Allen-Bradley is the brand-name of a line of factory automation equipment owned by Rockwell Automation.The company, with revenues of approximately US $6.4 billion in 2013, manufactures programmable logic controllers (), human-machine interfaces, sensors, safety components and systems, software, drives and drive systems, contactors, motor control centers, and systems of such products.
According to the Guinness Book of World Records: "The largest four-faced clock is that on the research and office addition of the Allen-Bradley Company. Each face has a diameter of 40 feet 3 + 1 ⁄ 2 inches (12.28 meters), and is octagonal to represent the outline of the Allen-Bradley logo. Dedicated on October 31, 1962, it rises 280 ft (85 m ...
Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
It was founded by Dr. Stanton Allen and Lynde Bradley with an initial investment of $1000. [2] In 1904, 19-year-old Harry Bradley joined his brother in the business, and the company's first patented product, a carbon disc compression-type motor controller for industrial cranes, was demonstrated at the St. Louis World's Fair the same year. In ...
Motor-CAD is an Electromagnetic and Thermal analysis package for electric motors and generators, developed and sold by Motor Design Ltd. It was initially released in 1999. Modules are available for brushless permanent magnet motors (BPM), outer rotor BPM motors, induction motors, permanent magnet dc machines, switched reluctance motors ...
In a properly configured control system, the servo motor rotates at a velocity that very closely approximates the velocity signal being received by the servo drive from the control system. Several parameters, such as stiffness (also known as proportional gain), damping (also known as derivative gain), and feedback gain, can be adjusted to ...
Sercos I and II are standardized in IEC 61491 and EN 61491. Sercos III is specified in standards IEC 61800-7; IEC 61784-1, -2, -3 and IEC 61158. Sercos is designed to provide hard real-time, high performance communications between industrial motion controls and digital servo drives.
Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems , and was based on GRAFCET [ fr ] (itself based on binary Petri nets [ 1 ] [ 2 ] ).
