Characteristic that takes into account
motor/machine torque curve (e.g.
synchronous motor).
Characteristic, see parameter 0 and Eco mode at a constant operating point.
In the Eco mode, the efficiency at a constant operating point is optimized.
•
This optimization is only effective in steady-state operation and when the
ramp-function generator is not bypassed.
You must activate slip compensation and set the scaling of the slip
•
compensation (p1335) so that the slip is completely compensated (generally,
100%).
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 function is required for small
motors, as, in comparison to large motors, they have a relatively high stator
resistance.
Characteristic, see parameter 1 and Eco mode at a constant operating point.

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]).
