The only relay present on the control board is apparently the external reverse signal. There is a page in the parameter menu that can switch that around some. That front panel in the EXOROR manual bears only a style resemblance to that front panel, but the booklet that came with it seems to work exactly, so its relatively easy to locate a parameter and change it. See below the next paragraph for a question that Peter or John T. might be able to asnwer. Now, I may have changed my mind about it, I just now had it running at 100hz/6000 revs, and with a .5 second accel time set, and a .5 second decel time set, then hit the run button, and its 6000 grand right now, hit the fwd/rev button and its within or right on, that 1 second total to reverse itself, violent enough it unscrewed the collet nut several turns. But I've got a bunch of guys in the basement, installing wall 4" I beam wall braces on the front wall, and digging a ditch nearly to the footer for a water drainage lashup. So with all the extra getting around, I'm ready to pronounce that its beer thirty and I'm my usual one behind. Now, this thing can talk over a serial port, and it may be able to change parameters on the fly. But ATM I don't think I have a seriel port without adding a card. So, is there a way I can excise the spindle controls I do now, in favor of shipping the data back and forth over a serial port, using a few pins on the 26 pin idc header on a 5i25? What I'd have in mind is finding out what it can do at the bottom of the speed range, and what sort of a scale to send it to give it more time if I'm going to ask for the higher speeds, setting up something that amounts to if its 100 hz faster, gets double the time it needs at 50 hz. Yadda tadda. ditto for stop times, making it do what it can do for turnaround times w/o tripping itself off at any speed. I don't know what it will ultimately do, but so far I haven't caused a trip-off with my playing from its control panel. And I have managed to get it to reverse in what I'd have to say is a timely, usable manner. The only error I've seen is a UV error, for about 20 seconds after I killed the breaker.
