Omron MX2 - Reduced Voltage Start

"B" Group: Fine Tuning Functions Section 3-6
low speed, the inverter may output a frequency that instructs the motor to
rotate in the direction opposite to that specified by the operation command.
3-6-9 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 over-
current.
