*Connection of Several Inverters
Factory Automation can be applied to several inverters which share a link system as
CC-Link remote device stations and are controlled and monitored by PLC user programs.
◎ DA,DB
Shield twisted cable
◎ DG
◎ SLD / FG
Connect the shielded wire of the dedicated CC-Link cable to the “SLD” of each
module, and ground both ends of the shielded wire using type-D grounding (class 3
grounding) via “FG.”
(The ground resistance is 100Ω or less.)
◎ Terminal resistor
Connect the terminal resistor of 110Ω.
(130Ω is a resistance value for the CC-Link Ver.1.00 dedicated high performance cable.)
