The parameters can only be modified with the speed controller stopped and locked, except for Frt, SFr,
nrd and SdS, which can be adjusted with the controller running.
Drive performance can be optimized by :
- entering the values given on the rating plate
- performing an auto-tune operation (on a standard asynchronous motor)

resistance.
Only active for V/F ratios : n and nLd (Uft parameter)
- no (factory parameters of standard IEC motors)
- donE (auto-tuning already done) : use the parameters of the auto-tune
which has already been done
- YES : starts auto-tuning
When auto-tuning is complete, rdY is displayed. On returning to tUn, donE
is displayed. If the fault tnF appears, check that the motor is connected
correctly. If the connection is correct, the motor is not suitable : use the L or
the P ratio (Uft parameter).
Caution : Auto-tuning will only be performed if no command has been
activated. If a "freewheel" or "fast stop" function is assigned to a logic input,
this input must be set to 1 (active at 0).
