0 = None, "No restriction of direction of rotation"
1 = Dir key locked, rotation direction change key
2 = Clockwise only*, only clockwise direction is possible. The selection of the "incorrect"
rotation direction leads to the output of the minimum frequency P104 with the field of
rotation R.
3 = Anticlockwise only*, only counter-clockwise direction is possible. The selection of the
"incorrect" rotation direction leads to the output of the minimum frequency P104 with the
field of rotation L.
4 = Enable direction only, rotation direction is only possible according to the enable signal,
otherwise 0Hz.
5 = Clockwise only monitored, "Only clockwise monitored*, only clockwise rotation is
possible. The selection of the "incorrect" rotation direction leads to the FI switching off
