N/A

AL02C Servo drive overload

Condition: servo drive is overloaded.

Cause:

Trigger condition

and cause

1. The load is over the rated range and the servo drive is in a continuous

overload condition.

2. Improper setting for the gain parameters or the motion profile of the control

system.

3. Motor wiring error.

4. The encoder is damaged or malfunctioning.

Checking method

and corrective

action

How to clear the

alarm?

1. Set P0.002 = 55 to monitor the current feedback. Check if the motor current

exceeds the rated output current of the servo drive for a long period of time.

2. (a) Check if there is any mechanical vibration. If so, properly adjust the gain

parameters.

(b) Set a higher acceleration / deceleration time constant or a lower target

speed.

3. Check if the wiring of the motor power cable and encoder cable is correct.

4. Replace the encoder.
