How to clear the
alarm?
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:
Check if the function of motor crash protection (P1.057) is enabled.
1.
If so, set P1.057 to 0.
Check if the value of P1.057 is set too low and the time set by P1.058 is too
2.
short. Set P1.057 according to the actual torque. Incorrect values might
inadvertently trigger the signal or lose the protection function.
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.
DI.ARST
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.
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.
Cycle power on the servo drive.
Condition:
Internal communication error for the absolute encoder.
1.
Internal error for the other type of encoder.
2.
Cause: encoder internal communication error.
Check if the battery wiring is correct or loose. If it is loose, wire it again and
1.
cycle power on the system.
Check if the battery voltage is within the normal range.
2.
Internal communication error for the absolute encoder occurs.
3.
Replace the motor.
Cycle power on the servo drive.
