Encoder Feedback Signals EA, EB and EZ
The encoder feedback signals include EA, EB, and EZ. Every axis
has six pins for three differential pairs of phase-A (EA), phase-B
(EB), and index (EZ) inputs. EA and EB are used for position
counting, and EZ is used for zero position indexing. Its relative sig-
nal names, pin numbers, and axis numbers are shown in the fol-
lowing tables:
The input circuit of the EA, EB, and EZ signals is shown as fol-
lows:
