「v/f pattern」を含む例文一覧(1)
- This device has a V/F ratio drop rate setting part 13 that reduces V/F ratio until changeover conditions to the position detecting operation is met, and that supplies a V/F ratio decrement command to a V/F pattern setting part 14 to change the decrement of the V/F ratio in accordance with voltage range that holds the changeover conditions.
位置検出運転への切替条件が成立するまでＶ／Ｆ比を減少させるとともに、切替条件が成立する電圧幅に応じてＶ／Ｆ比の減少幅を変化させるべく、Ｖ／Ｆ比減少幅指令をＶ／Ｆパターン設定部１４に供給するＶ／Ｆ比ダウン量設定部１３を有する。 - 特許庁
