Figure 4-5 Kp_n-/Tn_n adaptation
Dynamic response reduction in the field-weakening range can be activated (p1400.0) with
sensorless operation. This is activated when the speed controller is optimized in order to
achieve a greater dynamic response in the basic speed range.
Example of speed-dependent adaptation
Note
This type of adaptation is only active in "operation with encoder" mode.
