Claims

[Scope of utility model registration request]

In an actuator set limit position stopping device that automatically stops a drive mechanism section of an actuator such as a valve drive device having a stroke end at a preset limit position, the stop position of the drive mechanism section can be remotely determined. A remote setting section for setting by operation is provided, and the drive mechanism section includes:
a memory that stores a setting signal transmitted from the remote control unit; a position detection unit that detects the current position of the actuator driven by the motor; and a detection signal of the position detection unit and the setting signal read from the memory. A central processing unit that constantly compares and outputs a stop signal when this detection signal matches or almost matches the set signal, and a switch that turns off in response to the stop signal from this central processing unit and stops energizing the motor. A set limit position stop device for an actuator, comprising:
