Initial Design Check Please

Hi guys, ive still working on the build and doing all the wiring when i can, but i could do with some setup advice.

Im using AM882 drives and the following 4nm steppers (http://www.cnc4you.co.uk/Nema23-Step...m-60BYGH401-03)
I would like to know any general settings to make in the ProTuner software for the drives, as ill be configuring the alarm port setting so its always on and off in the event of a fault so i can daisy chain the alarms, and it will trigger a stop should a fuse go or a wire brake.

One question is i know its bad to unplug the motor from the drive while its running, but would it be bad to power the drive up with no stepper connected for setup purposes of the alarm circuit ect?

Many Thanks

No won't hurt it them at all.

Also Suggest you wire the alarms in parallel so if any one trips it turns on a relay. Put the E-stop thru a NC contact of that relay.
This means the relay will reset when power drops and the drives will reset them selfs. Also you'll avoid any issues with voltage drop wiring in series can give and it's less stress on the drive transistors.

I've powered the drives up with no steppers and it's not affected them...whether it's a right thing to do is another question :)

There is a check box as I had the same problem, Jazz told me about it and voilà the M6 codes worked....not near the router now so can't remember exactly where the option was....

That would be in General Config. See pic

Thanks guys I will have a look. Imy guessing a good test would be some basic wood engravingrain first?
