Connection cable
The RS-485 terminals enables 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 to monitor the inverter or read and
write parameters.
Communication can be performed with the Mitsubishi inverter protocol (computer link operation) and MODBUS RTU protocol.
(For details, refer to the FR-A800 Instruction Manual (Detailed).)
Terminating resistor switch
Initially-set to "OPEN".
Set only the terminating resistor switch of
the remotest inverter to the "100Ω" position.
