A-3 Connecting to Encoder Input
Terminals
This appendix describes connections to an OMRON GX-series EtherCAT Slave Encoder Input Termi-
nals.
Encoder Input Terminals are connected using EtherCAT communications. Refer to the NJ/NX-series
CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) for information on the connection
methods.
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 Units User’s Manual (Cat. No.
W488) for detailed information on the 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.
• Only the OMRON GX-EC0211/EC0241 can be used for encoder axes of EtherCAT slaves.
• Unit version 1.0 of the OMRON GX-EC0211/EC0241 can also be used for encoder axes, but
they are not Sysmac devices. 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 Units User’s Manual (Cat. No. W488) for detailed information on func-
tions.
Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for details on
Sysmac devices.
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)
