04

Linear acceleration and automatic deceleration (Operation by automatic

deceleration time, Pr.10 or Pr.12 acceleration time).

Automatic acceleration, deceleration (Operation by AC drive auto adjustable

control)

If this parameter is set to 04, Accel/Decel time will be equal to or more than

parameter Pr.10 ~Pr.13.

This parameter should not be used when a brake unit is installed.

Pr.102

Auto Voltage Regulation (AVR)

Factory Setting: 00

Settings 00 AVR function enabled

01 AVR function disabled

02 AVR function disabled when stop

03 AVR function disabled for deceleration

AVR function automatically regulates the AC drive output voltage to the Maximum Output

Voltage (Pr.03). For instance, if Pr.03 is set at 200 VAC and the input voltage varies from

200V to 264VAC, then the Maximum Output Voltage will automatically be regulated to 200VAC.

When the AVR function is disabled, the Maximum Output Voltage follows the variations of the

input voltage (180V to 264VAC).

Selecting program value 2 enables the AVR function and also disables the AVR function

during deceleration. This offers a quicker deceleration.

Pr.103

01 Auto tune for R1

02 Auto tune for R1 + No Load testing

For Auto Tune, set Pr.103 to 01 or 02 and press the RUN key. When it is set to 02, motor

should have no load.
