摘要： A system includes a sensor configured to monitor rotating machinery and generate a signal based on a physical characteristic of the rotating machinery. The system also includes a monitoring system with a processor. The processor of the monitoring system is configured to receive the signal from the sensor. The processor determines an occurrence of reverse rotation of the rotating machinery by comparing the signal to a normal operating pattern to generate an initial value. The processor generates a notification signal indicating the occurrence of a reverse rotation.

摘要： A garage door opening and closing apparatus having improved operational safety includes a control circuit which responds to a number of input stimuli to generate commands to open and close a garage door as well as to stop garage door movement. Three relays respond to the commands via drive circuitry to actually connect door operating voltages to the windings of a door controlling motor. By redundancies in the operation of the three relays, faults in the operation of those relays result in safe door operating conditions. Additionally, the control circuitry upon issuing a door stop command, performs a test to determine whether or not the door is still moving. If the door is still moving, door up commands are generated by the control circuitry to place the door in a safe position.

摘要： The invention relates to a monitor system for a servo controller used in connection with servo motors utilized in multivarious machines, such as machine tools. In addition to detecting a servo system fault when the difference between the commanded position and the actual position exceeds a predetermined value, the system monitors several servo system parameters to distinguish between different causes of servo faults. Identifying the source of the fault leads to improved maintenance and decreased system down time when a fault occurs.

摘要： Signals from a rudder position setting control and from a rudder position sensor constitute the only electrical information sources needed for operating a monitoring system for a rudder control that produces an alarm when the rudder control does not function effectively. The difference between the desired rudder setting and the actual rudder position, generated by a differential amplifier, is fed to a bi-directional limit circuit and a differentiating circuit is used to generate a signal corresponding to the rate of change of rudder position, which signal is likewise provided to a bi-directional limit circuit. The limit circuit outputs relating to the same polarity of error correction activate logic in an evaluation circuit so as to produce an alarm drive signal if the error signal exceeds the limit, while the rate of change of the rudder position signal for the proper direction of correction does not rise to the prescribed threshold, but the alarm generator is not enabled unless an error signal exceeding the limit persists for a predetermined period of time.

摘要： There are provided a load state diagnosis device and a load state diagnosis method for a servomotor. A PLC diagnoses the load state of the servomotor which rotationally drives a rotary tool in a predetermined rotational drive direction at a constant speed. The PLC includes a detection part that detects the rotational direction of a torque acting on the servomotor, a determination part that determines whether the rotational direction of the torque detected by the detection part is consistent with the predetermined rotational drive direction, and a load index output part that outputs a load index indicating the load state of the servomotor based on a determination result of the determination part.
