Resetting USB host errors
• Parameter copy and the trace function can be used when a USB device (such as a USB memory) is connected to the USB
connector (connector A). (Refer to page 58 .)
• When a device such as a USB charger is connected to the USB connector and an excessive current (500 mA or higher)
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.)
5.7.8
Multiple rating setting
 Overload current rating and surrounding air temperature
• The overload current rating of the inverter can be changed by the Pr.570 setting.

30°C for the FR-A860-00090 or lower.

Changing the parameter initial values and setting ranges
• When inverter reset and all parameter clear are performed after setting Pr.570 , the parameter initial values are changed
according to each rating, as shown below.
When a USB device is connected to the USB connector (connector A), the USB host error can be canceled without
performing an inverter reset.
