A.2.4 Overload features

Definition of overload protection

The overload protection prevents the motor from overheating.

Causes of overloading

1. The motor's rated torque exceeds the rated range and the operation time is too long.
2. The inertia ratio is too high and the motor frequently accelerates and decelerates.
3. An incorrect connection between the power cable and the encoder wiring.
4. Incorrect servo gain setting causes resonance in the motor.
5. You operate a motor with a built-in brake without releasing the brake.
