Chapter 2: Installation and Configuration
2.4.1.1. Square Wave Encoder
The XR3 accepts RS-422 square wave encoder signals. The XR3 will generate a feedback fault if it detects
an invalid signal state caused by an open or shorted signal connection. Use twisted-pair wiring for the
highest performance and noise immunity.
