How to clear the
alarm?
Condition: an error occurs during regeneration.
Cause:
Wrong regenerative resistor or the external regenerative resistor is not
1.
connected.
P1.053 (regenerative resistor capacity) is not set to 0 when the regenerative
2.
resistor is not connected.
Parameter setting error (P1.052 and P1.053).
3.
Check the connection for the regenerative resistor, re-calculate the value for
1.
the regenerative resistor, and reset the value of P1.052 and P1.053. If you
cannot clear the alarm, send your servo drive back to Delta.
Set P1.053 to 0 if not using a regenerative resistor.
2.
Correctly set the parameters for the regenerative resistor (P1.052) and the
3.
regenerative resistor capacity (P1.053).
DI.ARST
Condition: overload of motor and servo drive.
Cause:
The load is over the rated range and the servo drive is in a persistent overload
1.
condition.
The control system parameter is wrong.
2.
Incorrect wiring of motor and encoder.
3.
Encoder malfunction.
4.
Set P0.002 to 12 to monitor the servo drive status. Check if the average load
1.
rate [%] is continuously over 100%. If so, increase the motor capacity or
reduce the load. Refer to Appendix A Specifications for more detail.
(a) Check if there is any mechanical vibration.
2.
(b) Acceleration / deceleration constant is set too high.
Check if the wiring of UVW and the encoder cables is correct.
3.
Send your servo drive back to the distributor or contact Delta.
