Need lp wiring Univelop 5axis controller

[elrieger]

Jerry,
five nema 23 motors (kn56km28093) 2A each
I would really appreciate some pics
not sure how to wire the power correctly
the 7V and 12V connections are whats unclear to me
an example would really help me understand
thanks

Rick,

I'm not able to find anything about the motors searching those numbers on Google. Do you have a link to the motor specs?

The 7V inputs are for powering the electronics on the boards themselves, the 12V inputs are for the power that will be sent to the motors.

What power supply or supplies are you planning to use?

Jerry

this is the info i got!
5X (118 oz-in) They are six wire 2 phase stepping motors. Each phase is 4 ohms or 2 ohms center tap to end.
KH56KM2-OEM (last 3 digits are custom to the OEM)

i'm not sure what power supply or supplies i am planning to use.

that's what i'm trying to figure out, i'm ready to order as soon as i figure it out!

what do you recommend?

thanks

Ok,
So does my wiring layout look correct?
And are my power supply options ok?
let me know
thanks

Rick,

Your wiring puts my spaghetti to shame!

I have a couple of reservations about your setup: 1. Do you have the two short wires of each motor hooked together? I do not believe that they should be. The wire colors do not match the PDF info on the motors that you posted the link to, so I do not know which wire is which, but on a 6-wire stepper motor I don't think you tie wires together to run it in bipolar mode. 2. I am worried that the stepper motors are made to draw more current than the drivers are desgned to handle.

Other than that, I think your wiring is correct.

I would still suggest that you try 1 motor to begin with, so if there is a problem, you only have to repair 1 driver.

HTH

Rick,

I was just thinking, since your motors are unipolar that you are driving as bipolar, as long as you connect across the full winding on each side, you should be OK as far as current goes. Referring to the second page of the PDF that you linked to: connect one side of the driver board (A): A+ to the Black and A- to the Brown('Blown') wires and the other side of the driver (B): B+ to the Yellow and B- to the Orange('Orenge') wires of the motor. You will need to determine which wires correspond to which on your motor.

I would still test with a single motor-driver combination to make sure it will work before firing them all up.

HTH

Thanks Jerry,
for catching the mistake with my motor wiring, i shoudnt have connected those wires together.
So the power supply choices are ok?
I should go ahead and order them?
thanks for the help

[elrieger]

do you think i should add resistors or fuses?
if so where?
thanks
rick

[apache405]

fuse one lead from each motor with a slow blow fuse, to keep the drivers from blowing up.

[elrieger]

So wich wires do i connect the fuses to?

A

Let me know

what do you think about those cards ?
can you send me the documentationof those cards ?
thanks
