No motion from project using KL4030 driver

[Delanoman]

Stepper is a FL57STH56-3006B, 6 lead stepper motor, 3.0 amps, 1.8, 2.3v
Driver is a KL4030
5vdc Power source (driver and breakout board)
38v dc Power source ( steppers)

The stepper wires are:

Black}Green
white-Common

Red}Blue
Yellow-Common

Also i did a test to find that:

Blue is coil 1
Black is coil 2
Red in coil 3
Teal is coil 4

I connected the motor to my driver with:

Yellow&White- +38v
Black- A+
Teal- A-
Red- B+
Blue- B-

Does anyone know is this is correct at all?

I have been unsuccessful at generating any movement from my steppers. All that happens with i plug in my setup is the motor seizes up (which i think is fine). I have been trying to get movement using a simple beta program called "Stepster". Is there any other free software that might resolve my problems? Any help is appreciated- thanks.

Well, as I see it you have 8 coils with 2 commons.

The Teal is also the green?

In Bipolar (parallel) the common of the common (white) should go to A- and Black/Green should go to A+.

Don't you have a datasheet for the steppers?

38 VDC should only be applied to the V++ of the driver and not the driver coils.

I use Mach3. I hope that helps.

The other common (yellow) should go to B- and Red/Blue should go to B+.

Well that certainly is a different way from which i wired it up. I do have a data sheet, i found it off the internet at http://www.akcesoria.cnc.info.pl/pli...owe.pdf?t=2239 page 25. I don't find it extremely helpful tho because it doesn't make it clear as day for me. Thanks

Also where i wrote Black}Green, I didn't mean that the wire is colored black and green, I was trying to show a description of the wiring diagram i have off of the net.

such as:

Black
Yellow MOTOR
Green
Red White Blue

[Delanoman]

resetting the wire leads didn't fix the problem, I've still only got holding torque. Is there a trial of Mach3 or something else that will allow me to test my setup without a full purchase?

[ViperTX]

Yes, you can download Mach3, I believe from ArtSoft.com or net....forget which do a Google.

Do you have the outputs on your BOB enabled?

[ViperTX]

Okay, that's better.

Yellow goes to A- and Blk & Green go to A+.

White goes to B- and Red & Blue go to B+.

If that doesn't work just switch them out.....all the A's go to B's and the B's go to A's.

Are the BOB's outputs enabled?

[Delanoman]

I am not sure if the BOB outputs are enabled. On the breakout board i did put wires going from the Xlimit and the E stop into the Common that a circuit would be made there, but that had no effect on my dilemma.

[ViperTX]

I don't know which BOB you have, but generally +5 VDC goes to the enable, then to E-Stop (Normally Closed) and the E-Stop's input pin on the BOB.

Generally all the limit switches are wired serially, and I believe most BOBs use a separate input pin for the limit switches. One side of the limit switches has +5VDC and the other side goes to the input pin.

Which BOB do you have?

[Delanoman]

I am fairly certain i am using the KL-DB25 Breakout
Board From keling

[Delanoman]

I got it working, The problem had to do with the Mach 3 setup. After about 20 different searches and countless hours through these forums i found an article with a link to a document by Keling showing how to properly configure Mach3 for my application.

I get movement now wired at

A+ BLACK
A- GREEN
B+ RED
B- BLUE

the two common wires are not in use. My NEXT question is what will the difference be if i use them (torque,Speed), and how should they be put in?
