This parameter is only available on 125–500 hp drive controllers.

CAUTION

MOTOR OVERHEATING

• Repeated reset of the thermal state after a thermal overload can result in thermal

stress to the motor.

• When faults occur, promptly inspect the motor and driven equipment for problems

such as locked shaft and mechanical overload before restarting. Also check the

power supplied to the motor for abnormal conditions such as phase loss and phase

imbalance.

Failure to follow these instructions can result in equipment damage.
