Trigger condition
and cause
Checking method
and corrective action
Check if the absolute origin position is established (refer to Section 10.3.1 for
1.
more information).
Avoid replacing the battery when the servo drive is powered off. It is suggested
2.
that you replace the battery when the servo drive is powered on, so the absolute
encoder has continuous power supply.
Re-establish the absolute origin position.
3.
Replace the encoder cable. Use the X-ray to check if the internal wiring is
4.
damaged.
Check if the wiring is loose. If the wiring is fine, replace the battery box for
5.
cross-testing.
Replace the servo motor.
6.
Ensure J1 is connected to the battery and J2 is connected to the servo drive.
7.
This alarm is automatically cleared after you establish the absolute origin position.
Condition: when the absolute motor is powered by the battery, the number of motor
rotations exceeds half the number of revolutions of the encoder resolution.
Cause: the error between the servo drive internal position and the encoder position
is too large.
The mechanical parts are not properly fastened when the machine is being
transported causing rotation of the motor.
Re-establish the absolute origin position.
The servo drive cannot identify the encoder type.
N/A
Replace the motor immediately.
Condition: the establishment of the absolute position has timed out.
Cause: the process for establishing the absolute position of the servo drive is in
error.
If the issue persists after you cycle power on the servo drive and re-establish the
absolute origin position, contact your local distributor or technician.
