Do not connect devices other than a USB memory device to the inverter. 1 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 2 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. 3 4 5 For details on FR Configurator2, refer to the Instruction Manual of FR Configurator2. 2.7.3 RS-485 terminal block 6 Communication operation 7 8 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 9 write parameters. Communication can be performed with the Mitsubishi inverter protocol (computer link operation) and MODBUS RTU protocol.
