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

[Desertboy]

I was aware that going slightly over would just lead to more cooling requirements, but didn't realize they were quite so lenient.

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?

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

They should have an autotune function like the AM882's have a look in the manual, I used it with my first motors and it really did seem to work.

It's something that I've not done yet but is on my list. Does it suggest a current setting for you?

No, it doesn't, you still have to set the current using the Dip switches or can connect to drives and use software to set them more accurately in 0.1a increments.

The autotune can make a big difference and it's certainly something you should do. Do your motors Hiss or squeal.? . . . If so they will stop after Autotune
