This kind of VFD is a bit like stepper motor, it need step and direction to work.

You will need a frequency to voltage converter (CNC4PC) have some model.

it will transform the step frequency and convert it to the 0 to 10v necessary to get variable speed control. The more step, the more voltage = more RPM

You will also need another output for the direction that goes to a relay that will make contact between GND of the VFD to the FWD pin of your VFD.

But please take great care reading the manual, mine is like that and yours look to be similar but again read the manual carefully to be sure you're using the right pin.

Hi Toukas,

Welcome to the forum.

The easiest solution is to replace your breakout board with the C11 breakout board which has all the features you will need to connect your VFD with Mach. I also comes with all the instructions and connection details, you can view the details and manual here http://www.cnc4pc.com/Store/osc/product_info.php?products_id=161

Hope this helps.

Tweakie.
