ABSTRACT:
A servo motor system for a transportation line with the travel distance of the article predetermined and with a relatively low positioning accuracy. Basically, the system is constructed as an incremental servo motor system in which an incremental movement of the motor is detected, and the incremental movement signal is fed back to a motor driver, which also receives pulse signals from a controller corresponding to a traveling distance to a destination. Only one time after starting the operation of the servo motor system with the article not at the destination point, a stop signal is fed from an external signal generator located at the destination point to the motor driver, which stops the motor there. At this time, a coordinate system of the movable space of the article is established in the controller and the servo motor system is operated as an incremental system from the second time on, without utilizing an external signal generator.
