Speed controller adaptation
The speed controller can be adapted, depending on the speed or velo-
city, using the speed/velocity controller adaptation.
For example, in order to better overcome stiction at lower speeds, a
higher proportional gain can be set than for higher speeds.
Adaptation is enabled/disabled with P1413.
The following is valid with the adaptation enabled (P1413 = 1):
Proportional gain (K
p
):
The settings in P1407 and P1408 are effective as a function of the
lower (P1411) and upper thresholds (P1412).
The values are linearly interpolated in the adaptation range.
Integral action time (T
N
):
The settings in P1409 and P1410 are effective as a function of the
lower (P1411) and upper thresholds (P1412).
With adaptation disabled (P1413 = 0) the following is valid:
The proportional gain (K
p
, P1407) and the integral action time (T
N
,
P1409) are effective over the complete range.
