I have a cnc ethernet controller for stepper motors. The controller signal outputs are step, direction and common +5 for signal return. However, The stepper motor drivers I have take inputs that are step, direction and common signal ground. Is there a circuit that I can use to convert the cnc interface common +5 to common signal ground?
Its a chinese ethernet interface card NVEM v2 \. There is much help except that the outputs for each driver are +5, step pulse, direction pulse. And the step motor drivers are common signal ground, step pulse direction pulse. See the Geckodrive G540 .
It does look at section 2.2.1 then how it connects to a stepper motor driver in figure 2.3 But my drivers also have opto isolators and they require common signal ground. The NVEM shows +5 as the signal return path.
