EtherCAT Network Configuration
The EtherCAT network configuration consists of a Power Supply Unit, CPU Unit, End Cover, and EtherCAT slaves.
Use the built-in EtherCAT port on the CK3M-series CPU Unit to connect EtherCAT slaves.
EtherCAT is synchronized with the servo cycle of the CK3M-series CPU Unit. This enables acquisition of the I/O data of slave terminals that are
synchronized with the servo cycle.
F
CK3W-AD Unit
Analog Input Unit. You can add 4 or 8 voltage inputs.
G
