I can turn on/off and adjust the speed of the spindle with Mach3. However, it seems that the spindle speed is somehow reversed.

Well...
Let’s say I put in M3S12000. The spindle starts right and spins. I believe the right frequency is 200 for this speed but it’s higher than that (can’t remember exact number right now). Now if I input S18000 while it’s running the frequency will lower (which it should go higher, right?) and the spindle “sounds” like it had decreased its rpm. And if I input S6000 the frequency jumps back up and the spindle sounds like a faster rpm (visually too).
Should I look for a setting in the VFD to be off or something in Mach3 settings (motor tuning, ports/pins, etc.)?
Thanks,
