Chapter 4 Installation and Wiring EtherCAT port 4_ Wiring the Differential Input Terminals The direct-current signals in voltage 5 V can pass through the high-speed input terminals X0.0+~X0.1+, X0.0-~X0.1-, X0.8+~X0.11+, and X0.8-~X0.11- on AHxxEMC-5A. The frequency of input signals can be up to 1 MHz. These high-speed input terminals are connected to a differential (two-wire) line driver.
