Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
1) An ac adjustable-frequency drive. 2) A particular section of an ac drive. This section uses the dc voltage from a previous circuit stage (intermediate dc circuit) to produce a pulse-width-modulated or stepped ac current or voltage waveform that has characteristics similar to the desired sine-wave frequency. 3) A circuit whose output signal is the inverse of its input (a positive-going pulse is inverted to a negative-going pulse, and vise versa).
Industry:Automation
A product that can be located in a hazardous location.
Industry:Automation
In an SLC controller, the process of transferring contents of the memory module to the processor memory at power up.
Industry:Automation
Transfers that occur repeatedly at a regular specified interval, asynchronous to the program scan.
Industry:Automation
An error-checking method that adds a check or parity bit to each character in a message so the number of 1 bits, including the parity bit, in each character is odd (odd parity) or even (even parity).
Industry:Automation
The portion of memory or auxiliary storage that contains the data needed by a program.
Industry:Automation
The time required for the processor to scan all I/O modules, writing output data and reading input data. For local I/O, the I/O scan is typically in sequence with the program scan, in one overall scanning sequence. For remote I/O, the I/O scan is separate from the program scan; it is either left asynchronous to the program scan or is synchronized to the program scan by buffering input data from the I/O scan to write it into the input image table only immediately before the start of each program scan.
Industry:Automation
This type of motor mounting is used to close-couple pumps and similar applications where the mounting holes in the face are threaded to receive bolts from the pump. Normally C-face is used where a pump or similar item is to be overhung on the motor. This type of mounting is a NEMA standard design and available with or without feet.
Industry:Automation
To convert software into a different form for use in an environment different from that for which it was originally generated.
