Industry:Automation
The speed minimum and maximum at which a motor must operate under constant or variable torque load conditions. A 50:1 speed range for a motor with top speed 1800 rpm means the motor must operate as low as 36 rpm and still remain within regulation specification. Controllers are capable of wider controllable speed ranges than motors because there is no thermal limitation; only electrical. Controllable speed range of a motor is limited by the ability to deliver 100% torque below base speed without additional cooling.
Industry:Automation
1) The time-shared scanning of a number of data lines into a single channel. Only one data line is enabled at any time. 2) The incorporation of 2 or more signals into a single wave from which the individual signals can be recovered.
Industry:Automation
A series of stations (nodes) connected by some type of communication medium. A network may be made up of a single link or multiple links.
Industry:Automation
Program instructions that perform logic functions similar to that of relay logic.
Industry:Automation
1) A light-emitting diode and a light-detecting device sealed together in an integrated package. Because they are only coupled optically, the input circuit and output circuit are electrically isolated. 2) A device that provides coupling between 2 electrical circuits by using a light circuit to signal between the 2 electrical circuits.
Industry:Automation
A mode of addressing I/O in which each I/O module slot of an I/O chassis is addressed as an I/O group. Each I/O module slot contains a single I/O group.
Industry:Automation
Any type of physical switching contacts.
Industry:Automation
The speed of an ac induction motor’s rotating magnetic field. It is determined by the frequency applied to the stator and the number of magnetic poles present in each phase of the stator windings. Mathematically, it is expressed as: Sync Speed (rpm) = 120 x Applied Freq. (Hz) / Number of poles per phase.
Industry:Automation
1) The value of damping that provides the most rapid transient response without overshooting. 2) Operation between underdamping and overdamping.
