AL007 Excessive deviation of Speed command

Condition: difference between the command speed and the feedback speed

exceeds the allowable range set by P2.034.

Trigger condition

and cause

Cause:

1. A drastic change in the input Speed command.

2. Improper setting of P2.034 (Excessive deviation warning condition of Speed

command).

3. Incorrect wiring of the UVW and encoder cables.

1. Use the signal detector to check if the input analog voltage signal is normal.

If not, adjust the rate of change for input signals or enable the filter function.

Checking method

and corrective action

2.

Check if the value of P2.034 (Excessive deviation warning condition of Speed

command) is set properly.

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

Trigger condition

and cause

2. Gain value is set too low.

3. Torque limit or speed limit is set too low.
