Voltage

During the auto energy-saving

operation, it will adjust the output

voltage according to the output

power. The maximum output

voltage can be 30% lower than

the normal output voltage.

Automatic Voltage Regulation (AVR)

Factory Setting: 00

Settings 00 AVR function enabled

01 AVR function disabled

02 AVR function disabled for deceleration



The rated voltage of motor is usually AC220V/200V, 60Hz/50Hz and the input voltage of

AC drive is AC 180V ~ 264V, 50Hz/60Hz. When AC drive runs without AVR function, if

input power is AC 250V and the output voltage to motor will also be AC 250V. The

voltage exceeds 12% ~ 20% of the rated voltage. When motor runs in the higher voltage,

the temperature of motor will be risen, the insulation will be destroyed and the output of

torque will be unsteadily. The motor will be short life if using in these situation for a long

time.



This function will make the output power stay on the rated voltage of motor when input

power exceeds the rated voltage of motor. For example, V/F curve is set to AC

200V/50Hz, input power is AC 200 ~ 264V, the voltage that output to motor will be AC

200V/50Hz and not exceed the setting voltage. If the input power vary between AC 180

~ 200V, the voltage that output to motor will be the same ratio with input power.



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

during deceleration. This offers a quicker deceleration.
