INSTALLATION

2.6 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.

	Master module			FR-E5NC			FR-E5NC
Termination		DA			DA			DA	Termination
resistor*		DB			DB			DB	resistor*
		DG			DG			DG
		SLD Shielded twisted SLD				Shielded twisted SLD

		FG			FG			FG

*Use the termination resistors supplied with the PLC.

1)Maximum number of units connected to one master station 42 units (when only inverters are connected)

If any other units are included, the number of stations occupied depends on the unit and therefore the following conditions must be satisfied:

{(1 ⋅ a) + (2 ⋅ b) + (3 ⋅ c) + (4 ⋅ d)} ≤ 64

a:Number of units occupying 1 station

b:Number of units occupying 2 stations

c:Number of units occupying 3 stations

d:Number of units occupying 4 stations

{(16 ⋅ A) + (54 ⋅ B) + (88 ⋅ C)}	≤	2304
A: Number of remote I/O stations	≤	64
B: Number of remote device stations	≤	42
C: Number of local stations	≤	26
