DI.ARST
Condition: RST power cable is loose or there is no power. The error type of AL022
is a warning by default. To set AL022 as an alarm, you can set P2.066 [Bit 12] to 1.
Cause: RST power error.
Check if the RST power cable is loose or there is no power. For 1.5 kW (or below)
ASDA-A3 servo drives, this alarm occurs when all three phases are not connected
to the power supply. For 2 kW (or above) ASDA-A3 servo drives, this 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 servo drive back to the
distributor or contact Delta.
DI.ARST
Early overload warning.
Check if the motor is overloaded and refer to the corrective actions for AL006
1.
for troubleshooting.
Check if the value of P1.056 (Motor output overload warning level) is set too
2.
low. If so, set the value higher, or set the value greater than 100 to disable the
warning function.
DI.ARST
Condition: the magnetic field of the encoder U, V, W signal is in error.
Cause: the initial magnetic field of the encoder is in error (magnetic field of the
encoder U, V, W signal is in error.)
Check if the motor is properly grounded. Make sure the ground end (green) of
1.
the power cable is grounded to the servo drive heat sink.
Check if the connection for the encoder signal cable is normal. Make sure the
2.
encoder signal cable is separated from the power supply or any high-current
cables to avoid interference.
Use shielded cable for the encoder cable. Pull out the wire mesh and have it
3.
correctly grounded.
