Motor driver differential interface schematic
Optocoupler input is the best available option in terms of resistance to interference and
convenience of connection. For each signal, twisted pair of cables is needed.
If motor driver has optocoupler inputs then there is no need to connect GND of the devices too.
Signs on the drive may differ so you should first read the documentation carefully. It can be e.g.
PUL+/PUL- and SIGN+/SIGN-, however it is not a rule. Servo drives often have two different
types of STEP/DIR inputs.
There is connection variant with shared (common) GND wire. This variant (most Gecko micro step
drivers) is a little bit worse because of lower interference resistance and it is a bit more difficult to
connect.
