Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The concept of varying the speed of a motor, either manually or automatically. The desired operating speed (set speed) is relatively constant regardless of load.
Industry:Automation
On a communication link, a station that cannot initiate communication. Only a master can initiate communication.
Industry:Automation
1) A circuit whose two sides are electrically alike and symmetrical to a common reference point, usually ground. 2) Contrasted with unbalanced circuit
Industry:Automation
A system that controls motion only to reach a given end point, but exercises no path control during the transition from one end point to the next.
Industry:Automation
A memory where data can be stored (write mode) or accessed (read mode). The write mode replaces previously stored data with current data; the read mode does not alter stored data.
Industry:Automation
Base speed is the manufacturer’s nameplate rating where the motor will develop rated power at rated load and voltage. With dc drives, it is commonly the point where full armature voltage is applied with full-rated field excitation. With ac systems, it is commonly the point where 60Hz is applied to the induction motor.
Industry:Automation
The condition at a particular time of any of numerous entities within a system. These conditions may be represented by values in a status file.
Industry:Automation
The time a device allows between operations before terminating communication on a channel.
