Motor data and controller adjustments of the asynchronous motor
7.5.1 Open loop operation (V/f characteristic)
7.5.1.1 Rated frequency (uF.00), boost (uF.01) and delta boost (uF.04 / uF.05)
The voltage/frequency characteristic (U/f) is adjusted with the rated frequency (uF.00) and the boost (uF.01).
The rated frequency adjusts the frequency at which 100 % modulation depth (~input voltage) are achieved. The
boost adjusts the output voltage to 0 Hz. Depending on uF.10 the modulation limit can be further increased in
this stage up to 200 % (see Fig.7.5.1.1).

The delta-boost is a time-limited boost used to overcome large breakaway torques. The delta-boost acts adding
to the boost; but the sum is limited to 25.5 %.

7.5.1.2 Maximal voltage mode (uF.10)
By changing the maximal voltage mode more torque can be released free above the rated frequency through
overmodulation (110% voltage). Raising the v/f-characteristic has an influence at activated energy saving
func-
tion or at voltage stabilisation.
