Thanks Al.
I would prefer not to do it in the M3 and M4, because I still want SPINFORWARD to actually spin forward.
I am not positive that the speed input on the drive is isolated (my documentation is not that good) and I don't believe that the Galil is either - they seem to use a common ground for everthing. I think I'd better play it safe here as well.
So it doesn't matter if I reverse the Field or the Armature, as long as I reverse the Tach as well. Is that correct? |
