Pr.07-20 determines AC motor drive stop method. When the multi-function input terminal is set to
10 or 18 and is activated, the drive will stop according to the setting in Pr.07-20.
Auto Energy-saving Operation
Factory Setting: 0
Settings 0: Disable
1: Enable
When Pr.07-21 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.
When the output frequency is constant, i.e. constant operation, the output voltage will auto
decrease by the load reduction. Therefore, the drive will operate with min. power, multiplication of
voltage and current.

Energy-saving Gain
Factory Setting: 100
Settings 10~1000%
When Pr.00-19 is set to 1, this parameter can be used to adjust the gain of energy-saving. The
factory setting is 100%. If the result is not good, it can adjust by decreasing the setting. If the
motor oscillates, it should increase the setting.
Auto Voltage Regulation(AVR) Function
Factory Setting: 0
Settings 0: Enable AVR
1: Disable AVR
2: Disable AVR during deceleration
The rated voltage of the motor is usually 220V/200VAC 60Hz/50Hz 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 motor rated voltage.
