Preface

Thank you for choosing DELTA’s high-performance VFD-F Series. VFD-F Series are

manufactured by adopting high-quality components, material and incorporating the latest

microprocessor technology available.

 Getting Started

This manual will be helpful in the installation, parameter setting, troubleshooting, and daily

maintenance of the AC motor drives. To guarantee safe operation of the equipment, read

the following safety guidelines before connecting power to the AC drives. Keep this

operating manual handy and distribute to all users for reference.

WARNING

Always read this manual thoroughly before using VFD-F series AC Motor Drives.

DANGER!

or disconnect wires and connectors while power is applied to the circuit. Maintenance must be performed by qualified technicians.

CAUTION! There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. To avoid damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages even

if the power has been turned off. To avoid personal injury, do not remove the cover of the AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there are live components exposed within the AC drive. Do not touch these live parts.

CAUTION! Ground the VFD-F using the ground terminal. The grounding method must

comply with the laws of the country where the AC drive is to be installed. Refer to Basic Wiring Diagram.

DANGER! The AC drive may be destroyed beyond repair if incorrect cables are connected

to the input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.

CAUTION! The final enclosures of the AC drive must comply with EN50178. (Live parts

shall be arranged in enclosures or located behind barriers that meet at least the requirements of the Protective Type IP20. The top surface of the enclosures or barrier that is easily accessible shall meet at least the requirements of the Protective Type IP40). (VFD-F series corresponds with this regulation.)

CAUTION! The rated voltage for the AC motor drive must be ≤ 240V for 230V models (≤

480V for 460V models) and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models)

CAUTION! Heat sink may heat up over 70oC (158oF), during the operation. Do not touch

the heat sink.

AC input power must be disconnected before any maintenance. Do not connect

3.5 Wiring Notes:

CAUTION: Do not connect the AC power to the U/T1, V/T2, W/T3 terminals, as it

PLEASE READ PRIOR TO INSTALLATION.

will damage the AC drive.

WARNING: Ensure all screws are tightened to the proper torque rating.

3. During installation, follow all local electrical, construction, and safety codes for the

country the drive is to be installed in.

4. Ensure that the appropriate protective devices (circuit breaker or fuses) are connected

between the power supply and AC drive.

5. Make sure that the leads are connected correctly and the AC drive is properly grounded.

(Ground resistance should not exceed 0.1Ω.)

6. Use ground leads that comply with AWG/MCM standards and keep them as short as

possible.

7. Multiple VFD-F units can be installed in one location. All the units should be grounded

directly to a common ground terminal. The VFD-F ground terminals may also be

connected in parallel, as shown in the figure below. Ensure there are no ground loops.

Forward running

8. When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor

terminals U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclockwise (as

viewed from the shaft ends of the motor) when a forward operation command is received.

To reverse the direction of motor rotation, switch over any of the two motor leads.

9. Make sure that the power source is capable of supplying the correct voltage and

required current to the AC drive.

10. Do not attach or remove wiring when power is applied to the AC drive.

11. Do not inspect components unless inside “CHARGE” lamp is turned off.

12. Do not monitor the signals on the circuit board while the AC drive is in operation.

3-16

VFD-F Series

13. For the single-phase rated AC drives, the AC power can be connected to any two of the

three input terminals R/L1, S/L2, T/L3. Note: This drive is not intended for the use

with single-phase motors.

14. Route the power and control wires separately, or at 90°angle to each other.

15. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close

as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

16. If the AC drive is installed in the place where a load reactor is needed, install the filter

close to U/T1, V/T2, W/T3, side of AC drive. Do not use a Capacitor or L-C Filter

(Inductance-Capacitance) or R-C Filter (Resistance-Capacitance), unless approved by

Delta.

17. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with sensitivity

of 200mA, and not less than 0.1-second detection to avoid nuisance tripping.

18. To improve the input power factor, to reduce harmonics and provide protection from AC

line disturbances (surges, switching spikes, short interruptions, etc.), AC line reactor

should be installed when the power supply capacity is 500kVA or more.

19. There are highly sensitive MOS components on the printed circuit boards. These

components are especially sensitive to static electricity. To prevent damage to these

3.6 Motor Operation Precautions

1. When using the AC drive to operate a standard 3-phase induction motor, notice that the

energy loss is greater than for an inverter duty motor.

2. Avoid running a standard induction motor at low speed. Under these conditions, the

motor temperature may rise above the motor rating due to limited airflow produced by

the motor’s fan.

3. When the standard motor operates at low speed, the output load must be decreased.

4. If 100% output torque is desired at low speed, it may be necessary to use a special

“inverter-duty” rated motor.

5.2 Group 1: Basic Parameters

01 - 00 Maximum Output Frequency Factory Setting: 60.00

Settings 50.00~120.00Hz

 This parameter determines the AC drives maximum output frequency. All master frequency

commands set by the keypad or analog inputs are limited by this parameter. The analog

commands (AVI, ACI1 and ACI2) may be scaled to correspond to the output frequency

range. (Please refer to 04-09~04-20.)

01 - 01 Maximum Voltage Frequency (Base Frequency) Factory Setting: 60.00

Settings 0.10~120.00 Hz

 This parameter sets the frequency, where the maximum output voltage (Pr. 01-02) will be

reached. The output frequency may exceed this setting, but the output voltage doesn’t

increase beyond this point. This parameter should be set according to the rated frequency

of the motor as indicated on the motor nameplate.

 If this parameter setting is smaller than the rated frequency of the motor, nuisance over

current faults or damage to the AC drive may occur.

 If this parameter setting is greater than the rated frequency of the motor, the motor will

encounter torque loss.

01 - 02 Maximum Output Voltage Factory Setting: 220.0/440.0

Settings 230V series: 0.1 ~ 255.0V

460V series: 0.2 ~ 510.0V

 This parameter determines the Maximum Output Voltage of the AC drive. This parameter

setting should be set according to rated voltage of the motor as indicated on the motor

nameplate. If rated voltage of the motor is 440V, this parameter must be set to 440V. If rated

voltage of the motor is 380V, this parameter must be set to 380V.

 If this setting is greater than the rated voltage of the motor, nuisance over current faults or

damage to the AC drive may occur.

01 - 03 Mid-point Frequency Factory Setting: 1.50

Settings 0.10~120.00 Hz

 This parameter sets the Mid-point Frequency of the V/f curve.

 This parameter must meet the following argument. Pr.1-01 >= Pr.1-03 >= Pr.1-05.

5-4

VFD-F Series

01 - 04 Mid-point Voltage Factory Setting: 5.5/11.0

Settings 230V series: 0.1 ~ 255.0V

460V series: 0.2 ~ 510.0V

 This parameter sets the Mid-point Voltage of the V/f curve.

 This parameter must meet the following argument. Pr.1-02 >= Pr.1-04 >= Pr.1-06.

01 - 05 Minimum Output Frequency Factory Setting: 1.50

Settings 0.10~20.00 Hz

 This parameter sets the Minimum Output Frequency of the AC drive. This parameter must

be lower than or equal to the Mid-point frequency

01 - 06 Minimum Output Voltage Factory Setting: 5.5/11.0

Settings 230V series: 0.1 ~ 50.0V

460V series: 0.2 ~100.0V

 This parameter sets the Minimum Output Voltage of the AC Drive. The parameter must be

lower than or equal to the Mid-point Voltage.

01 - 07 Upper Bound Frequency Factory Setting: 60.00

Settings 0.00~120.00 Hz

 This parameter will limit the maximum output frequency of AC drive. If slip compensation

(Pr.07-02~07-05) or feedback control (Pr.10-00~10-09) are enabled, the output frequency

of AC drive may exceed the Master Frequency Command, but it will continue to be limited

by this parameter setting.

01 - 08 Lower Bound Frequency Factory Setting: 0.00

Settings 0.00~120.00 Hz

 This parameter will limit the minimum output frequency. Any Master Frequency Command

below Pr.1-08, will result in an output equal to Pr.1-08.

 Upon a start command, the drive will accelerate from Pr.1-05 Minimum Output Frequency

to the Master Frequency Command point.

 The Lower Bound Frequency setting must be smaller than the Dwell Frequency

(Pr.11-08>=01-08). If lower bound frequency setting is greater than the Dwell Frequency,

the AC drive will equalize the two settings to the Lower Bound point.

01 - 18 JOG Deceleration Time

Factory Setting: 10.0/60.0

Settings 0.1~3600.0 Sec Unit: 0.1sec

 Acceleration time is the time required for the AC drive to ramp from 0 Hz to its Maximum

Output Frequency (Pr.1-00). Deceleration time is the time required for the AC drive to

decelerate from Maximum Output Frequency (Pr.1-00) down to 0 Hz.

 An Acceleration or Deceleration time that is too quick, may cause the AC drives protection

features to enable (over-current stall prevention during Accel 06-01 or over-voltage stall

prevention 06-00). If this occurs, the actual Accel/Decel time will be longer than this setting.

 Warning: An acceleration or deceleration that is too quick, may cause excess loads on the

AC drive and may permanently damage the drive.

 If you want to decelerate the AC drive in short time period, we recommend to add an

external brake module and brake resistor.

 You can set 1

to 4th Accel/Decel time via multi-function input terminals 04-00 to 04-07.

5-6

VFD-F Series

Factory Setting: 6.00

01 - 19 JOG Frequency

Settings 0.0 Hz~120.00 Hz Unit: 0.1sec

 When the JOG function is to be utilized, users need to use the multi-function input terminals

(Pr. 04-00 to 04-07 set to 07) or the JOG key on keypad. Once a JOG command is initiated,

the AC drive will accelerate from the Minimum Output Frequency (Pr.01-05) to the JOG

frequency (Pr.01-19).

 The accel/decel time of the JOG operation is determined by the JOG accel/decel speed

(Pr.01-17 and 01-18).

 When the drive is in operation, the JOG command is disabled.

01 - 20 S Curve Delay Time in Accel Factory Setting: 0.00

01 - 21 S Curve Delay Time in Decel

Settings 0.00~2.50sec

 These parameters enable the S curve. The longer the S curve time period the smoother the

transition between speeds.

Factory Setting: 1.00

01 - 22 Modulation Index

Settings 0.90~1.20 Unit: 0.1

 This parameter sets the ratio of the Maximum Output Voltage to the input voltage.

 The Maximum Output Voltage (Pr.01-02) is normally limited to the input voltage. With the

Modulation Index parameter, the user is able to increase the output voltage beyond the

incoming line voltage.

 A Modulation Index of 1, defines the Maximum Output Voltage (Pr. 1-02) is equal to the

input voltage.

 A Modulation index of 1.2, defines the Maximum Output Voltage (Pr. 1-02) is 20% higher

than in the input voltage. Please note, the output voltage wave form will be distorted due to

harmonics and may increase torque ripple and noise in the motor.

01 - 23 Accel/Decel Time Unit

Factory Setting: 01

Settings 00: Unit is 1 Sec

01: Unit is 0.1 Sec

02: Unit is 0.01 Sec

 This parameter sets the resolution of accel/decel time (Pr.01-09 to 01-18).

 A high resolution decreases the accel/decel time range as shown in the following chart.

VFD-F Series

 In noisy environments, it would be advantageous to verify the terminal status several times

before executing a new command, nearly eliminating false signals.

 Example: If Pr.04-08 is set to 4, the AC drive will confirm the terminal status (4+1 = 5) 5

times before a change is made. This correlates to an 8~10msec time response from input

command to execution.

 It is not recommended to set this parameter to 00, since interference may cause improper

operation of the AC drive.

 This parameter selects the voltage level for the Over-Voltage Stall Prevention function.

 During decelerations, the DC bus voltage may exceed its maximum allowable value due to

motor regeneration. When this function is enabled, the AC drive will stop decelerating and

maintain a constant output frequency. The AC drive will only resume deceleration when the

voltage drops below the preset value.

 With moderate inertial loads, the over-voltage stall prevention will not occur and the

deceleration time should be equal to Pr.1-10. With high inertial loads, the AC drive will

automatically extend the deceleration time due to the step function shown below. If the

deceleration time is critical for the application, then dynamic brake resistors should be

used.

07 - 02 Full-load Current of Motor

Settings 30~120% Unit: 1

 This parameter selects the full load current of the motor.

 Pr7-02 = (full load motor current / drive rated current)

 Example: If the rated current of AC drive is 150A, full-load current of motor is 120A, then

Pr.7-02 should be set to 80%.

5-36

VFD-F Series

 This parameter is used with slip compensation Pr.7-04 to Pr.7-05 and electronic thermal

relay Pr.6-06 to Pr.6-07. An incorrect setting will cause these functions to not work

incorrectly and may damage the motor and drive.

 The full-load current of the motor must be equal to or less than (but not less than 50%) the

rated current of the AC drive.

Factory Setting: 30%

07 - 03 No-load Current of Motor

Settings 1~99% Unit: 1

 This parameter sets the no-load current of the motor.

Pr.7-03 = (no load current / drive rated current)

Example: If the rated current of the AC drive is 150A and no-load current of the motor is 40A,

then Pr.7-03 should be set to 27%.

 This parameter is used with slip compensation Pr.7-04 and Pr.7-05. An incorrect setting will

cause the function to work incorrectly and may damage the motor and drive.

 If the no-load current of the motor is unavailable, it may be found by running the motor with

no load and reading the current on the keypad display.

07 - 04 Auto Slip Compensation Gain

Factory Setting: 0.0

Settings 0.0~3.0 Unit: 0.1

 This parameter is set to auto slip compensation gain.

 Rotor speed of the motor (output frequency of AC drive) can’t synchronize due to induction

motor characteristic. The difference between synchronization speed and rotor speed is

called slip frequency. Slip frequency is in direct proportion with output torque and output

current. Therefore, slip compensation could make rotor speed and master frequency

command the same according output current (lo).

 The equation of slip compensation is (07-05) X (07-04) X (Io-(07-03)) / ((07-02)-(07-03)). If

rated current of AC drive is 150A, full-load current of the motor is 120A, no-load current is

40A, rated slip frequency is 5Hz and output current of AC drive is 100A. At this time, slip

compensation is (07-04) X 5 X (100-40) / (120-40) = 3.75 X (07-04). If 07-04 is set to 1.0

and the compensation is 3.75. If master frequency command is set to 50Hz and output

frequency is 53.75.

 Output frequency after compensation is limited by 01-07 upper bound frequency. When

using slip compensation, 01-07 should be set to the suitable value.

 When PID feedback control, slip compensation function will be disabled.

5-37

VFD-F Series

 Unsuitable setting value may cause over compensation.

07 - 05 Rated Slip Frequency of Motor

Factory Setting: 0.00

Settings 0.00~20.00Hz Unit: 0.01

 This parameter is to set rated slip of loaded motor. Users need to input rated rotation speed

according to nameplate of loaded motor. If rated frequency of motor is 60Hz, number of

motor poles is 4 and rated rotation speed of motor is 1650rpm. The rated slip frequency of

motor is 60Hz-(1650rpm X 4/120) = 5Hz.

 This parameter has relation with 07-04 slip compensation. To have the best slip

compensation, this parameter must be set correctly. Incorrect setting may cause above

functions disable and even damage the motor and AC drive.

07 - 06 Auto Torque Compensation Gain

Factory Setting: 0.0

Settings 0.0~10.0 Unit: 0.1

 This parameter is to set auto torque compensation gain.

 When motor loading is high, a part of output frequency of AC drive will be absorbed by

impedance of stator winding to make voltage of exciting inductance of motor is not enough.

Therefore, the short of gap magnet field will make a high output current but low output

torque. Auto torque compensation gain could adjust output voltage automatically according

to loading to maintain in a fixed gap magnet of the motor to get the best running situation.

 If the setting of compensation gain is too great, over-exciting magnet will cause the

following situation: output current of AC drive is too great, motor is over-heating or

protection function occurs.

07 - 07 Torque Compensation Gain by Manual Operation

Factory Setting: 0.0

Settings 0.0~10.0 Unit: 1.0

 This parameter determines torque compensation gain by manual operation.

 Torque compensation gain by manual operation won’t refer to the loading situation and

adds compensation voltage on the setting V/f curve. Basically, it just changes V/f curve. It

could be reached by adjusting V/f curve.

Factory Setting: 0.0

Settings 0.00~60.00 Sec Unit: 0.01

 This parameter determines the duration of time that the DC brake current will be applied to

the motor during stopping.

 Motor may be in rotation status after AC drive stops output and can’t in stop status accuracy

when motor is running with external force or itself inertia. After AC drive stops output, this

parameter could output a DC current to produce torque force motor to stop and make sure

the motor has stopped accuracy.

08 - 03 Start-point for DC Brake

 The power system connects to AC drive may occurred momentary power loss by any

probably reason. This function can make AC drive output voltage continuously after power

loss and AC drive won’t stop by power loss.

 If this parameter is set to 01, AC drive will trace from the last frequency before power loss

downward. After output frequency of AC drive and running speed of the motor is

synchronization, it will accelerate to master frequency command. It is recommended to use

this setting if the motor loading has the characteristics of high inertial and low resistance.

 If this parameter is set to 02, AC drive will trace from the Min. frequency upward. After

output frequency of AC drive and running speed of the motor is synchronization, it will

accelerate to master frequency command. It is recommended to use this setting if the motor

loading has the characteristics of low inertial and high resistance.

08 - 05 Maximum Allowable Power Loss Time

Factory Setting: 2.0

Settings 0.1~5.0 Sec Unit: 0.1

 This parameter determines the maximum allowable power loss time. If the power loss time

is less than the time defined by this parameter, the AC drive will execute 08-04 momentary

power loss operation.

 The allowable power loss time is beginning to count time after AC drive displays Lu.

Therefore, actual allowable power loss time will change with loading.

 The allowable power loss time must in the condition that AC drive auxiliary power is working

normally. If auxiliary power is turned off in the allowable power loss time, the actual

allowable power loss time will be shorter than the parameter setting.

start to execute the function of speed search time.

08 - 07 Maximum Speed Search Current

Factory Setting: 110

Settings 30~150% Unit: 1

 This parameter determines maximum current of speed search.

 Maximum speed search current will have influence with synchronization attained time. The

greater this parameter is set, the faster it will be synchronization. But if the parameter

setting value is too great, it may occur over-loaded protection.

 If 08-04 is set to 01: when speed search is from top downward, output frequency is

searched from master frequency command downward. Now output voltage and output

current will be added from zero. When output current is equal to 08-07 setting value, AC

drive output current will retain in a fixed value and output frequency will keep on searching

from top downward. When output frequency and output voltage is overlapped with V/f

setting frequency, AC drive will judge that is synchronization attained and accelerates from

V/f curve to master frequency command.

 If 08-04 is set to 02: AC drive will accelerate according to V/f curve and won’t do any special

treatment.

There is a built-in RS-485 serial interface, marked (RJ-11 jack) on the control terminal block.

The pins are defined below:

1: EV 2: GND 3: SG4: SG+ 5: NC

6: for co mmunication

Each AC drive has a pre-assigned communication address specified by 9-00. The

computer then controls each AC drive according to its communication address.

AC drive can be setup to communicate on Modbus networks using one of the following

modes: ASCII (American Standard Code for Information interchange) or RTU (Remote

Terminal Unit). Users can select the desired mode along with the serial port communication

protocol in 09-04 and 09-05.

Code Description:

ASCII mode:

Each 8-bit data is the combination of two ASCII characters. For example, a 1-byte

data: 64 Hex, shown as ‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex).

Character ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’

ASCII Code 30H 31H 32H 33H 34H 35H 36H 37H

Character ‘8’ ‘9’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’

ASCII Code 38H 39H 41H 42H 43H 44H 45H 46H

RTU mode:

Each 8-bit is the combination of two 4-bit hexadecimal characters. For example, 64 Hex.

3.4 CHK (check sum)

ASCII mode:

LRC (Longitudinal Redundancy Check) is calculated by summing up, module 256,

the values of the bytes from ADR1 to last data character then calculating the

hexadecimal representation of the 2’s complement negation of the sum.

For example, reading 1 word from address 0401H of the AC drive with address 01H.

END 1 CR END 0 LF

01H+03H+04H+01H+00H+01H=0AH, 2’s complement of 0AH is F6H.

RTU mode:

RTU mode uses CRC (Cyclical Redundancy Check) detect value. CRC (Cyclical

Redundancy Check) is calculated by the following steps:

Step 1: Load a 16-bit register (called CRC register) with FFFFH.

Step 2: Excusive OR the first 8-bit byte of the command message with the low order

byte of the 16-bit CRC register, putting the result in the CRC register.

Step 3: Examine the LSB of CRC register.

Step 4: If the LSB of CRC register is 0, shift the CRC register one bit to the right with

MSB zerofilling, then repeat step 3. If the LSB of CRC register is 1, shift the

CRC register one bit to the right with MSB zerofilling, Exclusive OR the CRC

Step 5: Repeat step 3 and 4 until eight shifts have been performed. When this is

done, a complete 8-bit byte will have been processed.

5-54

Step 6: Repeat step 2 to 5 for the next 8-bit byte of the command message.

Continue doing this until all bytes have been processed. The final contents

of the CRC register are the CRC value. When transmitting the CRC value in

the message, the upper and lower bytes of the CRC value must be

swapped, i.e. the lower order byte will be transmitted first.

For example, read 2 words from the to address 2102H of AMD with address 01H.

The CRC register content of last byte from ADR to number of data is F76FH. The

command message is as following. 6FH will transmit before F7H.

CRC CHK Low 6FH

CRC CHK High F7H

The following is an example of CRC generation using C language. The function

takes two arguments:

Unsigned char* data Å a pointer to the message buffer Unsigned char length Å the quantity of bytes in the message buffer

The function returns the CRC values as a type of unsigned integer.

unsigned int crc_chk(unsigned char* data, unsigned char length){

int j;

unsigned int reg_crc=0xFFFF;

while(length--){

reg_crc ^= *data++;

for(j=0;j<8;j++){

if(reg_crc & 0x01){ /* LSB(b0)=1 */

reg_crc=(reg_crc>>1) ^ 0xA001;

}else{

reg_crc=reg_crc >>1;

}

return reg_crc;

3.6 Exception response

The AC motor drive is expected to return a normal response after receiving command

messages from the master device. The following depicts the conditions when no normal

response is replied to the master device.

The AC motor drive does not receive the messages due to a communication error; thus, the AC

motor drive has no response. The master device will eventually process a timeout condition.

The AC motor drive receives the messages without a communication error, but cannot handle

them. An exception response will be returned to the master device and an error message

“CExx” will be displayed on the keypad of AC motor drive. The xx of “CExx” is a decimal code

equal to the exception code that is described below.

In the exception response, the most significant bit of the original command code is set to 1, and

an exception code which explains the condition that caused the exception is returned.

Example of an exception response of command code 06H and exception code 02H:

Settings 0.0-6550.0 Unit: 0.1

 Please refer to 04-09 to 04-20 if this parameter is set to PID feedback control.

10 - 02 PID Feedback Control Method

Settings

00: Negative feedback control

Factory Setting: 00

01: Positive feedback control

 This parameter could set the calculation method of deviation signal during PID feedback

control circuit.

 When this parameter is set to 00: when negative feedback control, the deviation equation is

deviation = target value – detection signal. When increasing output frequency will increase

detection value, this setting should be chose.

5-60

VFD-F Series

 When this parameter is set to 01: when positive control, the deviation equation is deviation

= detection signal – target value. When increasing output frequency will decrease detection

value, this setting should be chose.

10 - 03 Proportional Gain (P)

Factory Setting: 1.0

Settings 0.0~10.0 Unit: 0.1

 This parameter is to set proportional gain (P). This gain determines the response degree of

P controller to feedback deviation. If gain value is large, the response is fast. But if the gain

value is too great, oscillation will occur. If gain value is small, the response is slow.

10 - 04 Integral Time (I)

Factory Setting: 1.00

Settings 0.00~100.00 Sec Unit: 0.01

 This parameter is set to integral gain of I controller. When much integral time is to be set,

the gain of I controller is small and the response is slow. The control ability to external is

poor. When less integral time is to be set, the gain of I controller is large and the response is

fast. The control ability to external is fast.

 If the setting of integral time is too small, output frequency and system may occur

oscillation.

 If integral time is set to 0.00, I controller is closed.

10 - 05 Differential Time (D)

Factory Setting: 0.00

Settings 0.00~1.00 Sec Unit: 0.01

 This parameter is set to D controller gain. This gain determines D controller to the response

of change of deviation. Suitable differential time could decrease overshoot of P and I

controller. The oscillation will be attenuation and steady quickly. But if much differential time

is to be set, it may cause system oscillation.

 Interference immunity ability is poor due to differential controller activates to change of

deviation. It’s not recommended to use, especially during interferences.

10 - 06 Upper Bound for Integral Control

Factory Setting: 100

Settings 00~200% Unit: 1

 This parameter could set the upper bound of I controller. In other words, upper bound for

integral control = (01-00) X (10-04) %

10 - 07 Primary Low Pass Filter Time

Factory Setting: 0.0

Settings 0.0~2.5 Sec Unit: 0.1

5-61

VFD-F Series

 This parameter determines primary Low Pass filter time.

 Output frequency of PID controller will filter by primary low pass function. This function

could decrease change of output frequency. A long primary low pass time means filter

degree is high and vice versa.

 Unsuitable primary low pass filter time setting may cause system oscillation.

10 - 08 PID Feedback Signal Range

Factory Setting: 600.0

Settings 0.0~6550.0 Unit:0.1

 This parameter setting could allow the maximum of PID deviation.

 If PID function is normally, it should control the detective value to target value accurately in

the certain time. If AC drive can’t control deviation in the 10-08 setting range during 10-09

setting time, it means PID feedback control is abnormal. The treatment is set as 10-10.

10 - 09 PID Feedback Signal Fault Treatment Time

Factory Setting: 0.0

Settings 0.0~3600.0 Sec Unit: 0.1

 This parameter is to set the detection time of abnormal PID derivative. If PID deviation

detection time is set to 0.0, the function is disabled.

10 - 10 PID Feedback Signal Fault Treatment

Factory Setting: 01

Settings 00: Warn and RAMP stop

01: Warn and COAST stop

02: Warn and keep operating

 This parameter is to set treatment of the abnormal PID deviation.

10 - 11 PID Minimum Output Frequency

Factory Setting: 01

Settings 0: By PID controller

1: By AC drive

 This parameter can decide the source of PID output minimum frequency when AC drive

enters PID sleep process. If it is set to 0, minimum output frequency should be set by PID. If

it is set to 1 and 01-08 is 0, the output frequency is equal to the value of 01-05 setting. If it is

set to 1 and 01-08 is not 0, the output frequency is equal to the value of 01-08 setting.

04: cube curve

 This parameter is to set V/f curve. If this parameter isn’t set to 00, parameter 01-03 and

01-04 will disable.

 Input current of the motor could divide into two orthogonal vectors: magnetic vector and

torque vector. Gap flux, which is produced by Magnetic vector, is in direct proportion with

output voltage of motor. Torque vector produces torque. Torque is in direct proportion with

the result of magnetic vector multiply by torque vector. In theory, if the value of magnet

vector is the same with torque vector (in unsaturated flux condition), the input current is

minimum. If motor loading is unsteady torque loading (loading torque is in direct proportion

with speed. For example, the loading of fan or pump), loading torque is low during low

speed, suitable lower input voltage will decrease input current of magnetic field to lower flux

loss and iron loss of the motor and promote whole efficiency.

 When this parameter is set to high power V/f curve and low frequency torque is lower, it is

not suitable for AC drive to accel/decel quickly. If it needs to accel/decel quickly, it is not

recommended to use this parameter.

03: Fixed amount control (an AC drive runs with 4 motors)

 This parameter is to set an AC drive runs with multiple motors in circulation control mode.

VFD-F Series

 In Pr. 11-01 set for 01 Time Circulation. Starts a motor, runs it for a fixed amount of time Pr.

11-03 stops it (this motor will coast to stop), wait for delay time on Pr. 11-04, then starts the

next motor, runs it for fixed amount of time, etc. Operates like an alternator (also notice that

the Pr.11-03 time includes both the acceleration time and the running time).

 In Pr. 11-02 set to 02 Fixed amount circulation, runs the first motor under PID control, when

this motor can no longer supply the power necessary, it stops output to this motor, waits for

delay time Pr.11-04 and then energizes a contactor for commercial power to run the first

motor, after a short time interval (also the delay time Pr.11-04) , it starts a second motor and

controls it until it cannot handle the load, it then repeats the previous routine. Timer T2 is a

timer that is associated with making sure the drive has exceeded the commercial power

frequency (and T2 needs to be larger than the delay time Pr.11-05 then it will bring on the

next auxiliary motor), and T1 is associated with the sleep process (or T1 is the time that H

from PID is less than 11-08)(and T1 needs to be larger than the delay time Pr.11-07 then it

will either shut down the last auxiliary motor or go into sleep mode if there is no any auxiliary

motor), and reversing out of the sequence IE start 1, 2, 3 then stop 3,2,1.

 When this parameter is set to 02: PID control (group 10) must be set to suitable value.

 When this parameter isn’t set to 00, 03-00 to 03-07 multi-function terminals will

automatically set the corresponding output motor.
