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.

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.
