To easily specify a faulty place in a power supply line in a system for supplying a supply voltage from a common power supply circuit to a plurality of encoders.SOLUTION: An encoder system includes: an encoder power supply circuit 12 for generating a supply voltage; an individual power supply line 54 that is provided for each encoder 52 for supplying a supply voltage and allows its one end to be connected to the encoder; a switch 22 that is provided in the other end side of its individual power supply line 54 for each individual power supply line 54 and switches connection and disconnection to the encoder power supply circuit 12; and a voltage detection circuit 23 provided in a side of the encoder 52 rather than the switch 22 in the other end side of its individual power supply line for each individual power supply line 54.SELECTED DRAWING: Figure 1 【課題】共通の電源回路から複数のエンコーダに電源電圧が供給されるシステムにおいて、電源配線における障害箇所を容易に特定することができるようにする。【解決手段】電源電圧を発生するエンコーダ電源回路１２と、電源電圧を供給するためにエンコーダ５２ごとに設けられて一端がそのエンコーダに接続する個別電源配線５４と、個別電源配線５４ごとにその個別電源配線５４の他端側に設けられてエンコーダ電源回路１２への接続と切放しとを切り替えるスイッチ２２と、個別電源配線５４ごとにその個別電源配線の他端側においてスイッチ２２よりもエンコーダ５２側に設けられた電圧検出回路２３と、を設ける。【選択図】図１
