SFS Input (Output of PI block)

1 PI Setpoint (factory default)

2 Snooze

Parameter b5-21 selects the sleep function characteristic action:

When b5-21= “0: SFS Input” the sleep function start level (b5-15) is compared to the Drive’s output (Speed Command after PI block). This is the setting that should be used for open loop or closed loop control.

It is also possible to have the sleep function start level (b5-15) compared to the Drive input or setpoint. For this special application set b5-21= “1: PI Setpoint”.

When b5-21= “2: Snooze” a variation of the sleep function called “Snooze” is enabled, see parameter b5-22 to b5-27.

IMPORTANT

The sleep function can be used even if the PI function is disabled (b5-01= “0: Disabled”).

 b5-22 PI Snooze Level

Setting Range: 0 to 100% Factory Default: 0%

 b5-23 PI Snooze Delay Time

Setting Range: 0 to 3600 Seconds Factory Default: 0 Seconds

 b5-24 PI Snooze Deactivation Level

Setting Range: 0 to 100% Factory Default: 0%

The Snooze Function is a variation on the Sleep Function. The Snooze function must be selected by setting parameter b5-21= “2: Snooze”. Once the Snooze Function is selected, the Drive monitors the output frequency. If the output frequency drops below the PI Snooze Level (b5-22), and stays below that level for at least the PI Snooze Delay Time (b5-23), the Drive output shuts off. This is different from the Sleep Function because it is the feedback that must drop below the PI Snooze Deactivation Level (b5-24) before normal Drive output will begin again. See Fig 5.19 on next page.

 b5-25 PI Setpoint Boost Setting

Once the temporary boost level is reached (or the PI Maximum Boost Time (b5-26) is exceeded), the Drive output shuts off (snoozes) and the intended PI Setpoint returns. From this point on, the Snooze Function operates normally and the Drive output returns when the feedback level drops below b5-24. See Fig 5.19 below.

 b5-27 PI Snooze Feedback Level

Setting Range: 0 to 100% Factory Default: 60%

This is a second method of initiating the Snooze Function. If the PI feedback level exceeds the PI Snooze Feedback Level (b5-27), then the Drive output shuts off. Once the PI feedback drops below the PI Snooze Deactivation Level (b5-24) then normal Drive and PI operation return. Snooze activates if both b5-22 and b5-27 conditions are met. There is no time delay for wake-up.

 b5-28 PI Feedback Square Root Function Activation

Setting Description

0 Disabled (factory default)

1Enabled

If b5-28= “1: Enabled”, the square root of the PI feedback is compared to the PI Setpoint in order to determine appropriate Drive output to properly regulate the system. This is helpful in cases where the measured feedback is pressure but the PI loop needs to regulate flow.

 b5-29 PI Square Root Gain

 b8 Energy Savings

The energy savings function improves overall system operating efficiency by operating the motor at its highest efficiency. This is accomplished by continuously monitoring the motor load and adjusting the motor terminal voltage so that the motor always operates near its rated slip frequency. A motor is most efficient when operating near rated slip conditions.

 b8-01 Energy Savings Selection

Setting Description

0 Disabled (factory default)

1Enabled

When the Energy Savings function is enabled (b8-01= “1: Enabled”), the Drive reduces the output voltage to the motor below the voltage value specified by the programmed V/f pattern whenever the motor load is light. Since torque is reduced during this voltage reduction, the voltage has to return to normal levels when the load returns. The energy savings is realized through improved motor efficiency. The reduced output voltage causes increased rotor slipping even with a light load. A motor is most efficient when operating fully loaded (i.e. operating at rated slip).

 b8-04 Energy Saving Coefficient Value

Setting Range: 0.0 to 655.0 Factory Default: Model Dependent

Parameter b8-04 is used in maximizing motor efficiency. The factory setting will be Drive capacity dependant but can be adjusted in small amounts while viewing the kW monitor (U1-08) and running the Drive to minimize the output kW. A larger value typically results in less voltage to the motor and less energy consumption. Too large a value will cause the motor to stall.

 b8-05 Power Detection Filter Time

Setting Range: 0 to 2000 mS Factory Default: 20 mS

The Energy Saving function will search out the lowest output voltage in order to achieve minimum output power usage. Parameter b8-05 determines how often the output power (kW) is measured and the output voltage is adjusted.

 b8-06 Search Operation Voltage Limit

Setting Range: 0 to 100% Factory Default: 0%

Once Energy Savings is enabled and the optimal energy saving coefficient value has been set, the programmer can have the Drive further search out the proper voltage to achieve the lowest output power by making minute changes to the output voltage and measuring the output power every b8-05 ms. Parameter b8-06 sets limits to the range over which the voltage will be adjusted in order to minimize the power output. Settings too large a value may allow the motor to stall if the load is applied abruptly.

If b8-06= 0, then the optimum voltage search operation is disabled (but not Energy Savings itself).

 C1 Accel/Decel

 C1-01 Acceleration Time 1

C1-02 Deceleration Time 1 C1-03 Acceleration Time 2 C1-04 Deceleration Time 2

Setting Range: 0.0 to 6000.0 Seconds Factory Default: 30.0 Seconds

C1-01 (Acceleration Time 1) sets the time to accelerate from zero to maximum speed (E1-04). C1-02 (Deceleration Time 1) sets the time to decelerate from maximum speed to zero. C1-01 and C1-02 are the factory default active accel/decel “pair”. Another accel/decel pair (C1-03 and C1-04) exists that can be activated by a multi-function digital input (H1-0x= 7), or

specified by a switch over frequency as programmed in parameter C1-11.

Note: If fan applications employing duct high pressure safety limit switches, it may be necessary to further adjust the

deceleration time to avoid high pressure limit trips due to damper closure as the system is shut down. (An alternate solution in this situation is to set parameter b1-03 to “Coast to Stop”).

 C1-09 Fast Stop Time

Setting Range: 0.0 to 6000.0 Seconds Factory Default: 10.0 Seconds

A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a special deceleration that can be operated by closing a digital input configured as H1-0x= 15 or H1-0x= 17. A digital input configured as H1-0x= 15 will look for a switch closure before initiating the Fast Stop operation. A digital input configured as H1-0x= 17 will look for the switch opening before initiating the Fast Stop operation.

Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the Drive cannot be re-operated until the deceleration is complete, the Fast Stop input is cleared, and the Run command is cycled.
