The signals connection and relative circuit diagram is shown in the following diagram. The external limit switches
featuring a contact capacity of +24V, 6mA minimum. An internal filter circuit is used to filter out the high
frequency spike, which may cause wrong operation. You can use either normal open switch or normal closed
switch by setting the DIP switch S1. The default setting is set as normal open type. See "Software Manual for the
DMC5400 Motion Controller" for more detail operation of the EL.

4.5 Encoder Feedback Signal 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) inputs. The EA and EB are used for position counting, and the EZ is
used for zero position index. The relative signal names, pin numbers and the axis number are shown in the
following tables.
