Hello, I've been retrofitting an old lathe with LInuxCNC. An old 9-step electromagnetic gearbox was replaced with Toshiba VFS-11, old asyncronous servo motors got replaced with a couple of newer servos in position mode. Thus I use 5i25+7i76 on D525MW. First I successfully set up the VFD for manual 3 step gearbox, then I connected Z axis servo drive and it was jogging around pretty well.
The next day I powered up the PC and Z servo drive (but not VFD), the PC started booting. I remember the boot log appearing and then suddenly the screen gets black. Since then no picture from that PC, even no bios logo. I checked the display, the PSU etc with no success. It looks like the D525MW is dead. Pretty frustrating. Here's the first question: could it burn because of some electromagnetic issues? I used 12V from PC for 7i76 field power (is it wrong?). The (chinese) servo drive was connected to STEP/DIR in differential mode. The servo drive is supplied directly from 220V, but it has opto-isolated enable input, I connected it to GND and one of the field outputs. Later I took another D525MW which had been used with 7i43 + 7i48. But somehow this D525MW doesn't see the 5i25 board. I get "... hm2_pci.ko: No such device" error. lspci doesn't list 5i25. But the 5i25 lists on another PC and the config starts OK. The second question: what can be wrong with this D525MW?
