摘要： PROBLEM TO BE SOLVED: To simply judge whether the trouble of the short circuit state of a controlling switch of a motor to make the lifting action of a stem exists or not by judging whether the trouble of the short circuit state exists or not from the current value of a detecting part of the motor controlling switch on the output side by making the motor controlling switch on in the input side ON. SOLUTION: At the time of inspecting whether the trouble of a motor controlling switch 10 exists or not, an inspection command signal of the motor controlling switch 10 is outputted. Therefore, off-command signal is outputted to each motor controlling switch 10, both motor controlling switches 10 are made off, and at the same time the brake action command signal is outputted to a brake circuit 13, the brake circuit 13 is acted, even if the rotation of inertia of a motor 3 exists, this rotation is stopped at once. In this state, whether the voltage value of a voltage detecting part 13a to detect the voltage applied to the motor 3 is 0 level or not is judged, when this is not 0 level, the motor controlling switch 10 of the input side is judged as the trouble of the short circuit state.

摘要： PROBLEM TO BE SOLVED: To provide a component supply device capable of realizing stable carriage and supply of parts. SOLUTION: This component supply device is furnished with a hopper 2 free to store a plurality of the components such as screws, etc., a carrier rail 4 free to carry the components stored in the hopper 2, an electromagnetic type vibrator 5 to vibrate the carrier rail 4 and a control means 6 to drive and control the vibrator 5 so that frequency at each part of the carrier rail 4 sequentially becomes proper frequency. Vibration of the carrier rail 4 sequentially and wavily changes to the side of a separate supply unit 9 from the side of the hopper 2. Consequently, it becomes possible to actually eliminate damping of vibration, generation of resonance, etc., on the carrier rail 4 and to stably carry and supply the components along overall length of the carrier rail 4.

摘要： PROBLEM TO BE SOLVED: To allow to communicate only with a specific outside equipment controller set in a personal computer. SOLUTION: In this communication method, a personal computer is provided with a programming tool for communicating with a sequential controller 1 which outputs a driving signal for driving a working unit, and an outside equipment controller side is constituted so that the identification information can be stored, and the personal computer side is constituted so that the identification information of the outside equipment controller can be read, and compared with preliminarily set identification information, and when they are made coincident, the program tool can be started. Thus, since the programming tool is made valid only for the sequential controller decided at the time of setting the working unit, and made invalid for the other sequential controllers an illegal use of the programming tool can be prevented. Also, the use of any old type programming tool can be excluded by changing the identification number each time when the version up of the operation program of the sequential controller is executed or the like.
