AL030 Motor crash error
Trigger condition
and cause
Condition: when the motor hits the device, the torque reaches the value of P1.057
and lasts for the time set by P1.058.
Cause:
1.
Check if the function of motor crash protection (P1.057) is enabled.
If so, set P1.057 to 0.
2.
Check if the value of P1.057 is set too low and the time set by P1.058 is too
short. Set P1.057 according to the actual torque. Incorrect values might
inadvertently trigger the signal or lose the protection function.
Checking method
and corrective
action
Cycle the power to the servo drive to operate the motor. Then, check if the alarm
occurs again. If the issue persists, replace the encoder.

AL031 Motor power cable disconnection
Trigger condition
and cause
Condition: incorrect wiring or disconnection of the motor power cable U, V, W, and
GND.
Cause:
Incorrect wiring or disconnection of the motor power cable U, V, W. The switch for
cut-off detection is set by P2.065 Bit 9, which default is set to disable.
Checking method
and corrective
action
Check if the motor power cable (U, V, W, GND) is firmly connected. Connect wiring
and ground properly by following the instructions in this user manual.
How to clear the
alarm?
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 the other type 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.
