Pin 31/47 and pin 17/33/50 are parallel and can be used alternatively.
* For encoders which do not permit all six signals, asymmetrical operation applies!
Encoders with only 3 signals must be connected to inputs X (pin 21), B (pin 4) and the
, ,,
zero marking pulse (pin 36).
Symmetrical operation
(incremental encoders)
(Improved noise immunity)
