• Do not connect devices other than a USB memory device to the inverter.
• If a USB device is connected to the inverter via a USB hub, the inverter cannot recognize the USB memory device properly.
USB device communication
The inverter can be connected to a personal computer with a USB (ver. 1.1) cable.
Parameter setting and monitoring can be performed by using FR Configurator2.
Conforms to USB 1.1
Maximum 5 m
USB mini B connector (receptacle)
• For the details of FR Configurator2, refer to the Instruction Manual of FR Configurator2.
RS-485 terminal block
The RS-485 terminals enable 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
Communication can be performed with the Mitsubishi inverter protocol (computer link operation) and MODBUS RTU protocol.
For the details, refer to
