Standard with variable voltage boost
Characteristic that compensates for voltage
losses in the stator resistance for static /
dynamic loads (flux current control FCC).
This is particularly useful for small motors,
since they have a relatively high stator re-
sistance.
Characteristic that takes into account the
motor torque curve (e.g. fan/pump).
Quadratic characteristic (f² characteristic)
•
Energy saving because the low voltage
•
also results in small currents and losses.
Characteristic that takes into account the
motor/machine torque characteristic.
Characteristic (see parameter value 0) 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%).
