Note:
A valid field characteristic (P117=1) must be available when P169 or
P170=1. If one is not, the optimization run for field weakening (P051=27)
must be executed.
P263 determines the input quantity for the motor flux calculation.

P173 Source for "Torque control / Current control" switchover
*
BDS
The binector selected here has the same effect as parameter P170.
0 = binector B0000
(G160)
1 = binector B0001
etc.
P175 Source for variable P gain
*
FDS
The content of the selected connector acts as the P gain for the armature
(G162)
current controller after multiplication with P155.
P176 Source for variable Integration time
*
The content of the selected connector acts as the integration time for the
FDS
armature current controller after multiplication with P156.
(G162)
P177 Source for the command "no immediate pulse disable"
*
BDS
A low signal causes the armature firing pulses to be disabled immediately
without waiting for the I=0 signal or without outputting alpha-W pulses for
(G163)
current reduction. The additional alpha-W pulses (acc. to parameters P179
and P161) are not output either. As long as this command is pending, it is
not possible to fall below operating state o1.6.
This command can be used, for example, if it is not a motor that is supplied
by the SIMOREG DC Master but a field and the current is to be reduced via
an external parallel-connected de-excitation resistance.
P178 Source for the command "fire all thyristors simultaneously"
*
BDS
Setting this command (high signal) causes all six thyristors of the thyristor
bridge I to be fired continuously and simultaneously. Switchover to long
(G163)
pulses is automatic. This command is only active if no line voltage is applied
to the armature power section .

Closed-loop current control and current limitation
Closed-loop torque control with torque limitation (the
torque setpoint is converted to a current setpoint: Current
setpoint = torque setpoint / motor flux)
Current limitation is active additionally
Closed-loop current control with torque limitation (the
specified torque limit is converted to a current limit:
Current limit = torque limit / motor flux)
Current limitation is active additionally
Do not set!
