My understanding is that you're never going to get a 100% correct voltage, but as you say, they are pretty close.
What this means, is that your Mach3 settings are correct, as The G540 is sending the correct voltage to the VFD.
The issue is that the VFD is not giving the correct speed that corresponds to the input voltage.
I've heard that better VFD's allow you to adjust this to compensate for voltage irregularities, but I don't know if yours does.
