A.2.4 Overload features

Definition of overload protection

The overload protection prevents the motor from overheating.

Causes of overload

1. The motor’s operating torque exceeds the rated range and the operating time is too long.

2. The inertia ratio is too high and the motor frequently accelerates and decelerates.

3. Incorrect wiring of the power and encoder cables.

4. Incorrect servo gain setting causes resonance in the motor.

5. A motor with a built-in brake operates without the brake released.
