Å 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).

z-axis downward movement: 28 ms +
2 ms (see fig 7.4 - 8),
z-axis upward movement: 23 ms +
1 ms (see fig 7.4 - 9) is reached.
