Normalization of the closed-loop controller signals

Armature circuit.
Actual speed value: 100% corresponds to the pulse encoder evaluation of the set maximum
speed in p2000; for the analog tachometer, 100% corresponds to the tachometer voltage in
accordance with P50741. The following applies with EMF as the actual value: 100% speed
corresponds to an EMF in accordance with
p50078[0] * p50115. The same applies for speed setpoint normalization.
Speed controller output r52160, Parameter Manual Section 2 Sheet 6815 dependent on
p50170, p50170 = 0: 100% corresponds to the actual rated DC device current for armature
(r50072[1]); p50170 = 1: 100% corresponds to the torque of actual rated DC device current
(r50072[1]) and 100% flux PHI (is p50102 for rated field current).
From r52134, Sheet 6835 and to the right of it, 100% corresponds to r50072[1].
Actual current value for armature r52117, Sheet 6855: 100% corresponds to r50072[1]
Delay angle r52110, r52121, r52102, Sheet 6855; r520101, r52100, Sheet 6860:
100% corresponds to 0 degrees, 0% corresponds to 90 degrees, -100% corresponds to 180
degrees.
Field circuit:
Actual EMF value r52286, r52285, Sheet 6900: 100% corresponds to r50078[0] * 1.35
Output EMF control loop, r52280, r52293, field current setpoint r52277 to r52268:
100% corresponds to the actual rated DC device current field (r50073[1]).
Output field current control loop (firing angle, field), Sheet 6910 :
r52260, r52271, r52252:
100% = 0 degrees, 0% = 90 degrees, -100% = 180 degree delay angle.

Fixed values:

See Sheet 3100 in Section 2 of the List Manual
Fixed values in %, fixed values decimal, fixed control bits, constant fixed values and control
bits.

Free function blocks:

With SINAMICS DCM, an abundance of function blocks (52 in total) can be utilized at no
additional cost. The blocks can be selected and have parameters assigned to them by
means of BOP20, AOP30 or STARTER. These can be selected at various DOs (even in the
case of several).
Select via BOP20, e.g. for DO2:
These parameters are in DO1,
