Where the 'prime mover' is electrical, a Ward Leonard drive unit consists of a motor and generator with shafts coupled together. The prime mover, which turns at a constant speed, may be AC or DC powered. The generator is a DC generator, with field windings and armature windings. The input to the amplifier is applied to the field windings, and ...
CC-Link Industrial Networks – Supported by the CLPA; CIP (Common Industrial Protocol) – can be treated as application layer common to DeviceNet, CompoNet, ControlNet and EtherNet/IP; ControlNet – an implementation of CIP, originally by Allen-Bradley; DeviceNet – an implementation of CIP, originally by Allen-Bradley
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
With the increasing speed of today's processors, many DCS products have a full line of PLC-like subsystems that weren't offered when they were initially developed. In 1993, with the release of IEC-1131, later to become IEC-61131-3 , the industry moved towards increased code standardization with reusable, hardware-independent control software.
The Common Industrial Protocol (CIP) is an industrial protocol for industrial automation applications. It is supported by ODVA.. Previously known as Control and Information Protocol, [1] CIP encompasses a comprehensive suite of messages and services for the collection of manufacturing automation applications – control, safety, synchronization, motion, configuration and information.
A vector inversion generator (VIG) is an electric pulse compression and voltage multiplication device, allowing shaping a slower, lower voltage pulse to a narrower, higher-voltage one. VIGs are used in military technology, e.g. some directed-energy weapons , as a secondary stage of another pulsed power source, commonly an explosive-driven ...
A variable speed motor drive is a system that includes a motor that is continuously variable in speed. If the motor is generating electrical energy rather than using it, the motor drive could be called a generator drive but is often still referred to as a motor drive.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. [ 1 ] [ 2 ] [ 3 ] These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external).
