LIST OF SELF TUNE ERROR MESSAGES
- Generic messages
Description Note
“Drive disabled”: Provide enable input by setting terminal 12 high.
“Not ready”: “Take values part 1” or “Take values part 2a” or “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] buttons 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 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 self tune procedure
to overcome possible accidental measure error.
If this error persist (inertia is really lower than the measurable minimum value),
avoid to give “Take val part 3”command. The speed regulator will be also stable
with the factory gains value. It is possible to optimize the feedback speed by using
the regulator manual tuning .
- Measurement error messages
These messages may occour when extreme parameter values have to be identified. It can be useful to retry
the self tune command when any of the following messages occours. If messages persist, alternative manual
tuning procedures should be adopted.
Description Note
“No break point” Self tune part1 failed. Check integrity of connections between inverter and motor
prior to attempt repeating part 1.
“Over speed” Self tune part3 detected a a much higher speed than expected. Possible causes are:
load causing a speed drift or bad tuning of inner loops when using Sensorless vector
mode. Try repeating Self tune 1 or the corresponding manual tune operations.
“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.
