SV 1067 FSSB: Configuration Error (Soft)
SP 1999 Spindle Control Error
SP 1220 (S) No Spindle Amp
DS 0650 (B) Pole Detection Request
I found that the KM0 contactor is not pulling in and so no voltage is being supplied to the PSM. I believe all these alarms are related and that if I can solve the PSM incoming power issue it will likely correct all four alarms, but I am lost at this point. I am not an electrician and the wiring for the coil to pull in this contactor goes back to a printed circuit board. Any help as to what to check next would be greatly appreciated.
Thanks,
Brian
