AL031 Motor power cable wiring error / disconnection
Trigger condition
and cause
Condition: incorrect wiring or disconnection of the motor power cable (U, V, W) and
ground wire (GND).
Cause: incorrect wiring or disconnection of the power cable (U, V, W) and ground
wire (GND). The switch for disconnection detection is set by P2.065 [Bit 9], which
is disabled by default. The switch for wiring error detection is set by P2.065 [Bit 8],
which is disabled by default.
Checking method
and corrective action
Check if the motor power cable (U, V, W) and ground wire (GND) are firmly
connected. Follow the instructions in this user manual for correct wiring and proper
grounding.
How to clear the
alarm?
Cycle power on the servo drive.
AL032 Abnormal encoder vibration
Trigger condition
and cause
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.
Checking method
and corrective action
Check if the motor vibration range is within 2.5 G. If the vibration is within the
range but the issue persists, send your servo motor back to the distributor or
contact Delta.
How to clear the
alarm?
DI.ARST or cycle power on the servo drive.
AL034 Encoder internal communication error
Trigger condition
and cause
Condition:
1.
Internal communication error for the absolute encoder.
2.
Internal error for other types of encoder.
Cause: encoder internal communication error.
Checking method
and corrective action
1.
Check if the battery wiring is correct or loose. If it is loose, wire it again and
cycle power on the system.
2.
Check if the battery voltage is within the normal range.
3.
Internal communication error for the absolute encoder occurs. Replace the
motor.
How to clear the
alarm?
Cycle power on the servo drive.
