Abstract
An operation detecting system for a fluid pressure actuator is provided with a first pressure sensor for detecting a first pressure value which is a pressure value in a first pressure acting chamber, a second pressure value which is pressure value in a second pressure acting chamber, and an operation detecting device including a detection program configured to calculate an addition value of the first pressure value and the second pressure value, calculate a time differential value of the addition value, and detect the start time and the stop time of movement of a piston based on a variation in the time differential value over time.
