AL086 Regenerative resistor overload
Trigger condition
and cause
Check the the motor power cable and its connector.
1.
If metal wire is exposed or the wire is torn, the UVW can short-circuit.
In this case, replace the power cable to avoid a short circuit.
Refer to Chapter 3 Wiring and check the following items:
2.
(a) If you do not use the Delta standard power cable, make sure the UVW
wiring sequence is correct.
(b) Make sure the UVW wiring between the servo drive and motor is correctly
connected.
Check if the analog signal GND is mistakenly connected to another ground
3.
signal (incorrect connection can cause interference). Do not use a common
ground for the analog signal GND and other signal cables. Follow the wiring
instructions in Chapter 3.
DI.ARST
Condition: regeneration control error.
Cause: regenerative resistor is not operating, but the regenerative voltage remains
at 400V for a period of time.
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.
If the issue persists, send your servo drive back to Delta.
DI.ARST
Condition: excessive energy in the capacitor of the servo drive is released to the
regenerative resistor causing overload of the resistor.
Cause:
Incorrect selection of the regenerative resistor or no connection to an external
1.
regenerative resistor.
Incorrect parameter settings for P1.052 and P1.053.
2.
Other energy (such as interference) is input to the servo drive or the input
3.
voltage is higher than the allowable rated voltage.
Malfunction of the servo drive hardware.
