Hi Rick

Did you already check the Argon wiki pages? Here we have examples and the schematics for the inputs:

I’m assuming you are using step/dir setpoint signal, and for this I would skip the VSDEPI and wire the smoothstepper directly to Argon (and VSD).

Here’s an example to single-ended step/dir wiring:

Kidn regards,


Thank you Esa,
I will skip the VSDEPI,I just want to run the servo in real conditions before I buy more drives.
