While these boards are designed to work with VFD inverters, they can work
with many DC motor controllers. More information is needed before I can
tell if it will work with yours. Please post a manual, a link to the manual,
or at least a make and model number if you want additional help.
The PMDX-107 is designed to mate directly with a PMDX-126 or PMDX-132,
thus making the wiring simpler. The PMDX-106 has extra relay contacts
and inputs for manual mode control. Basic functions are the same for
both boards.
These boards require a PWM signal for control. They cannot accept step
and direction (pulse repetition rate) for speed control. Mach3, despite
the fact that you must set pin numbers as if they were step and direction,
actually will output PWM as needed.
