That is normal and kind of safety feature so you can't jog the machine too fast without first changing the speed.
Well, it's working then.? The spindle won't spin unless you give it a speed. M3 is the start command, which turns on the Output which drives the Fwd command on the VFD, and S12000 is the speed. So if you type M3 or push the Start spindle button but haven't given it a speed so and it's at Zero speed then it won't spin but the Output will be active and the FWD command given to the VFD.
It's on the CNC drives website but why would you want to use Mach3.? It's shite compared to UCCNC and it's no longer supported.!-use common sense, if you lack it, there is no software to help that.
