Characteristic (see parameter value 0) that takes into account the specific
technological features of an application (e.g. textile applications).
The current limitation (Imax controller) only affects the output voltage and not the
•
output frequency.
The slip compensation and resonance damping are disabled.
•
Characteristic (see parameter value 1) that takes into account the specific
technological features of an application (e.g. textile applications).
The current limitation (Imax controller) only affects the output voltage and not the
•
output frequency.
The slip compensation and resonance damping are disabled.
•
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.
Characteristic (see parameter value 1) and Eco mode at constant operating point.
At constant operating point, the efficiency is optimized by varying the voltage.
•
Active slip compensation is necessary here; the scaling must be set so that the
•
slip is fully compensated (p1335 = 100%).
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]).
