EMI/RFI Concerns and Stepper Motor Wiring

#1

Hi,

a long time back I had read documentation of a CNC controller (Can’t remember the brand or type) which had a bunch of options listed to correctly wire up Stepper Motors with shielded cable and twisted pair wires. I do remember it was very important to have the right pairs twisted and the shield connected to the right place for it to be effective and not make interference worse. Has anybody come across a good documentation with explanation ? I would very much appreciate a link if someone has info.

Thanks
