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

safety guidelines before connecting power to the AC motor drive. Keep this operating manual at hand

and distribute to all users for reference.

To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor

drive are to do installation, start-up and maintenance. Always read this manual thoroughly before

using VFD-G series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.

Failure to comply may result in personal injury and equipment damage. If you have any questions,

please contact your dealer.

PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

DANGER!

1. AC input power must be disconnected before any wiring to the AC motor drive is made.

2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power

has been turned off. To prevent personal injury, please ensure that power has been turned off

before opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe

voltage levels.

3. Never reassemble internal components or wiring.

4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the

input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and

W/T3 directly to the AC mains circuit power supply.

5. Ground the VFD-G using the ground terminal. The grounding method must comply with the

laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring

Diagram.

6. VFD-G series is used only to control variable speed of 3-phase induction motors, NOT for 1-

phase motors or other purpose.

7. VFD-G series shall NOT be used for life support equipment or any life safety situation.

WARNI NG!

1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor

drive is easily damaged by high-pressure.

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

are especially sensitive to static electricity. To prevent damage to these components, do not

touch these components or the circuit boards with metal objects or your bare hands.

3. Only qualified persons are allowed to install, wire and maintain AC motor drives.

CAUTION!

1. Some parameter settings will cause the motor to run immediately after applying power.

2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,

high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic

particles.

3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or

electric shock.

4. To prevent personal injury, please keep children and unqualified people away from the

equipment.

5. When the motor cable between the AC motor drive and motor is too long, the layer insulation of

the motor may be damaged. Please use a frequency inverter duty motor or add an AC output

reactor to prevent damage to the motor. Refer to appendix B Reactor for details.

6. The rated voltage for the AC motor drive must be ≤ 480V for 460V models and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models).

8. The AC motor drive, electric welding machine and the greater horsepower motor should be

grounded separately.

9. Use ground leads that comply with local regulations and keep them as short as possible.

10. No brake resistor is built in the VFD-G series, it can install brake resistor for those occasions

that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11. Multiple VFD-G units can be installed in one location. All the units should be grounded directly

to a common ground terminal, as shown in the figure below. Ensure there are no ground

Chapter 4 Parameters|

Group 1: Basic Parameters

01 - 00 Maximum Output Frequency

Settings 50.00~160.00Hz Factory Setting: 60.00

 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 (ACI1 and ACI2) may be scaled to correspond to the output frequency range.

(Please refer to 04-05~04-12.)

01 - 01 Maximum Voltage Frequency (Base Frequency)

Settings 0.10~160.00 Hz Factory Setting: 60.00

 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

Settings 0.2V ~ 510.0V Factory Setting: 440.0

 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

Settings 0.10~160.00 Hz Factory Setting: 3.00

 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.

Revision July 2008, EG03, SW V1.06 4-27

Chapter 4 Parameters|

01 - 04 Mid-point Voltage

Settings 0.2V~510.0V Factory Setting: 11.0

 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

Settings 0.10~20.00 Hz Factory Setting: 3.00

 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

Settings 0.2V~100.0V Factory Setting: 11.0

 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

Settings 0.00~160.00 Hz Factory Setting: 60.00

 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

Settings 0.00~160.00 Hz Factory Setting: 0.00

 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.

Settings 0.1~3600.0 Sec Factory Setting: 10.0/60.0

 Factory setting for 30HP and higher models is 60.0 seconds.

 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 quickly, 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 quickly, 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 adding an external

braking module and braking resistor.

 You can set 1st to 4th Accel/Decel time via multi-function input terminals 04-00 to 04-03.

Revision July 2008, EG03, SW V1.06 4-29

Chapter 4 Parameters|

01 - 19 JOG Frequency Unit: 0.1sec

Settings 0.0 Hz~160.00 Hz Factory Setting: 6.00

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

(Pr. 04-00 to 04-03 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

01 - 21 S Curve Delay Time in Decel

Settings 0.00~2.50sec Factory Setting: 0.00

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

transition between speeds.

01 - 22 Modulation Index Unit: 0.1

Settings 0.90~1.20 Factory Setting: 1.00

 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

 This parameter sets the carrier frequency of PWM output. The factory setting and setting

range depend on the model type.

 When the temperature of the heat sink is greater than its limit, the AC drive will automatic

lower the carrier frequency to avoid over heating the AC drive.

 The Carrier frequency of the PWM output has a signification influence on the electromagnetic

noise, heat dissipation of the AC drive, and the acoustic noise to the motor as shown in the

following chart.

04 - 04 Digital Input Terminal Response Time

Settings 01~20 Factory Setting: 01

 This parameter selects the response time of digital input terminals MI1 to MI4, EF and FWD.

 AC drive will scan the digital input terminals once every 2msec. During each scan the drive will

check the status of each terminal (open or closed).

 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.04-04 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.

 These parameters set analog input value and maximum output frequency (01-00, used in

open-loop control) or the corresponding function of the detection reference value (10-01, used

in PID closed-loop control). They divide output frequency into several sections according to

Pr.04-26 to Pr.04-29. There is an independent gain and minimum output frequency in every

section. We can reduce inferior products and improve working efficiency via parameter

modification. For example, we set frequency via two groups analog input terminals. When the

frequency we set is 0-15Hz and the gain is 50%, the minimum output frequency will be 5Hz;

when the frequency we set is 15-35Hz and the gain is 80%, the minimum output frequency will

be 15Hz; when the frequency we set is 35-50Hz and the gain is 150%, the minimum output

frequency will be 35Hz as the following diagram shows.

 This parameter controls the direction of motion for the Multi-Step Speeds Pr.05-00 to Pr.05-14

during PLC mode. All other direction commands are invalid during the PLC mode.

Note: The equivalent 15-bit number is used to program the forward/reverse motion for each of the 15

speed steps. The binary notation for the 15-bit number must be translated into decimal notation

and then entered.
