Resetting Usb Host Errors; Multiple Rating Setting - Mitsubishi Electric 800 Series Instruction Manual

5.7.7

Resetting USB host errors

When a USB device is connected to the USB connector (connector A), the USB host error can be canceled without
performing an inverter reset.
Pr. Name

USB host reset
E110
• 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
• 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

Four rating types of different rated current and permissible load can be selected. The optimal inverter rating can be
chosen in accordance with the application, enabling equipment size to be reduced.
