  • Patent number: 6246916
    Abstract: This invention relates to a learning programmable limit switch for use in a motion system which provides passive feedback to a controller. The learning programmable limit switch is capable of causing the motion control system to operate in accordance with a user-programmed motion profile. The learning programmable limit switch provides the capability of accurately “learning” and controlling the positions at which a motion system changes velocity, as well as the timing at which the system causes a driven mechanism to, for example, stop. The system is intended for use in variable speed drives, hydraulic, pneumatic drive systems or any system where real time, passive feedback control is desired. In one typical environment, the learning programmable limit switch is connected to an output shaft of a driver. The outputs of the learning programmable limit switch are turned ON/OFF based upon the detected angular position of the output shaft.
