Flux controller (ASM)
The flux controller for the asynchronous motor is a PI controller.
The set flow (ImrRef) is made up of a characteristic value (flux control) and the out-
put of the maximum voltage controller.
Different options for the flux controller can be selected with fc16 ASM flux mode.

cubic => Flux controller limit rises cubically (x³) from 0 at speed
0 to fc20 at speed dr25 (breakdown speed)
start off => the flux controller is not active at flux build-up
start on => the flux controller limit fc20 applies at flux build-up
