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-F800 Instruction Manual (Detailed).)
Terminating resistor switch
Initially-set to "OPEN".
Set only the terminating resistor switch of
the remotest inverter to the "100Ω" position.
