Servo Motor Overheat (Estimated)

Fanuc · Alpha i series AC Servo Motor

¿Qué significa 400 ?

The servo motor has overheated, indicated by an estimated temperature exceeding safe operating limits. This suggests that the motor's operating conditions may be excessively severe, leading to thermal stress.

Causas comunes

  • Motor operation conditions are too severe for the motor's thermal capacity (e.g., high duty cycle, excessive load).
  • Ambient temperature around the motor is excessively high.
