Cause : Torque limit comes when the torque has exceeded the value in 4-16 Torque Limit Motor Mode or the value in 4-17 Torque Limit Generator Mode. 14-25 Trip Delay at Torque Limit can change this from a warning only condition to a warning followed by an alarm.

  • If the motor torque limit is exceeded during ramp up, extend the ramp up time.
  • If the generator torque limit is exceeded during ramp down, extend the ramp down time.
  • If torque limit occurs while running, possibly increase the torque limit.
  • Be sure the system can operate safely at a higher torque.
  • Check the application for excessive current draw on the motor.
