Chapter 4 Parameters|
4-108 Revision June 2008, 04EE, SW--PW V1.11/CTL V2.11
This parameter should be used in conjunction with Pr.08.15.
For example: If Pr.08.15 is set to 10 and Pr.08.16 is set to 600s (10 min), and if there is no
fault for over 600 seconds from the restart for the previous fault, the auto reset times for restart
after fault will be reset to 10.
08.17 Automatic Energy-saving

Output Frequency
During auto-energy saving
operation is the output
voltage lowered as much
as possible to keep the load.
The output voltage is maximally
lowered to 70% of the normal
output voltage
08.18 Automatic Voltage Regulation (AVR)
Factory Setting: 0
Settings 0 AVR function enabled
1 AVR function disabled
2 AVR function disabled for deceleration
3 AVR function disabled for stop
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.
