Check if the input voltage of the main circuit is within the rated range. If the
2.
issue persists, send your servo drive back to the distributor or contact Delta.
Check the connection for the regenerative resistor, re-calculate the value for
3.
the regenerative resistor, and reset the value of P1.052 and P1.053.
DI.ARST
Condition: main circuit voltage is below the rated value. By default, AL003 is
defined as a warning. To define it as an alarm, set P2.066 [Bit 9].
Cause:
The input voltage of main circuit is lower than the permissible rated value.
1.
No power is supplied to the main circuit.
2.
Wrong power input (wrong power system).
3.
Check that the voltage wiring is correct and the input voltage for the main
1.
circuit is normal.
Cycle the servo drive power and use a voltmeter to check the main circuit
2.
voltage.
Use a voltmeter to check if the power system complies with the specifications.
3.
Check if using the right voltage source or the transformer is connected in series.
AL003 is cleared according to the setting of P2.066 [Bit2]
If P2.066 [Bit2] is set to 0, use DI.ARST to clear the alarm after the voltage is
1.
back in the normal range.
If P2.066 [Bit2] is set to 1, the alarm is automatically cleared once the voltage
2.
is back in the normal range.
Condition: wrong motor is used with the servo drive.
Cause:
Motor combination error (the servo drive connects to the wrong motor).
1.
The encoder is loose.
2.
The encoder is damaged.
3.
Use the right motor.
1.
Check and re-install the encoder connector.
2.
If the encoder (motor) is not operating properly, replace the motor.
3.
Cycle power on the servo drive.
