Functions with Open-Loop-operation
16.8.3.1
U/f-characteristic curve
With entering the motor data in the menu
motor name plate
the parameters "U0", "U1", "f1" and "f2"
will be pre-assigned. By these parameters the U/f-characteristic curve will be de
fi
ned. The U/f-
characteristic curve sets the motor voltage depending on the frequency of the rotating
fi
eld in the
stator.

16.8.3.2
Current-control
For improving the startin, the stopping as well as the travelling with a slow speed, the motor will be
energised with a minimum current (Parameter
Controller/I_IxR
). With the parameters FADE1 and
FADE2 the current can be set depending on the frequency (f) of the rotating
fi
eld in the stator.
f < FADE1:
If the frequency of the rotating
fi
eld in the stator is less than FADE1 the motor will be energised with
100% of I_IxR.
f > FADE2:
If the frequency of the rotating
fi
eld in the stator is greater than FADE2 the current I_IxR is 0
