Hi list Concept query; Looking at stepper drives, the general format seems to be 4 phases out, or Dir+Step, obviously saving two I/O lines. So why isn't a two phase signal used?. A 'quadrature' output? - you still use two lines - less worry about pulse duration - transmission line speed requirement is slightly eased as the lines step alternately - it applies equally to stepper or DC servo drives - there is no(or less) problem of timing error on direction reversal since the signal changes are 'slow' at this point Maybe this is common, or what did I miss?
