Rs-422 Line Driver Encoder (Standard); Table 2-6: Encoder Specifications - Aerotech Ensemble LAB Hardware Manual

Installation and Configuration

2.3.1.1. RS-422 Line Driver Encoder (Standard)

The standard encoder interface accepts an RS-422 differential quadrature line driver signal. Invalid or
missing signals will cause a feedback fault when the axis is enabled.
An analog encoder is used with the -MXU or -MXR option (refer to
