NX-series Incremental Encoder Input Unit NX-EC0 CSM NX-EC0 DS E 6 5 Read position information from incremental encoders, synchronised with the control cycle and EtherCAT Distributed Clock. 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. Features Open collector output type and line driver output type Incremental Encoders can be connected. 1 High-speed remote I/O control with communications cycle as fast as 125 s.* 2 Free-Run refreshing or Synchronous I/O refreshing, Task Period Prioritized refreshing* , can be selected for refreshing with the NX-series EtherCAT Coupler. When the MC Function Modules of the NJ/NX-series Machine Automation Controller are used, the encoder input can be used for motion control instructions as an axis. Latch function (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) Input edge time stamps The maximum and minimum counter values can be set. *1. When using the NX-EC01 together with the NX701- and NX-ECC203. *2. Task Period Prioritized refreshing is available when the NX-ECC203 is used together. System Configuration Support Software (Sysmac Studio) EtherCAT master (NJ/NX-series CPU Unit) Connection to the peripheral USB port TM or built-in EtherNet/IP port on an NJ/NX-series CPU Unit EtherCAT communications cable Incremental Encoder Input Unit EtherCAT Coupler Unit I/O power *1 External input supply (latch input 1, latch input 2, gate input, or reset input) Incremental encoder *1. You can specify functions for up to two external inputs to a One-input Incremental Encoder Input Unit. You cannot use external inputs for a Two-input Unit.
