When Pr.08.17 is set to 1, the acceleration and deceleration will operate with full voltage.
During constant speed operation, it will auto calculate the best voltage value by the load power
for the load. This function is not suitable for the ever-changing load or near full-load during
operation.
The max. energy saving is in the stable load output. At this moment, the output voltage is
almost 70% of the rated voltage.

The rated voltage of the motor is usually 230V/200VAC 50Hz/60Hz and the input voltage of
the AC motor drive may vary between 180V to 264 VAC 50Hz/60Hz. Therefore, when the AC
motor drive is used without AVR function, the output voltage will be the same as the input
voltage. When the motor runs at voltages exceeding the rated voltage with 12% - 20%, its
lifetime will be shorter and it can be damaged due to higher temperature, failing insulation and
unstable torque output.
AVR function automatically regulates the AC motor drive output voltage to the Maximum
Output Voltage (Pr.01.02). For instance, if Pr.01.02 is set at 200 VAC and the input voltage is
at 200V to 264VAC, then the Maximum Output Voltage will automatically be reduced to a
maximum of 200VAC.
