Yes I've had it connected to a pulse generator earlier on, but of course that's a source output rather than a sink, it seemed to work ok I think, I will upload a video later on with a pulse genny on the DM856.

The motor just sits on a desk, I can probably clamp it down for further tests.

As I said before the PIC is powered from a plug-in 9VDC power supply, which is connected to the same 230VAC source as the 68VDC PSU which powers the motor / driver.

On the 7805 I have 9VDC on the input and 5.01VDC on the output.
