Select Special motor mode [8], if a special U/f set-
ting is needed that is to be adapted to the present
motor. The break points are set in parameters 423-
428 Voltage/frequency.
NB!:
Please note that if a value set in the name-
plate parameters 102-106 is changed, there
will be an automatic change of parameter 108 Stator
resistance and 109 Stator reactance.
