Also, common mode chokes on the DC INPUT to the 7i29
might be of help.
The 7i29 doesn't have any big reservoir capacitors on
board. I was always taught that H bridges need a nice low
impedance supply. Adding inductance doesn't strike me as
being a good idea. I could of course be wrong.
A common-mode inductor should not add much inductance to the
DC circuit, only prevent it from radiating. You run both
wires through the eye of the core.
