Cronin,
the 7354 doesn't offer a way to manipulate the feedback signals before
they are used in the control loop. The DSP of the board talks directly
to the analog inputs so any manipulation would have to be done in the
firmware which can't be changed by the end user. If necessary filtering
should be done in external signal conditioning hardware.
On the other hand NI offers products to build your own motion
controller based on LabVIEW Realtime and (optionally) LabVIEW FPGA
hardware. The
NI
SoftMotion Development Module for LabVIEW gives you the the flexibility
to choose from a variety of hardware platforms the best fit for your
application. As the trajectory generation and the control loop are
running in LabVIEW you can manipulate literally every single piece of
the motion controller including the feedback signals and the control
algorithm.
Please have a look at
