Abstract:
A servomotor driven machine under control of a control system is disclosed that incorporates a diagnostic system for early detection of the need for service thereby allowing for preventive maintenance to avert machine failure. The control system includes a servomotor (90) that drives a movable component of an apparatus. A controller (20) is provided for directing the movements of the servomotor (90) in accordance with a predetermined motion profile. The controller (20) monitors torque load on the servomotor (90) within a predetermined time frame and compares the monitored torque load with one or more predetermined service torque values to determine whether a service condition exists that requires maintenance. A status indicator responsive to the detection of a service condition by the controller (20) is employed to provide an indication of the service condition to, for example, an alphanumeric or graphic display (205) or printer (215), a central computerized maintenance scheduling system (230), and/or an automatic maintenance system.
Abstract:
A computerized numerical control system (200), is provided for controlling a servomechanism (210 and 215) under the direction of a general-purpose computer system (220). The system implements in software a PID controller for determining appropriate inputs to the servomechanism (210 and 215). The system further includes a Field Programmable Gate Array which is loadable with custom logic for remotely interfacing to the servomechanism (210 and 215).
Abstract:
Lorsque chacun des blocs de fonctions d'une unite de commande numerique transmet et recoit des signaux d'une unite de traitement d'ordinateur (MPU) par l'intermediaire d'un bus d'adresse (ABUS) et d'un bus de donnees (DBUS) des registres a decalage (SH1), (SH2) convertissent un signal parallele en un signal en serie, des dispositifs de transmission (TX11), (TX12) convertissent un signal electrique en un signal optique et transmettent le signal optique a un dispositif de distribution d'impulsions (PON) de chaque bloc de fonctions par l'intermediaire de cables de fibres optiques (OF1), (OF2), des dispositifs recepteurs (RX3), (RX4) retransforment ensuite le signal optique en un signal electrique, apres quoi des registres a decalage (SHR3), (SHR4) retransforment le signal en serie en un signal parallele, et le signal parallele est envoye a un dispositif de distribution d'impulsions (PD) en tant que signal de position correspondant aux coordonnees X, Y et Z d'une machine outil afin d'entrainer un servo-moteur.
Abstract:
The present invention concerns a mosaic module (100) for a control panel of a power plant, the control panel comprising a plurality of mosaic modules (100) being arranged adjacent to each other, each mosaic module being adapted to be fixed to a mechanical support structure, the mosaic module (100) comprising: at least one display device (110) for displaying a function of the power plant and/or an input device (112); at least one optical power supply input (122) for receiving a power supply for the mosaic module (100) via one or more first optical links (320), and at least one optical data input (102) for receiving data to be displayed on the display device (110) and/or at least one optical data output to transmit an input command received from the input device.
Abstract:
A reliable, expandable robot control system requiring less maintenance. A main controller (1) and a controller (2) control a manipulator (4) that operates with a servomotor. Communication means (5) is provided for data communication between the main controller (1) and the auxiliary controller (2). The main controller (1) is connected through communication means (7) to a centralized controller (3), which performs total management and control of a plurality of robot controllers connected with it.
Abstract:
A thermal processing system includes a thermal torch for processing a workpiece, a power supply for providing power to the thermal torch, a positioning system for relatively moving the thermal torch and the workpiece, a controller for controlling the thermal processing system, and a deterministic-based. communication network, such as, for example, a network which operates using SERCOS. The deterministic-based communications network connects at least the controller, the power supply, and the positioning system of the thermal processing system together.
Abstract:
A control device for controlling robots is divided into a servo amplifier, a strong electric current unit (3) such as a power supply, which supplies the servo amplifier with electric power, and a control unit (1) of an information processing system except the servo amplifier and the current unit. The strong electric current unit (3) is adjacent to or housed in a robot mechanism unit (2). The control unit (1) is installed outside a safety fence (4). The control unit (1) and the servo amplifier of the strong electric current unit (3) are connected to each other by an optical fiber cable (5). Since the control unit (1) is outside the safety fence (4), it is easy to perform operation and maintenance of robots. Also, the optical fiber cable (5) performs high-speed serial communication, only a single cable is required to reduce an occupied space.
