This mode makes fieldbus control operate as is explained in the
fieldbus board manual.

Simple control word that is used in modes where the control word
from fieldbus is used as such. For some fieldbus boards this
requires bypass operation.
3 / Vacon AFE 1
This mode uses a ProfiDrive type state machine in the application
level. It is possible to use this mode on fieldbus boards that do not
have a state machine or have a possibility to bypass the state
machine function on the option board.

FB DC Reference
Fieldbus DC reference is available when the Grid Converter is in fieldbus control.The format is the
same as in panel references. (11000 = 110 %). If reference is not used from fieldbus, set the
“FBSpeedReference” to zero. When FB reference is zero, the drive will use DC Voltage Reference
