Description
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
Value to which the field current is reduced when "Automatic field current
FDS
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
Delay after which the field current is reduced to the value set in parameter
FDS
P257 with automatic or signal-driven "Field current reduction" function when
the drive is stopped after operating state o7.0 or higher is reached.
(G166)
P260
Filter time for setpoint for field current precontrol
Filtering of the field current setpoint at the input of the precontrol for the field
FDS
current controller.
The purpose of this filter is to decouple the field current precontrol from the
(G166)
field current controller.
P261
Filter time for setpoint for field current controller
Filtering of the field current setpoint at the input of the field current
FDS
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
used in connection with a fully compensated DC machine
(G166)
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.
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
*
BDS
Selection of the binector to supply the field monitoring signal when an
external field device is used.
(G167)
(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.
