Actual value feedback
Armature voltage feedback
In speed control with armature voltage feedback, the actual speed signal is
generated ba an internal armature voltage detection. Select C005 = -10- or -40-.
The value under C232 (adjustable 0 ... 30% of C090) compensated for the speed
error generated by the IôR component of the armature voltage.
Select the "I¼R-compensation" such that the smallest speed occurs between
motor loading and unloading.
Stop!
( Field-weakening operation is not possible with this configuration.
( The monitoring "Armature circuit interrupted" (ACI) must be solved externally
for this configuration, because an interruption cannot be reliably detected.
