Condition: an error occurs during regeneration.
Cause:
Incorrect selection of the regenerative resistor or no connection to an external
1.
regenerative resistor.
P1.053 (Regenerative resistor capacity) is not set to 0 when the regenerative
2.
resistor is not connected.
Incorrect parameter settings for P1.052 and P1.053.
3.
Check the connection for the regenerative resistor, re-calculate the value for
1.
the regenerative resistor, and correctly set the values of P1.052 and P1.053.
If the issue persists, send your servo drive back to Delta.
Set P1.053 to 0 if not using a regenerative resistor.
2.
Correctly set the regenerative resistor value (P1.052) and the regenerative
3.
resistor capacity (P1.053).

Condition: overload of motor and servo drive.
Cause:
The load is over the rated range and the servo drive is in a continuous
1.
overload condition.
Improper parameter settings.
2.
Incorrect motor wiring.
3.
Encoder is in error.
4.
Set P0.002 to 12 for monitoring if the average load rate [%] is continuously
1.
over 100%. If so, increase the motor capacity or reduce the load. Refer to
Appendix A for Graph of load and operating time.
Check if there is any mechanical vibration or the setting for acceleration or
2.
deceleration is too drastic.
Check if the wiring of the motor power cable and encoder cable is correct.
3.
Send the motor back to the distributor or contact Delta.
