ACTUATOR CONTROL DEVICE

To provide an actuator control device capable of monitoring a communication abnormality between a control section and an external device by using a simple configuration.SOLUTION: An actuator control device 200 includes: a drive section 210 for driving an actuator 100; a control section 220 for controlling the drive section; an abnormality determination section 230; a first communication circuit 240 for relaying communication between an external device 300 and the control section; a second communication circuit 250 for relaying communication between the external device and the abnormality determination section; and a signal processing section performing conversion processing of a signal communicated via the first communication circuit. The abnormality determination section compares a first reception signal RS1 received from the external device via the first communication circuit with a second reception signal RS2 received from the external device via the second communication circuit, and determines whether or not an abnormality has occurred in the communication with the external device on the basis of a comparison result.SELECTED DRAWING: Figure 3 【課題】制御部と外部装置との間の通信異常を簡易な構成によって監視可能なアクチュエータ制御装置を提供する。【解決手段】アクチュエータ制御装置２００は、アクチュエータ１００を駆動する駆動部２１０と、前記駆動部を制御する制御部２２０と、異常判定部２３０と、外部装置３００と前記制御部との間の通信を中継する第１通信回路２４０と、前記外部装置と前記異常判定部との間の通信を中継する第２通信回路２５０と、前記第１通信回路を介して通信される信号の変換処理を行う信号処理部と、を備え、前記異常判定部は、前記第１通信回路を介して前記外部装置から受信した第１受信信号ＲＳ１と、前記第２通信回路を介して前記外部装置から受信した第２受信信号ＲＳ２とを比較し、比較結果に基づいて前記外部装置との通信に異常が生じたか否かを判定する。【選択図】図３
