Field current controller reset time
This parameter is set automatically during the optimization run for precontrol
and current controller (armature and field) (P051=25).

Standstill field
Value to which the field current is reduced when "Automatic field current
reduction" function is parameterized (by means of P082=2) or with signal-
driven selection of "Standstill excitation" function (selected in P692).

the drive is stopped after operating state o7.0 or higher is reached.

Filter time for setpoint for field current precontrol [SW 1.9 and later]
Filtering of the field current setpoint at the input of the precontrol for the field
current controller.
The purpose of this filter is to decouple the field current precontrol from the
field current controller.

Input quantity for motor flux calculation
0 The input quantity for the motor flux calculation is the field
current controller actual value according to P612 (K0265), to be
used in connection with a fully compensated DC machine
1 The input quantity for the motor flux calculation is the precontrol
output for the EMF controller (K0293)
(exception: Field current controller setpoint (K0268) with active
standstill field or with disabled field pulses), to be used in
connection with an non-compensated DC machine. The EMF
controller must
be active when this setting is selected (EMF
controller compensates the armature reaction).
2 The input quantity for the motor flux calculation is the field
current controller setpoint (K0268). Advantage: Quantities
derived from the setpoint are generally "steadier" than those
derived from actual values.

Source for selection of external field current monitoring signal
[SW 1.9 and later]
Selection of the binector to supply the field monitoring signal when an
external field device is used.
(status "1" = field current is o.k., If > If-min)
The converter waits for this signal in state o5.0 as part of the power ON
routine. If the signal disappears during operation, the drive is shut down with
fault message F005, fault value 4.
0 = binector B0000
1 = binector B0001
