All- My Sieg KC4S lathe conversion is moving along, and I have a question about driving a spindle motor controller using a Mesa 7i33 servo controller. According to the docs, that daughter card uses sign/magnitude mode , which will generate 0 to +10V analog out when the direction is positive and 0 to -10 V analog.
My problem is that the drive controller has a direction input and a speed input and the speed input is 0 to +10V regardless of direction. My thinking was that I could just tie the direction pin feeding to the 7i33 high and wire a different I/O pin to the direction input of the drive and tie that pin to the spindle direction. Unfortunately, I can't figure out how to tie the direction pin feeding the 7i33 to high. In the pncconf-generated configuration there is no explicit configuration that I can see tying the spindle direction to the direction pin expected by the 7i33. Am I missing something obvious or is there a different way to accomplish what I want? Thanks!
