Connection Of Several Inverters - Mitsubishi Electric 800 Series Instruction Manual

3.3

Connection of several inverters

An inverter can join the link system as a CC-Link remote device station, and such device stations can be controlled and
monitored with a user program of a programmable controller. These devices can be useful components of an automated
factory.
Connect shielding wires of the CC-Link dedicated cable to "SLD" of each unit.
Terminating
resistor
*1 Use the terminating resistors supplied with the programmable controller.
*2 Set "1" and "2" of the terminating resistor selection switch to OFF (without terminating resistor) in the middle units. (Refer to
*3 Set the terminating resistor selection switch. (Refer to
Do not use the built-in terminating resistor selection switch when using a one-touch connecter plug with terminating resistor. (1-OFF, 2-
OFF) (Refer to
 Maximum number of units connected to one master station (CC-Link Ver.1.10)
 42 units (when connections are inverters only)
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 c: Number of units occupying 3 stations
b: Number of units occupying 2 stations d: Number of units occupying 4 stations
{(16 × A) + (54 × B) + (88 × C)} ≤ 2304
A: Number of remote I/O ≤ 64
B: Number of remote device stations ≤ 42
C: Number of local, standby master and intelligent device stations ≤ 26
