– If the dynamics of the star are correct, each signal will appear as illustrated above.
– Nominal - positioning time: 685 dgts: 28 ms +
2 ms.
– Adjust the speed and the P-gain potentiomete alternately, so that you get the profil in
Fig. 9.6 - 5 .

➠ Increase the P-gain until an acceptable positioning of the axis becomes possible. Acceptable
means that a clear rounding at the rising edge of the nominal value has formed during transi-
tion to position control.
NOTE
Any oscillation of the current curve must be avoided.
Vnominal must be visibly rounded in the marked area.
(See marked circle in the illustration above).
