Condition: RS-485 communication error.
Causes:
1. Improper setting of the timeout parameter (P5.003).
2. Servo drive has not received the communication command for a long
time and has timed out (please refer to P5.003).
1. Check and make sure the value for the communication timeout
parameter is correct.
2. Check if the communication cable is loose or broken and is correctly
wired.
DI.ARST
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) A3 servo drive is not connected to the
three-phase power supply. For 2 kW (or above) 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, please
send your A3 servo drive back to the distributor or contact Delta.
DI.ARST
Early overload warning
1. Check if your servo drive is overloaded and refer to the corrective
actions for AL006 for troubleshooting.
2. Check if the value of P1.056 is set too low. If yes, please increase the
value, which should be over 100 to disable the warning function.
