I don't think this will work I'm afraid.  This motor driver needs a PWM signal at a fairly high frequency, they say up to 10 kHz, to drive it.  This would normally be generated by the Arduino computer that it is designed to go with.  The recommended Mach 3 PWM signal is normally around 25 Hz and is designed to be smoothed to a variable dc voltage typically between 0 and 10 volts depending on mark/space ratio, which is compatible with standard motor speed controllers such as VFDs.  You can run Mach with a higher PWM frequency but the speed control would be very coarse.

ok let us talk about having on/off from mach3 and have the adjustment of the speed from  a variable resistance from outside connected to the pwm driver i think this is possible and enough

That might work, it has a 0-5v control input.
