Communication operation
Using the PU connector or RS-485 terminal, you
can perform communication operation from a
personal computer etc. When the PU connector is
connected with a personal, FA or other computer
by a communication cable, a user program can run
and monitor the inverter or read and write to
parameters.
For the Mitsubishi inverter protocol (computer link
operation), communication can be performed with
the PU connector and RS-485 terminal.
For the Modbus RTU protocol, communication can
be performed with the RS-485 terminal.
For further details, refer to the instruction
manual (applied).
