Overview

Omron NX Family of Series | NX-EC — Incremental Encoder Input Unit:

Read position information from incremental encoders, synchronized with the control cycle and EtherCAT Distributed Clock. The process encoder input data using the MC Function Modules of the NJ Series Machine Automation Controller. The time when the encoder input value is changed can be read. This enables high-precision timing control in combination with time-stamp outputs.

Series Features:

Open collector output type and line driver output type Incremental Encoders can be connected

High-speed remote I/O control with communications cycle as fast as 125 μs*1

Free-run refreshing, synchronous I/O refreshing, or task period prioritized refreshing*2 with the NX1P2 CPU Unit or EtherCAT Coupler Unit

The MC Function Modules of the NJ/NX/NY5 Controllers allows the encoder to be used as a motion axis

Latching (1 internal signal and 2 input signals from external devices)

Pulse Period Measurement

32 bit counters (80000000 to 7FFFFFFF HEX)

Maximum counting rate: 4 MHz (Line receiver: 4 MHz, Open collector: 500 kHz)

Time Stamping

Maximum and minimum counter value setting

Connect to the CJ PLC using the EtherNet/IPTM bus coupler
