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:
Please note that the voltage across each differential pair of
encoder input signals (EA+, EA-), (EB+, EB-), and (EZ+, EZ-)
should be at least 3.5V. Therefore, the output current must be
observed when connecting to the encoder feedback or motor
driver feedback as not to over drive the source. The differential
signal pairs are converted to digital signals EA, EB, and EZ; then
feed to the motion control ASIC.
Below are examples of connecting the input signals with an exter-
nal circuit. The input circuit can be connected to an encoder or
motor driver if it is equipped with: (1) a differential line driver or (2)
an open collector output.
