In cases where the driver (such as ClearPath) would only activate above a certain threshold due to the difference between the required and the provided signal from the control board due to the design of the driver/motor, the Puruvesi Automation carries line driver to 5V converters.
Their effect can be seen in the following diagram:
The ClearPath driver manual provides an explanation as to why their drivers are not directly compatible with 5V differential outputs, such as the ones used on the myCNC controller boards:
As can be seen, the input to the converter board is converted into a 5V output, which will allow the ClearPath (and similar) drivers to work properly.
Two methods of connecting the converters exist:
Either of these methods should work - it is left to the discretion of the user to pick the setup method better suited for their particular machine.
