3. CC-Link COMMUNICATION FUNCTIONS

3.2.2 Wiring method

(1) Communication connector
The pin layout of the communication connector CN10 on the MR-J2S-T01 option unit is shown below.
(2) Connection example
The servo amplifier and PLC CC-Link master unit are wired as shown below. Refer to Section 15.2.1
(3) for the twisted pair cable used for connection.
(3) Example of connecting multiple servo units
As the remote I/O stations of CC-Link, servo amplifiers share the link system and can be
controlled/monitored using PLC user programs.
