Servo Motor Overheat (Estimated)

What does 400 mean?

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.

• 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.

1. 1

   Evaluate the motor's duty cycle, load, and speed profile; reduce operating severity if possible.

2. 2

   Verify ambient temperature around the motor does not exceed specified limits.

3. 3

   If the alarm recurs after the motor has cooled, replace the motor or servo amplifier.
