Trigger condition
and causes
Revision December, 2017
Disable the filter if not required, such as low-pass filter (P1.006 —
P1.008), moving filter (P1.068), low-frequency vibration suppression
(P1.025 — P1.028), vibration elimination (elasticity compensation)
(P1.089 — P1.094), or Notch filter (5 sets).
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.
1. Remove or reposition the interference source.
2. Set P2.112 [Bit 1] to 0 to disable AL089.
3. If the issue persists, please send the servo drive back to the distributor
or contact Delta.
Condition: no command is issued when the servo drive starts the
auto-tuning procedure.
Causes:
1. When the command source is the controller, neither the controller nor
the position register issue the command.
2. When command source is the servo drive, position 1 and 2 specify the
same position.
3. The signal cable is not connected or incorrectly connected so that the
servo drive cannot receive the command.
1. Make sure a command is being issued.
2. Make sure the wiring between the controller and servo drive is correct.
DI.ARST
Condition: inertia estimation error occurs when the servo drive starts the
auto-tuning procedure.
Causes:
1. Acceleration/deceleration time is too long.
2. Rotation speed is too slow.
3. Inertia of the machine is too large.
