Description
時刻t3でオペレータが操作装置14の操作を再開した場合、レバー操作は「操作あり」になり、ローアイドル制御器26Aはアイドル状態フラグを「セット」から「クリア」に切り換える。また、回転数制御器26Bは、回転速度指令をローアイドル回転数から設定回転数に切り換えて、エンジン回転数を回転数指示装置27による設定回転数まで上昇させる。これにより、ゲート制御器24は、インバータ23のスイッチング状態を「ON」に戻し、メインコントローラ26からの制御指令に応じてアシスト発電モータ10を駆動させる。これにより、油圧ショベル1の動作に支障なく、アシスト発電モータ10を駆動させることができる。
