Condition: RST power cable is loose or there is no power. The default setting of
AL022 is a warning. To set AL022 as an alarm, you can set P2.066 [Bit 12].
Cause: RST leak phase.
Check if the RST power cable is loose or there is no power. This alarm occurs when
the 1.5 kW (or below) ASDA-A3 servo drive is not connected to the three-phase
power supply. For 2 kW (or above) ASDA-A3 servo drives, the alarm occurs when
one single phase is not connected to the power supply. Correctly connect the power
to the servo drive. If the issue persists, send your ASDA-A3 servo drive back to the
distributor or contact Delta.
