What happened to the motor that was controlled by the step motor drive
The step that you give is in one direction and you're going to give the other step in reverse For example, if you give 1010 you want to change to 0101
You don't pick up the signal line, you pick up the signal and you get the DRI - and the DRI +I hope my answer will help you
There is no direction signal, and the 5V power supply goes through a 1K resistor to the DRI +, the negative electrode of the DRI. DRI - and DRI + power are in one direction, and power cuts are in the other direction.
