MSD 542 drivers
Routout CNC 25 way D BOB
Now i understand its best to wire this in Bipolar parallel, but thats all i know. I have got diagrams and i still don't get it. Can some one please do me a simple,easy to read diagram, walk through etc. Because at the moment i'm :confused:
am i right in thinking the motors wires would be paired as

The Following User Says Thank You to Jonathan For This Useful Post:
[QUOTE=Jonathan;25682]No...that's a short circuit
A+ = Red + Blue/White
A- = Red/White + Blue
B+ = Green + Black/White
B- = Green/White + Black
Bipolar series gets better torque at very low speed, so it's not much use for you.
I think i understand it now, so should the B+ and B- colours be switched?

If you reverse A+ A- or B+ B- you reverse the motor.
That's in parallel, by all means try series and let us know the difference.
Put your motors in parallel then see if you can get 25mm/s :naughty:
(No DON'T do that, just kidding)

If i follow the colours on this data sheet, the A+ A- match up, but the B+ B- seem reversed to the colours Jon posted. Am i reading it wrong, i'm looking at the diagram bottom right

What I posted is fine - as Robin said if you swap A+ and A-, OR B+ and B- the motor will just spin the other way... i.e. if you change the current direction in either phase.
