NX-series Incremental Encoder Input Unit
NX-EC0@@@
CSM_NX-EC0____DS_E_6_6
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.
• High-speed remote I/O control with communications cycle as fast as 125 μs.*1
• Free-Run refreshing or Synchronous I/O refreshing, Task Period Prioritized refreshing*2, 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.

The terminal number is identified by a column (A through D) and a row (1 through 8).
Therefore, terminal numbers are written as a combination of columns and rows, A1 through A8 and
B1 through B8.
For a 24-mm-wide terminal block, the left side contains terminals A1 through A8 and B1 through B8.
The right side contains terminals C1 through C8 and D1 through D8.
The terminal number indication is the same regardless of the number of terminals on the terminal
block, as shown above.

Applicable Wires
Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching ferrules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tool are given in the following table.
