4.7
47.52 Iq predicted
This parameter displays the predictive current Iq determined by the current prediction pro-
cedure, if the current prediction procedure is switched on.
47.53 Id predicted
This parameter displays the predictive current Id determined by the current prediction pro-
cedure, if the current prediction procedure is switched on.
47.54 Back EMF estimated
EMF acting in the q-direction. Required for field angle monitoring of PMSM.
Bit Meaning
0 Switches the current prediction for the current controller on/off:
0: Current prediction deactivated
1: Current prediction active
1 Feedforward of the ohmic voltage drop at the stator winding (IxR feedfor-
ward):
0: IxR feedforward deactivated
1: IxR feedforward active
2 Selection of the actual current or set value current for the feedforward of
the ohmic voltage drop:
0: Using the actual current value for IxR feedforward
1: Using the current set value for IxR feedforward
3 Reserved
4 0: Udc-Id controller off
1: Udc-Id controller on
5 0: Short circuit brake off
1: Short circuit brake on
6 Reaction when exceeding the threshold for the reactive current brake.
0: Id target = Id max
1: Increase of Id via Udc link-Id controller
