I have been having a problem with my lathe "shutting down" from time to time and have needed to reset the button on my inverter. It has happened more and more lately and yesterday, it shut down and will not reset. The manual that came with the lathe suggests that if the spindle or motor stops, replace the motor. I fear there are a lot more electronic parts that come into play - like the inverter. How can I determine if it is the motor or the inverter that has the issues? The inverter is coding 000. Anyone know what that means? Thanks.
