Characteristic (see parameter value 1) that takes into account the technological
particularity of an application (e.g. textile applications):
Whereby current limitation (Imax controller) only affects the output voltage and not
•
the output frequency.
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 Power Module independently of the
frequency using BICO parameter p1330 via the interfaces (e.g., analog input AI0 of
the TM31 –> p1330 = r4055[0]).
