Abstract

A copy source inverter includes a parameter-information transmission controller that reads parameters stored in a storage area and causes a USB host controller to transmit the parameters to a copy destination inverter when the inverter is connected to the copy destination inverter. The copy destination inverter includes a parameter-information reception controller that stores the received parameters in a storage area included in the inverter when the parameters transmitted from the copy source inverter are received via a USB slave controller included in the inverter.

Claims

1. An inverter system comprising a plurality of inverters that respectively include a storage area for storing a parameter for setting operations and are connected to each other according to USB communication standards, wherein

a first inverter as a USB host of the inverters includes a parameter-information transmission controller that reads parameters stored in the storage area of the first inverter and causes a USB host controller included in the first inverter to transmit the parameters to a second inverter as a USB slave of the inverters, when the first inverter is connected to the second inverter, and

the second inverter includes a parameter-information reception controller that stores the received parameters in the storage area included in the second inverter when the parameters transmitted from the first inverter are received via a USB slave controller included in the second inverter.

2. The inverter system according to claim 1, wherein

the first inverter further includes an operation-input receiving unit that receives a copy operation input for copying the parameters into the storage area of the second inverter, and

the parameter-information transmission controller causes the parameters to be transmitted to the second inverter when the first inverter is connected to the second inverter and the operation-input receiving unit receives the copy operation input.

3. The inverter system according to claim 2, wherein the copy operation input is power-on with a predetermined input button pressed.

4. The inverter system according to claim 1, wherein the storage area, the USB slave controller, and the parameter-information reception controller included in the second inverter operate with power supplied from the USB host controller.

5. An inverter that composes an inverter system comprising a plurality of inverters that respectively include a storage area for storing a parameter for setting operations and are connected to each other according to USB communication standards, wherein

a first inverter as a USB host of the inverters includes a parameter-information transmission controller that reads parameters stored in the storage area of the first inverter and causes a USB host controller included in the first inverter to transmit the parameters to a second inverter as a USB slave of the inverters, when the first inverter is connected to the second inverter, and

the second inverter includes a parameter-information reception controller that stores the received parameters in the storage area included in the second inverter when the parameters transmitted from the first inverter are received via a USB slave controller included in the second inverter.
