Aux I/O Port Encoder Input
The Aux I/O Port provides an input for a differential
incremental encoder. This encoder is typically used as a
digitizing (read only) axis. This axis then acts as a
“master” axis, and the other servo axis are “slaved” to
its position. The Aux I/O Port encoder input accepts
RS422 differential inputs. The encoder signals should
be quadrature type. All encoder wiring between the
MMC and the drive should be shielded twisted pair as
shown in
