AL005 Regeneration error

Condition: an error occurs during regeneration.

Cause:

Trigger condition

and cause

1. Incorrect selection of the regenerative resistor or no connection to an external

regenerative resistor.

2. P1.053 (Regenerative resistor capacity) is not set to 0 when the regenerative

resistor is not connected.

3. Incorrect parameter settings for P1.052 and P1.053.

1. Check the connection for the regenerative resistor, re-calculate the value for

the regenerative resistor, and correctly set the values of P1.052 and P1.053.

Checking method

If the issue persists, send your servo drive back to Delta.

and corrective action 2. Set P1.053 to 0 if not using a regenerative resistor.

3. Correctly set the regenerative resistor value (P1.052) and the regenerative

resistor capacity (P1.053).

AL006 Overload

Condition: overload of motor and servo drive.

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 parameter settings.

3. Incorrect motor wiring.

4. Encoder is in error.

1. Set P0.002 to 12 for monitoring if the average load rate [%] is continuously

over 100%. If so, increase the motor capacity or reduce the load. Refer to

Appendix A for Graph of load and operating time.

Checking method 2. Check if there is any mechanical vibration or the setting for acceleration or

and corrective action

deceleration is too drastic.

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

4. Send the motor back to the distributor or contact Delta.
