The key switch 3 includes six touch panel type operation keys used for data display and mode setting. That is, the PRG / RESET key 31 is used to change the data display 2 from the monitor mode to the program mode and to return to the monitor mode. The FUNC / DATA key 32 is used for switching between a monitor mode for selecting a data type and a function code data mode for instructing data write (write). The up key (Δ) 33 is used to increment data, and the down key (▽) 34 is used to decrement data. The RUN key 35 is a key for an operation command, and the STOP key 36 is a key for an operation stop command.
[0012]
The inverter device is switched to the monitor mode, the menu mode, and the function code mode by the key switch 3 described above. After the power is turned on, the monitor mode is initially displayed, and a physical quantity such as a motor speed controlled by the inverter device is displayed on the monitor. By pressing the FUNC / DATA key 32, the monitor type can be changed. The menu mode is switched by pressing the PRG / RESET key 31. In the menu mode, each item name of a large item, a medium item, or a small item can be displayed on the data display 2 one by one in a different display mode for each hierarchy to which the item belongs, as will be described below. .
[0013]
FIG. 2 is a diagram illustrating setting items that can be displayed in the menu mode.
In the menu mode, the main menu composed of the six major items shown in the item column of FIG. 2 and the submenu below the main menu are cyclically switched and displayed by the up key 33 and the down key 34.
