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.
Figure 7-13
A dynamic response reduction in the field-weakening range can be activated in encoderless
operation (p1400.0). This is activated when the speed controller is optimized in order to
achieve a greater dynamic response in the base speed range.
Example of speed-dependent adaptation
Note
This type of adaptation is only active in "operation with encoder" mode.
