6.3.5 External generation of the feed forward control signals
In this operation mode the master cyclically species position reference values and
feed forward control signals for speed and acceleration. The drive undertakes ne
interpolation for the
position reference values and the feed forward control signals. The scaled feed forward
control signals are descaled using the parameter P1507 speed or P1508 acceleration.
The position reference value and feed forward control signals are further processed
as for the operation mode described in 6.4.1.
