Does anyone have a schematic for a 402-5001-022 Servo Amp for a Hurco KMB1?
I fired KMB1 up the other day, and as soon as I powered up the servo's the z axis retracted HARD and will not move in the (-) direction. I swapped cards with Y, and the problem moved to Y.
I'm fairly comfortable with trouble shooting pcb's to component level, but I need a schematic. I sure hate to pay $700 - $1K for a repair or replacement board... when I know it's probably a $5 component on this board causing the problem.
Anyone out there have a schematic (or, better yet) anyone have experience with this type of problem and can possibly tell me what the problem is.
I would appreciate any pointers, advise...Suggestions.
