my servo drive accepts rs 422 step signals(step+,step-), from pic micro controller i am giving pulses by converting to rs 422 using am26ls31
ic and giving the differential signal to the servo drive. my doubt is should i must connect the micro controller ground(0v) to servo ground(0v) (micro controller operating voltage 5v, servo drive operating voltage 24v). in rs 422 the transmitter and receiver ground must be same?
