Increase the starting torque (Pr. 0)
Set this parameter when the motor with a load does not rotate, an alarm OL is output, resulting
in an inverter trip due to OC1, etc.

Example
쑴
When the motor with a load does not rotate, increase the Pr. 0 value 1% by 1% unit by look-
ing at the motor movement. The guideline is for about 10% change at the greatest.
