Reduced voltage start

The reduced voltage start function enables you to make the inverter increase the output

voltage gradually when starting the motor.

Set a small value for the reduced voltage start selection () if you intend to increase

the start torque. On the other hand, setting a small value will cause the inverter to

perform full-voltage starting and to easily trip because of overcurrent.
