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 (b036) 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.
