A-2 Connecting To Encoder Input Terminals - Omron NJ501-1400 User Manual

A-2 Connecting to Encoder Input
Terminals
This appendix describes connections to an OMRON GX-series EtherCAT Slave Encoder Input Termi-
nals.
A-2-1 Wiring to Encoder Input Terminals
Encoder Input Terminals are connected using EtherCAT communications. Refer to the NJ-series CPU
Unit Built-in EtherCAT Port User's Manual (Cat. No. W505) for information on the connection methods.
A-2-2 Settings for Encoder Input Terminals
This section outlines the Encoder Input Terminal settings that are used when connected to OMRON
GX-series GX-EC0211/EC0241 Encoder Input Terminals (i.e., the applicable Encoder Input Terminals
for the MC Function Module). Refer to the GX-series EtherCAT Slave User's Manual (Cat. No. W488)
for detailed information on the Encoder Input Terminals.
Recommended Encoder Input Terminals
All of the functions of an encoder axis of the MC Function Module can be used for Encoder Input Termi-
nals with the unit versions that are given in the following table.
Manufacturer
OMRON
OMRON
Additional Information
• Only the OMRON GX-EC0211/EC0241 can be used for encoder axes of EtherCAT slaves.
• Unit version 1.0 of the GX-EC0211/EC0241 can also be used for encoder axes, but they do
not support the Sysmac device functions. When you use unit version 1.0, do not set the node
address switches to 00. If you set them to 00, a network configuration error occurs. Refer to
the GX-series EtherCAT Slave User's Manual (Cat. No. W488) for detailed information on
functions
External Input Signals
When all of the functions of an encoder axis are used for an Encoder Input Terminal, the following input
signals are used at the Encoder Input Terminal.
• Counter A phase
• Counter B phase
• Counter Z phase
• Latch Inputs (A/B)
There are two counter channels, and there are two external latches for each channel. Wire the input
signals that are required for your application.
Refer to the GX-series EtherCAT Slave User's Manual (Cat. No. W488) for input signal wiring methods.
