FR-A800
5 - 625
●
Multiple inverters and 1 computer with RS-485 terminals
Make connection in accordance with the Instruction Manual of the computer to be used with.
Fully check the terminal numbers of the computer since they vary with the model.
For the inverter farthest from the computer, set the terminating resistor switch to ON (100 Ω side).
Two-wire type connection
If the computer is 2-wire type, a connection from the inverter can be changed to 2-wire type by pass-
ing wires across reception terminals and transmission terminals of the RS-485 terminals.

Connection to several inverter
NOTE
For branching, connect the wires as shown below.

2-wire type connection
NOTE
A program should be created so that transmission is disabled (receiving state) when the computer
is not sending and reception is disabled (sending state) during sending to prevent the computer
from receiving its own data.
