Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The time between the end of a frame transmitted by one station to the start of the next frame transmitted by another station, as referenced by the signals on the bus. For example, from the last bit of an end flag to the first bit of a start flag.
Industry:Automation
A technique for generating a dc voltage level from a higher constant dc voltage. The constant input voltage is chopped to produce pulses at a constant period and constant amplitude. Modulating the pulse width (duration) controls the average voltage of the output.
Industry:Automation
1) To embed a subroutine or block of data into a larger routine or block of data. 2) On a ladder logic rung, to have one branch begin or end within another branch.
Industry:Automation
The current required by a motor to produce torque and drive a load. The maximum safe, continuous current is stamped on the motor nameplate. This can only be exceeded for initial acceleration, and for short periods of time. Armature current is proportional to the amount of torque being produced; therefore, it rises and falls as the torque demand rises and falls.
Industry:Automation
The ratio of the non-link information transferred to the potential information transfer on the communication link.
Industry:Automation
A condition in which a motor does not rotate smoothly, but “steps” or “jerks” from one position to another during shaft revolution. Cogging is most pronounced at low speeds and can cause objectionable vibrations in the driven machine.
