* Flux demand Pr 5.55 is controlled by Mentor MP. Requested bridge is taken from the sign of
Pr 5.55. Positive for the forward bridge and negative (Mentor MP 2 quadrant drives only) for the
reverse bridge. The bridge change only occurs when the flux is zero.
All parameters except Pr 07 and Pr 78 are set-up by the Mentor MP and therefore
NOTE
cannot be adjusted on the FXMP25 field controller.
