Set the motor speed higher to shorten the duration of the occurrence of
1.
blocked rotor.
Check if the mechanical part connected to the motor is working normally.
2.
Check if the wiring of the motor power cable and encoder cable is correct.
3.
Send your servo motor back to the distributor or contact Delta.

DI.ARST
Condition: when the motor hits the device, the torque reaches the value set by
P1.057 and the duration exceeds the time set by P1.058.
Cause:
Check if the protection function of motor hard stop (P1.057) is enabled.
1.
If so, set P1.057 to 0.
Check if the value set by P1.057 is too low and the time set by P1.058 is too
2.
short. Set P1.057 according to the actual torque. If P1.057 is set to low, it may
lead to malfunction; if P1.057 is set to high, it may lose the protection function.
Cycle power on the servo drive to operate the motor. Then, check if the alarm
occurs again. If the issue persists, replace the encoder.
DI.ARST
Condition: incorrect wiring of the motor power cable (U, V, W) and ground wire
(GND).
Cause: incorrect wiring of the power cable (U, V, W) and ground wire (GND). The
switch for wiring error detection is set by P2.065 [Bit 8], which is enabled by
default.
Check if the wiring of the motor power cable (U, V, W) and ground wire (GND) is
correct. Follow the instructions in this user manual for correct wiring and proper
grounding.
Cycle power on the servo drive.
Condition: abnormal vibration occurred in the encoder.
Cause: the internal signal or mechanical part of the encoder is abnormal, so the
encoder returns an error signal.
