Communication operation
• Using the PU connector 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).
(For details, refer to the Instruction Manual (Detailed) of the FR-A860.)

• Different inverter data can be saved in a USB memory device.
The USB host communication enables the following functions.
Function
• Copies the parameter setting from the inverter to the USB memory device. A maximum of 99 parameter setting
files can be saved in a USB memory device.
• The parameter setting data copied in the USB memory device can be copied to other inverters. This function is
Parameter copy
useful in backing up the parameter setting or for sharing the parameter setting among multiple inverters.
• The parameter setting data copied in the USB memory device can be saved in a personal computer and edited
in FR Configurator2.
• The monitored data and output status of the signals can be saved in a USB memory device.
Trace
• The saved data can be imported to FR Configurator2 to diagnose the operating status of the inverter.
• This function copies the PLC function project data to a USB memory device when the PLC function is used.
PLC function data • The PLC function project data copied in the USB memory device can be copied to other inverters.
copy • This function is useful in backing up the parameter setting and for allowing multiple inverters to operate by the
same sequence programs.
• The operating status of the USB host can be checked on the LED display of the inverter.

OFF No USB connection.
ON The communication is established between the inverter and the USB device.
Fast blinking The USB memory device is being accessed. (Do not remove the USB memory device.)
Slow blinking Error in the USB connection.
• When a device such as a USB battery charger is connected to the USB connector and an excessive current (500 mA or
more) flows, USB host error (UF warning) is displayed on the operation panel.
• If a UF warning occurs, disconnect the USB device and set Pr.1049 = "1" to cancel the USB error. (The UF warning can
also be canceled by resetting the inverter power or resetting with the RES signal.)
