Overload Features
Definition of Overload Protection
The overload protection is to prevent the motor from overheating .
Causes of Overload
1) The motor operates over the rated torque and the operation time is too long.
2) The inertia ratio is set to be too big and frequently accelerate/decelerate.
3) Connection error between power cable and encoder wiring.
4) Servo gain setting is in error which causes resonance of the motor.
5) The motor with brake operates without releasing the brake.
