Range OFF, 1 – 40 (Default 10)
Description The Motor Starting Overload Class 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 parameter is set to “ON”.
When the Motor Starting Overload Class parameter is set to OFF, and the Independent
Starting/Running Overload is “ON”, the electronic overload is disabled while starting the motor.
NOTE: Care must be taken not to damage the motor when turning the starting overload class off or
setting to a high value.
NOTE: Consult motor manufacturer data to determine the correct motor OL settings.
