Characteristic that takes into account the technological particularity of an
application (e.g. textile applications):
a) whereby the current limitation (Imax controller) only affects the output voltage
and not the output frequency, or
b) by disabling slip compensation

Voltage losses in the stator resistance for static / dynamic loads are also
compensated (flux current control FCC). This is particularly useful for small
motors, since they have a relatively high stator resistance.
The user can define the output voltage of the Motor Module independently of the
frequency using BICO parameter p1330 via the interfaces (e.g. analog input AI0
of Terminal Board 30 –> p1330 = r4055[0]).
