I have a KM3 with a problem. It has been working fine, but in the middle of boring a hole today, the spindle stopped. There was no particular fault right away, but within a few seconds and before I had a chance to shut it down, it got a z-axis motion error fault (not surprising).
Now, I cannot reset the servos. Even after a complete power cycling, I get no servo whistle when I hit Start. All of the fuses in the left cabinet are OK and I have good AC on all three legs. The magnetics do "clunk" as they should when I press Power and Start, but no whine.
In the right cabinet, on the servo amplifier board, the XFMR, +12, and -12 green LEDs are lit, but not the PBU LED. None of the yellow LEDs are on.
On the Control Relay Board, Fuse F1 is OK. For LEDs, I have:
DS1 (K1-COR): ON
DS2 (K2-SCRX): OFF
DS3 (K3-SOR): OFF
DS4 (K4-ATC/BCR): ON
DS5 (K5-SER): ON
DS6 (K6-CLV): OFF
DS7 (K7-REV): OFF
DS8 (K8-LTR): OFF
I cannot turn the spindle on and can't jog any axis.
Help?
