2.7.2 USB connector USB memory device 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 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.
When the UF warning appears, the USB error can be canceled by removing the USB device and setting Pr.1049 = "1". (The UF warning can also be canceled by resetting the inverter power or resetting with the RES signal.) 86 2.

communicat ewdriver, sh up the ion er, the USB host Interface Conforms to USB 1.1 orms to USB 1.1 Transmission speed 12 Mbps Wiring length Maximum 5 m Connector USB A connector (receptacle) Compatible USB memory Format FAT32 Capacity 1 GB or more (used in the recorder mode of the trace function) Encryption function Not available Function Description Refer to page Parameter copy • Copies the parameter settings 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 useful in backing up the parameter setting or for sharing the parameter setting among multiple inverters. • The parameter setting file can be copied onto a personal computer from the USB memory device and edited using FR Configurator2. 766 Trace • The monitoring data and output status of the signals can be saved in a USB memory device. • The saved data can be imported to FR Configurator2 to diagnose the operating status of the inverter. 668 PLC function data copy • This function copies the PLC function project data to a USB memory device when the PLC function is used. • The PLC function project data copied in the USB memory device can be copied to other inverters.
• This function is useful in backing up the parameter setting and for allowing multiple inverters to operate by the same sequence programs. 664 LED display status Operating status 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.
