47.50 Dead time compensation factor
Dead time compensation factor: 100% means that exactly the determined voltages have
been pilot controlled. The standard value is 0%, i.e., no compensation.
Compensation can be carried out using measured values or with default values (if dead
time measurement wasn't executed). See dead time correction table
Z123.15–.
47.51 Current controller mode
Switches the current prediction for the current controller on/off.
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.
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
15 ... 7 Reserved
