How does the component get its spindle speed commands? I assume through the HAL pins? The diffeerence I see is that the Axis GUI sets motion.spindle-out to 1 and sets spindle-on and spindle-fwd to true as soon as you press the "fwd" button. An M3 command will set a much higher initial speed. Perhaps the VFD faults with such a small speed command? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
