*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.)
