Yesterday while rigid tapping the tap bound up and generated an error. In my haste, I rebooted the machine and removed the tap without capturing the error. I thought maybe I'd bottomed out but it was actually maybe 3/4 depth. Now when I attempt to command the spindle it drops to EMG state without any error. I suspect it's generating an error but may be too fast to see. I've tried capturing it with my cellphone without any luck. It simply opens the contators and the hydraulic pump shuts down.
Is there an error log/history someplace?
