Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
Using armature voltage as the velocity feedback signal to an electronic speed regulator. This voltage is approximately directly proportional to motor velocity, assuming a constant motor field and ignoring IR drop. Armature-voltage feedback is used where the expense of a tachometer-generator for velocity feedback is not justified and a regulation accuracy of 2–5% is adequate.
Industry:Automation
A logical structure that keeps track of items waiting for processing whenever the system is unable to process each item immediately. It controls the order in which the waiting items are ultimately processed.
Industry:Automation
The process of one intelligent device accessing the memory of another, bypassing the other processor’s general registers.
Industry:Automation
Transaction field. A 16-bit field that indicates which message transaction is taking place.
Industry:Automation
1) In a linear arrangement of parallel (bus) connections, a physical configuration such that each device is connected to the bus at the end of a drop-line that is connected to a tap at the junction of two trunk-line segments. 2) Contrasted with a daisy-chain configuration or star configuration
Industry:Automation
A quantity or condition that is varied (by the controller) as a function of the actuating error signal so as to change the value of the controlled variable. A quantity or condition that the controller applies to the controlled system.
