Thank you for the help with 234 spindle cable fault. I cleaned the connector on the spindle encoder, and the wiring harness connector. Has stopped doing that for now. When I power up the machine (VF3), after power up, say 30 secs to 1 minute, get a motor overheat, or A motor overheat, for 1/2 second then changes to 112 no interupt. This locks up the display. The second power up might be for 2-5 minutes before this happens. Then it might do it 2-4 more times, or not. Then I have run machine for 1/2 hour, to finish what ever I was doing, with no problems. Any help would be appreciated. Stephen
