To increase the degree of freedom in replacement and customization of control system parts of a rope-type elevator.SOLUTION: The safety control circuit for the unintended car movement protection is formed on one substrate so as to be replaceable and attachable as one module separately from a control board where a normal operation control circuit is installed, and includes multiple input connection parts and output connection parts, a storage unit for safety control storing predetermined multiple logic programs for operation abnormality determination including a logic program for door open running determination and storing logic program data for each operation abnormality determination, and an arithmetic processing device for safety control making an abnormality determination by processing a received signal according to the logic program for operation abnormality determination, and creating and outputting a car stop command signal which cuts off power supply to a motor electromagnetic contactor and a brake electromagnetic contactor connected to a power supply circuit based on the abnormality determination. The arithmetic processing device for safety control creates and outputs abnormality signals corresponding to each type of the abnormality determination when the abnormality is determined.SELECTED DRAWING: Figure 1

    【課題】ロープ式エレベータの制御系部品の交換やカスタマイズの自由度を高める。【解決手段】通常の運転制御回路が設置されている制御盤とは別体の独立した1モジュールとして、交換装着可能に一枚の基板上に形成されているものであり、1複数の入力用接続部と出力用接続部と、戸開走行判定論理プログラムを含む予め定められた複数の動作異常判定論理プログラム及び各動作異常判定論理プログラム用データが格納されている安全制御用記憶部と、動作異常判定論理プログラムに従って、受信信号を処理して異常判定を行うと共に該異常判定に基づいて電力供給回路に接続されたモータ用電磁接触器及びブレーキ用電磁接触器に電力供給を遮断させるかご制止指令信号を作成し出力させる安全制御用演算処理装置と、が含まれ、安全制御用演算処理装置は、異常判定が成された際に、異常判定の種類毎に対応する異常信号を作成して出力するものとした。【選択図】図1
