A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface.ariable-frequency drives are also categorized by the following load torque and power characteristics: 1  Variable torque, such as in centrifugal fan, pump, and blower applications. 2  Constant torque, such as in conveyor and positive-displacement pump applications.
data transfer rate (DTR) Speed at which data can be moved between two devices, such as from a disk drive to a computer's main memory. Modern DVD drives can transfer data at rate of 1.2 gigabytes per second (GB/sec). Between modems, DTR is measured in bits per second (bps), and between a computer and a printer in characters per second (cps).
