PWM Base Frequency

On Figure 5-7, page 5-11 of Mach3 manual, under Motor Control, what numbers normally do you put for "PWM Base Frequency" and "Minimum PWM"?

I can't find this info anywhere in the manual

I think these values would depend on the hardware you are using but then again I have never used PWM so take that with a pinch of salt :)

PWM frequency is typically 50Hz.  Little to gain by going faster, and it can reduce resolution, depending on your kernel speed.
