List of Self-tuning Error Messages
Generic messages
Description Note
“Drive disabled”: Provide enable input by setting terminal 12 high.
“Not ready”: “Take values part 1”, “Take values part 2a”, “Take values part 2b”or “Take values part 3”
can not be executed because the measurement has not been completed correctly. Repeat
self-tune procedure.
“Time out”: Measurement has not been completed in the proper time.
“Start part…?”: Press [ENTER] to confirm start of measurement.
“Tuning aborted”: Measurement aborted by user ([SHIFT] / [Escape] button has been pressed).
“Set Main cmd=Dig”: Go to CONFIGURATION menu and set Main commands = digital.
“Set Ctrl=Local”: Go to CONFIGURATION menu and set Control mode = Local.
“Reg mode NOK”: Self tune part 3 can only be executed with Regulation mode = Field oriented or Regulation
mode = Sensorless vect. Go to BASIC MENU and set Regulation mode properly.
“Inertia range”: Self-tuning part 3 procedure has found an inertia motor value too low, for this reason it
cannot calculate the speed regulator gains. Try to repeat the self-tune procedure to eliminate
accidental measurement errors.
If this error persist , do not use the “Take val part 3”command. The speed regulator will
probably be stable with the factory gains. It is possible to optimize the speed regulator by
manual tuning .
Measurement error messages
These messages may occour when extreme parameter values have been identified. It may be useful to retry the self
tune command when any of the following messages occur. If the messages persist, alternative manual tuning procedures
should be used.
Description Note
“No break point” Self-tune Part 1 failed. Check the connections between the drive and the motor and repeat
self-tune Part 1.
“Overspeed” Self-tune Part 3 detected a much higher speed than expected. Repeat Self-tune 1 or the
manual tuning that was performed.
“Drive stalled”: Increase value of parameter Test T curr lim and repeat Self tune 3
“Load applied”: Nominal zero load torque at standstill was detected. Self tune 3 is impossible for this type
of load.
“T curr too high”: Reduce value of parameter Test T curr lim for Self tune 3
“Friction null”: Value of friction is zero or lower than the accuracy limit of the control system.
