[V/F 5pts] (UF5): 5-segment V/F profile: As [Standard] (Std) profile but also supports the avoidance of resonance
(saturation).
Note: U0 is the result of an internal calculation based on motor parameters and multiplied by UFr (%). U0 can be adjusted by
modifying UFr value.
[Sync. mot.] (SYn): For synchronous permanent magnet motors with sinusoidal electromotive force (EMF) only. This selection
makes the asynchronous motor parameters inaccessible, and the synchronous motor parameters accessible.
[V/F Quad.] (UFq): Variable torque. For pump and fan applications.
[Energy Sav.] (nLd): Energy saving. For applications that do not require high dynamics.
