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].
Causes:
1. The input voltage of main circuit is lower than the permissible rated
value.
2. No power is supplied to the main circuit.
3. Wrong power input (wrong power system).
1. Check that the voltage wiring is correct and the input voltage for the
main circuit is normal.
2. Cycle the servo drive power and use a voltmeter to check the main
circuit voltage.
3. Use a voltmeter to check if the power system complies with the
specifications. 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]
1. If P2.066 [Bit2] is set to 0, use DI.ARST to clear the alarm after the
voltage is back in the normal range.
2. If P2.066 [Bit2] is set to 1, the alarm is automatically cleared once the
voltage is back in the normal range.
Condition: wrong motor is used with the servo drive.
Causes:
1. Motor combination error (the servo drive connects to the wrong motor.)
2. The encoder is loose.
3. The encoder is damaged.
1. Use the right motor.
2. Check and re-install the encoder connector.
3. If the encoder (motor) is not operating properly, please replace the
motor.
Cycle power on the servo drive.
