Wiring an 8 wire Nema to 4 core CY cable to an AM882

[JAZZCNC]

Let's explore this a bit though; those 4nm Nema23s from CNC4YOU just have "current" listed in the datasheet as 4A. Now is that likely to be a peak or RMS current suggestion?

My EM806 drivers, essentially the same as Desertboy's, have a current table with Peak and RMS, what settings would you use for these motors?

Most data sheets nearly always quote peak ratings, so if doesn't state RMS always go with peak.

I'm kinda surprised we're talking about this machine being able to reach 20m/min, I'm stalling at half that!

Couple of reason why he'll be getting that speed. If he really is because 2000rpm is high for a stepper.? (Have you checked the machines moving correct distance.? If steps Per is wrong you'll get false reading)

#1 He's only running at 400 Ms so will have more torque but the motors will be running very rough.
# 2 He's running well above 70vdc and close to 80V
