Hi Hood
thinking about your code, it is the better solutions. It is the responsibility of the operator to restart the spindle. Ugly scratches on the surface of the workpiece is better than a burned spindle....
I'll keep you updated about my test results
one hint for the hardware (is working fine as suggested in my earlier post). Use a 100Ohm resistor for wiring the analog output signal to the analog input (place it on the input connector). The controller and the temperature sensor have both a 0-10V range, but if for some reason the 24V supply (e.g. short) is feed to the analog input, the internal clamping diode in the controller will protect the controller. The 100Ohm will limit the current in the clamping diode.
