F06.21=2: automatic adjustment
In the automatic adjustment, the optimal flux weakening current will be selected
automatically, but it may affect the dynamic performance of the system or become unstable.
The speed of flux weakening current adjustment can be changed by setting the
proportional gain (F06.24) and integral time (F06.25). However, fast adjustment of the flux
weakening current adjustment may cause instability. This does not need to be changed
manually under normal circumstances.

This parameter is used to determine the amplitude of the high-frequency current
injected during the initial position identification. The larger this value, the higher the
“squeak” sound will be.
