Generic messages

"Set Ctrl=Local":
"Reg mode NOK":
"Inertia range":
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
"No break point"
"Overspeed"
"Drive stalled":
"Load applied":
"T curr too high":
"Friction null":
24
Note
Provide enable input by setting terminal 12 high.
"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.
Measurement has not been completed in the proper time.
Press [ENTER] to confirm start of measurement.
Measurement aborted by user ([SHIFT] / [Escape] button has been pressed).
Go to CONFIGURATION menu and set Main commands = digital.
Go to CONFIGURATION menu and set Control mode = Local.
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.
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 .
Note
Self-tune Part 1 failed. Check the connections between the drive and the motor and repeat
self-tune Part 1.
Self-tune Part 3 detected a much higher speed than expected. Repeat Self-tune 1 or the
manual tuning that was performed.
Increase value of parameter Test T curr lim and repeat Self tune 3
Nominal zero load torque at standstill was detected. Self tune 3 is impossible for this type
of load.
Reduce value of parameter Test T curr lim for Self tune 3
Value of friction is zero or lower than the accuracy limit of the control system.
