This chapter explains inverter communication.
1.1 Outline of System
Inverter communication allows connection between an FX PLC and up to eight inverters to monitor operations
of inverters, give various commands to inverters and read and write inverter parameters through
communication via RS-485 .
1) Mitsubishi Electric general-purpose inverters FREQROL F800, A800, F700, A700, E700, D700, V500,
F500, A500, E500 and S500 (containing the communication type) Series can be linked.
(FX and FX
2N
Series inverters.)
2) Inverter operations can be monitored, various command can be given to inverters, and parameters can
be read or written in inverters.
3) The total extension distance is 500m (1640' 5") maximum (for the system configured with 485ADP only).

Point
Inverter operations, reading/writing parameters, and monitor output can be performed with the PLC function
by writing a prepared sequence program to the inverter.
The inverter PLC function differs from the inverter communication function.
PLCs support only the A500, E500, and S500 (containing the communication function)
