を切換えて表示するデジタル表示器で７セグメントの数
字表示器を４ケ並べて形成されている。The conventional inverter device is an inverter 1 whose input end is connected to a commercial frequency power source or a DC power source as shown in FIG.
The output terminal of is connected to the AC electric motor 2, and the output frequency is changed by the frequency setting device 3 to control the electric motor 2 at a variable speed. The operation monitoring is performed by the display device 4 provided in the inverter 1. As shown in FIG. 4, the display 4 is a digital display for switching between the frequency and the current value for display, and is formed by arranging four 7-segment numeric displays.
この表示装置は周波数と電流値が切換えて表示され、
同時に見ることはできないので、運転状態が充分に把握
できず、また周波数設定器を誤操作しても途中で誤りを
見出すことができないといつた欠点があつた。This display device displays the frequency and current value by switching,
Since they cannot be seen at the same time, the operating state cannot be grasped sufficiently, and even if the frequency setting device is erroneously operated, an error cannot be found on the way.
本考案は前記の欠点を除去し、簡単な表示装置で周波
数と電流値とが同時に監視でき、また周波数設定器を誤
操作した場合誤りに早く気がつくようにしたインバータ
装置の表示装置を提供することを目的とする。The present invention eliminates the above-mentioned drawbacks, and provides a display device for an inverter device, which can simultaneously monitor the frequency and current value with a simple display device and can detect the error quickly when the frequency setting device is erroneously operated. To aim.
本考案は周波数と電流値とを切換えて表示する表示器
以外に、周波数の最大設定値に対する現周波数の割合を
表示するレベルメータを設けるようにしようとするもの
である。The present invention intends to provide a level meter for displaying the ratio of the current frequency to the maximum set value of the frequency, in addition to the display for switching and displaying the frequency and the current value.

ータ等によつて安価にかつコンパクトに構成することが
できる。FIG. 2 shows an inverter device having a display device according to an embodiment of the present invention, and the same reference numerals as those in FIG. 3 are the same parts. The inverter 1 for variable speed controlling the AC motor 2 by the frequency setting device 3 has a display device 4 for switching and displaying the frequency and the current value, and a level meter 5 for displaying the ratio of the current frequency to the maximum setting value of the frequency. Installed. As shown in FIG. 1, the level meter 5 has a plurality of light emitting diodes (LEDs) 51 arranged diagonally to the upper right, and the ratio of the current frequency to the maximum set value is displayed depending on the number of lights. . Percentage can be displayed if 10 LEDs are provided. Such a level meter can be constructed inexpensively and compactly by using a comparator or the like.
レベルメータ５を設けることにより表示器４で電流値
を表示していても同時に周波数を監視することができ

タのLEDの点灯によつて誤操作に早く気が付くようにな
る。By providing the level meter 5, the frequency can be monitored at the same time even when the current value is displayed on the display 4. If the frequency setting device is erroneously operated, the LED on the level meter will light up so that the user can quickly notice the erroneous operation.
本考案によれば簡単な表示装置によつてインバータ装
置の運転監視が充分に行え、また周波数設定器の誤操作
が早く検知できるようになるので信頼性向上の効果があ
る。According to the present invention, since the operation of the inverter device can be sufficiently monitored by the simple display device and the erroneous operation of the frequency setting device can be detected quickly, the reliability is improved.
