Current controller adaptation
Current controller adaptation can be used to adapt the P gain of the current controller and
the dynamic precontrol of the I
The current controller adaptation is directly activated with setting p1402.2 = 1 or deactivated
with p1402.2 = 0.
Using p1959.5, it is automatically activated (p1959.5 = 1) or deactivated (p1959.5 = 0).

When swapping the I
