Speed controller adaptation

Description
Two adaptation methods are available, namely free Kp_n adaptation and speed-
dependent Kp_n/Tn_n adaptation.
Free Kp_n adaptation is also active in "operation without encoder" mode and is
used in "operation with encoder" mode as an additional factor for speed-dependent
Kp_n adaptation.
Speed-dependent Kp_n/Tn_n adaptation is only active in "operation with encoder"
mode and also affects the Tn_n value.
