11.6 Overload
Features
Definition of overload protection
The overload protection is to prevent the motor in overheat status.
Cause of overload
1) When the motor operates over the rated torque, the operation time is too long
2) The inertia ratio is set too big and frequently accelerate / decelerate
3) Connection error between the power cable and encoder wiring
4) Servo gain setting error and cause resonance of the motor
5) The motor with brake operates without releasing the brake
