• Different inverter data can be saved in a USB memory device.
The USB host communication enables the following functions.
• When the inverter recognizes the USB memory device without any problem, " " is briefly displayed on the
operation panel.
• When the USB memory device is removed, " " is briefly displayed on the operation panel.
• The operating status of the USB host can be checked on the LED display of the inverter.
• 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.)
NOTE
• 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.
• For the details of usage, refer to the FR-A800 Instruction Manual (Detailed).
