• Connection of Several Inverters
Factory Automation can be applied with several inverters which share CC-Link system as a
remote device station, and are controlled and monitored by PLC user programs.
Master unit
DA
Termination
resistor
DB
110 ohm, 1/2W
DG
(130 ohm, 1/2W)
SLD
FG
Ground
(100 ohm or less)
* Maximum number of units connected to one master station is 42 units (when only inverters
are connected).
* If any other units are included, the number of occupied stations depends on the unit. So the
connectable number of units is different.
Communication terminal DA, DB
*
Set up the network using shielded twisted pair cable.
* Communication terminal DG
* Shield connection terminal SLD
Please connect the shield line of the dedicated CC-Link cable with the SLD terminal.
* Connection of the frame ground terminal FG
Grounding resistance is 100 ohm max.
* Termination resistor
Use the termination resistors supplied with the PLC or use a commercially available
110 ohm, 1/2W resistor.
Note : Please use 130 ohm, 1/2W resistors when use the high performance CC-Link
(
dedicated cable.)
