<1> The linearization calculates with p0311[MDS] and MDS = p0186[0].
<2> p3519[0] ... p3519[3] are standardized via r2004.
<3> When r3405.1 = 0 (Vdc controller inhibited): The voltage setpoint is routed with the DC link voltage.
When r3405.1 = 0 à 1 (Vdc controller is enabled): The setpoint is adjusted to the specified setpoint value in 100 sampling steps.
