I'm finishing up the wiring on an axbb-e. The only thing i have left to get working is the spindle. It is an Allen Bradley ultra 3000 motor and drive. The input signals on this drive are 24v with 10.3v being the minimum. There is no option of low assertion (GND) signals for enable, step and direction. I'm not sure how to get the axbb-e to talk to this drive. Any suggestions?

1000 views and no comments? Well, here is where I'm at, Used a relay to be able to enable the drive via the axbb-e output. Also to enable a gear ratio preset within the Alen Bradley drive. Although as fast as the axbb-e can pulse, i don't think i'm going to need an electronic gear ratio. But i have not been able to get step and direction to work.
