Gecko 203V Bridgeport stepper wiring

[kosmo]

Looking for BP stepper motor parallel wiring schematic with phase connection to G203V drives. Been lurking awhile, haven't found a straight forward diagram. Thank You

[scottly]

Which motors do you have? The Superiors or the Sigmas?

[kosmo]

I have the Sigma motors

[scottly]

Connect motor terminals 1&5 to /A

Connect motor terminals 3&6 to A

Connect motor terminals 2&7 to /B

Connect motor terminals 4&8 to B

(If the motor runs in the wrong direction, switch the A and /A leads)

Thanks! I actually found this setup on another post but was looking for clarification. Would this be a parallel wiring ?

[scottly]

Yes, this would be a parallel connection: the coil with leads 5&3 is in parallel with the coil with leads 6&1, and the coil with leads 7&4 is in parallel with the coil with leads 8&2.

I am also using my old bridgeport steppers and Gecko 203V's. How can you the differance between Sigma and Superior motors? Is the wiring that different?

Thanks for the Help.

[scottly]

The terminals on the end of the motors are arranged differently; this makes it easy to tell the difference. The attached pics are scanned from the BP wiring diagram.

oops!

[Myk Bates]

Wow! Good fast information. Thanks for the reply scottly.

[scottly]

You're welcome! If you have the superior motors, I do have some info on parallel bi-polar wiring, but I have not verified it. It is completely different from the sigma wiring.

I keep reading about parallel and series wiring but I dont know enough to know why you would do one and not the other. Does it matter? Is there a place on cnczone that explains this more. I dont want to hijack this thread.
