7.6.3 n controller adaptation
Purpose
The adaptation of the speed controller is to improve the control behaviour. It is
recommended for
( low speed set-values (start)
( set-value jumps from n
x
-> 0 (stop) without return and drives with high
inertias.

FIG 7-53 Characteristic for internally derived n controller adaptation
The n controller adaptation is enable under C324 = -1-. The input of the n
controller adaptation must not be assigned with an analog signal (see C145 /
C146).
