Spindle not running - Need Help

[Doddy]

So, assuming you're running Mach3, can you enter an MDI command "M3 S18000" and the VFD (the black box connected to the spindle with the red 7-segment display) will display "F300.0" and indicate the "For" LED?, and the Spindle still refuses to spin?

I have entered the code into mach3. the spindle speed bar is flashing yellow which happens when the spindle is moving.
The code on the VFD is showing A0000


Thanks again for your help with this
