LED Display LCD Display

Range Off, 1 – 40 (Default class 10)

Description The Motor Overload Class Starting parameter sets the class of the electronic overload when starting. The

starter stores the thermal overload value as a percentage value between 0 and 100%, with 0% representing a

“cold” overload and 100% representing a tripped overload.

The starting overload class is active during Kicking and Ramping when the Independent Starting/Running

Overload (P44 / PFN 13) parameter is set to “On”.

When the Motor Starting Overload Class parameter is set to "Off", the electronic overload is disabled while

starting the motor.

z NOTE: Care must be taken not to damage the motor when turning the starting overload class off or setting

to a high value.

z NOTE: Consult motor manufacturer data to determine the correct motor OL settings.
