Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
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.
Industry:Automation
Keys on a keyboard labeled F1, F2, F3, etc. The function of each of these keys is defined by software and a key may have a different function for each menu display.
Industry:Automation
Usually computerized programs to manage flow of materials and labor for manufacturing operations.
Industry:Automation
A machine with ventilating openings that permit passage of external cooling air over and around the windings of the machine (NEMA Standard).
Industry:Automation
An instruction required on the last rung of a transition file of a sequential function chart.
Industry:Automation
The process of reducing the shunt field excitation on a dc motor to a level lower than its rated hot field current value. This is typically done dynamically while the motor is running under regulator control to allow motor speeds higher than the motor’s base speed. The motor’s torque capability decreases as the field is weakened, which allows constant horsepower to be delivered to the load at a given armature current level.
Industry:Automation
1) In a motor, the arrangement of laminations on a rotor or armature to provide a slight angular pattern of their slots with respect to the shaft axis. This pattern helps reduce low-speed cogging in an armature and minimize induced vibration in a rotor, as well as reduce associated noise. 2) In a split axis configuration, the difference between the positions of the two ball nuts of the split axis.
Industry:Automation
A quantity that denotes both magnitude and direction in relation to a given frame of reference. Examples of quantities that are vectors are displacement, velocity, force, and magnetic intensity.
