Motor FLA Requirements The front of the SMC controller contains a dial which is used for setting the
actual FLA of the motor. The label is designed to accommodate motors
connected in the LINE or DELTA mode. To determine the proper setting, look
at the motor’s nameplate and set the dial accordingly. The dial setting can be
modified depending on the service factor of the motor.

Motor Overload Trip Curves
The trip class should be set according to the motor’s maximum permissible locked
rotor time or the general thermal capabilities. Consult the motor manufacturer
for recommendations on setting the trip class.
