0 0 Closed-loop current control and current limitation
0 1 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
1 0 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
1 1 Do not set!
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.

BDS
Source for the command "no immediate pulse disable"[SW 1.8 and
later]
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
current reduction. The additional alpha-W pulses (acc. to parameter 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.

BDS
Source for the command "fire all thyristors simultaneously"
[SW 1.8 and later]
Setting this command (high signal) causes all six thyristors of the thyristor
bridge I to be fired continuously and simultaneously. Switchover to long
pulses is automatic. This command is only active if no line voltage is
applied to the armature power section .

Positive torque limit 2
If "Torque limit switchover" is selected (state of binector selected in P694
=1) and the speed is higher than the threshold speed set in parameter
P184, then torque limit 2 is activated in place of torque limit 1.
