WARNING
UNEXPECTED MOVEMENT
Autotuning m oves the m otor in order to tune the control loops.
• Only s tart the sys tem if there are no pers ons or obs tructions in the zone of operation.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
During autotuning, the motor makes small movements, noise development and oscillations of the system are normal.
-
Auto-tuning is only performed if no stop command has been activated. If a "freewheel stop" or "fast stop" function has been
assigned to a logic input, this input must be set to 1 (active at 0).
-
Auto-tuning takes priority over any run or prefluxing commands, w hich will be taken into account after the auto-tuning
sequence.
-
If auto-tuning detects a fault, the drive displays
[No action]
(nO) and, depending on the configuration of

-
Auto-tuning may last for 1 to 2 seconds. Do not interrupt the process. Wait for the display to change to
[No action]
(nO).
Note:
Motor thermal state has a big influence on tune result. Make the tune w ith the motor stopped and cold.
To redo a tune of the motor, w ait that it is completely stopped and cold. Set first
[Auto tuning]
(tUn)
to
[Eras e tune]
(CLr),
then redo the motor tuning.
The use of the motor tuning w ithout doing a
[Eras e tune]
(CLr)
first is used to get the thermal state estimation of the motor.
In any case, the motor has to be stopped before performing a tune operation.
Cable length has an influence on the Tune result. If the cabling is modified, it is necessary to redo the tune operation.
[No action]
(nO): Auto-tuning not in progress
[Do tune]
(YES): Auto-tuning is performed immediatly if possible, then the parameter automatically changes
to
[No action]
(nO). If the drive state does not allow the tune operation immediately, the parameter changes to
[No]
(nO) and
the operation must be done again.
[Eras e tune]
(CLr): The motor parameters measured by the auto-tuning function are reseted. The default motor parameters
values are used to control the motor.
