Trigger condition
and cause
Condition: current detection interference.
Cause: current detection in the servo drive is affected by an external interference
source.
Check the environment around the servo drive to see if there is any interference
source.
Remove the interference source or move the servo drive away from the
1.
interference source.
Set P2.112 [Bit 1] to 0 to disable AL089.

Delta.
Condition: no command is issued within 15 seconds after the servo drive starts the
auto-tuning procedure.
Cause:
When the command source is the controller, neither the controller nor the
1.
position register issued the command.
When the command source is the servo drive, Position 1 and Position 2
2.
specify the same position.
The signal cable is not connected or incorrectly connected so that the servo
3.
drive cannot receive the command.
Make sure a command is being issued.
1.
Set Postion 1 and Position 2 again.
2.
Make sure the wiring between the controller and servo drive is correct.
3.
DI.ARST
Condition: the dwell time is too short when the command source is the controller in
the auto-tuning procedure. The auto-tuning algorithm requires a certain amount of
time to perform the calculation. The tuning result is affected if the dwell time is too
short.
Cause: dwell time in the cycle is too short.
