Hey everyone,

Quick sanity check. I know signal wires don’t need to be particularly beefy however I'm switching my motors over to JMC servos which have the driver built in, so I wasn't sure if this changes things. I use my setup for video production not CNC hence cables are quite long, 7 metres. I'll be using separate cables for power and signal.

For signal I was planning to use 6 core cable for; stp, dir, gnd, enable, disable, and then cable ground (grounding shield to star point in control box). Will this cable be ok? Not sure if 25 AWG is too thin.

These are the motors:

One other quick question. DC power to these drives is just two cables V+ and V- there's no ground run to the motor, or is that V-? SOrry for the obvious question, it's been ages since I've done this.

Thanks for the help
