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 or reposition the interference source.
1.
Set P2.112 [Bit 1] to 0 to disable AL089.
2.
If the issue persists, send your servo drive back to the distributor or
3.
contact Delta.
Condition: no command is issued when 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 2 specify the
2.
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.
Make sure the wiring between the controller and servo drive is correct.

Condition: the pause time is too short when the controller is the command source
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 pause time is
too short.
Cause: pause time in the cycle is too short.
For a reciprocating motion between two points, pausing is required on the
1.
return, which has to be longer than 1 second.
For rotation in a single direction, pause time is required when the motor
2.
rotates a certain number of cycles (> 2 cycles).
