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 inventer parameters through
communication via RS-485 .
1) Mitsubishi general-purpose inverters FREQROL F700, A700, E700,
V500, F500, A500, E500 and S500
(containing the communication type) Series can be linked.
(F700, A700, E700, V500 and F500 Series inverters can be connected only to FX
3U and FX3UC PLCs.)
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).
