P256	Field current controller reset time
FDS	This parameter is set automatically during the optimization run for precontrol
(G166)	and current controller (armature and field) (P051=25).
P257	Standstill field
FDS	Value to which the field current is reduced when "Automatic field current
	reduction" function is parameterized (by means of P082=2) or with signal-
(G166)	driven selection of "Standstill excitation" function (selected in P692).
P258	Delay time with automatic field current reduction
FDS	Delay after which the field current is reduced to the value set in parameter
	P257 with automatic or signal-driven "Field current reduction" function when
(G166)	the drive is stopped after operating state o7.0 or higher is reached.
P260	Filter time for setpoint for field current precontrol		[SW 1.9 and later]
FDS	Filtering of the field current setpoint at the input of the precontrol for the field
	current controller.
(G166)	The purpose of this filter is to decouple the field current precontrol from the
	field current controller.
P261	Filter time for setpoint for field current controller		[SW 1.9 and later]
FDS	Filtering of the field current setpoint at the input of the field current
	controller.
(G166)	The purpose of this filter is to decouple the field current precontrol from the
	field current controller.
P263	Input quantity for motor flux calculation
*	0	The input quantity for the motor flux calculation is the field
FDS
		current controller actual value according to P612 (K0265), to be
(G166)		used in connection with a fully compensated DC machine

1The 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).

2The 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.

P264	Set field current controller P component to zero
*	0	Set controller P component to zero (i.e. to obtain pure I
FDS
		controller)
(G166)
	1	Controller P component is active

P265	Source for selection of external field current monitoring signal
*	[SW 1.9 and later]
BDS	Selection of the binector to supply the field monitoring signal when an
(G167)	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
	etc.
