  • Page 69: About Typical Vfd Motor Drive Control

    An adjustable-speed drive is used to control the motor speed and torque by varying motor input frequency and voltage. A variable-frequency drive (VFD) is used in KVAL machinery to accu- rately drive motors for machining or moving product through the machine. The figure below shows a block diagram of a typical motor drive circuit.
