John, have you played with these drivers before?

Yes used quite a few of them, got a pick a new batch up tomorrow from Ketan at ARC now he's had another container come in.
Pre ordered 20 but he ran out and sold the ones he'd put on one side for me.

So I'll play safe and get 30 or 40 of them this time.

Everything is working now, i get forward and backward movement with the pins set up the way i told you, everything seems to be working as it should.

Good!

Just been reading that manual and it looks like you can remove the GND wires from the PUL- and Step- if you are still having issues.

Excerpt from PM542 manual -

This driver uses differential inputs to increase noise immunity and interface flexibility.

Single-ended control signals from the indexer/controller can also be accepted by this interface.

Still does not make sense but if its working then don't mess with it too much!

[D-man]

Steve i will remove the GND wire and let you know the outcome..

[D-man]

Steve there is no step- on the divers

[HiltonSteve]

Steve there is no step- on the divers

Sorry I meant PUL- and DIR-

[D-man]

done what you mentioned but if i do that nothing works at all. could that effect the pin situation?

[HiltonSteve]

Just sent you a PM

Disconnecting the - side of the clock, direction and enable will mean that the optos dont work, and you will get no motion.
