We have a VF-2 (1997 with a Magnetek drive) that has recently generated two "123 Spindle Drive Fault" alarms.

One occurred during warm-up and the other while cutting a week later. Also, I heard a few click-like sounds from somewhere towards the back of the machine that I hadn't heard before.

When powering up the machine most recently, there were even more clicking sounds, at fast random intervals like a Geiger counter, so I shut it down. The clicks sounded like possibly a relay.

Does anyone have an idea what the clicking sounds might be from, and how they might relate to the 123 alarm?
