Thanks for all of the quick replies!

During the retrofit, I removed a D to A converter and hooked the speed command directly to the Galil card. I assume that somehow the D-A converter had an inverted output. That is my only guess as to how it got this way.
The drive is a Contraves Compact Series 200 ADB/F. I have an operating manual for it, but it doesn't refer to any method of reversing the direction sense.

Thanks, but I am afraid I don't understand what you are trying to show in the graphic you posted.
Al:
From the drive, I have two connections going to the field, two going to the armature, and two for the tachometer. I guess that swapping the field pair would serve to reverse the field relative to the armature?
The drive has a +/- 10V analog input. There is not a separate reversing input.
I assume this means there is no software setup in Camsoft to reverse the spindle? |
