Description
Enabling/disabling
adaptation
6-338
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.
S
The following is valid with the adaptation enabled (P1413 = 1):
Proportional gain (K
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
The settings in P1409 and P1410 are effective as a function of the
lower (P1411) and upper thresholds (P1412).
S
With adaptation disabled (P1413 = 0) the following is valid:
The proportional gain (K
P1409) are effective over the complete range.
