3.2 Encoder Feedback Signals EA, EB and EZ

The encoder feedback signals include the EA, EB, and EZ. Every axis
has six pins for three differential pairs of phase-A (EA), phase-B (EB) and
index (EZ) input. The EA and EB are used for position counting, the EZ
is used for zero position index. The relative signal names, pin numbers
and the axis number are shown in the following tables.

The input circuits of the EA, EB, EZ signals are shown as follows.

Please note that the voltage across every differential pair of encoder input
signals (EA+, EA-), (EB+, EB-) and (EZ+, EZ-) should be

at least 3.5V

or

higher. Therefore, you have to take care of the driving capability when
connecting with the encoder feedback or motor driver feedback. The
differential signal pairs will be converted to digital signal EA, EB and EZ to
connect to PCL5023 ASIC.

Here are two examples of connecting the input signals with the external
circuits. The input circuits can connect to the encoder or motor driver,
which are equipped with: (1) differential line driver or (2) open collector
output.
