Note: While selecting contactor, make sure its coil voltage range (230V), Frequency (50) and which type of power supply required. A basic VFD system generally consists of an AC motor, a controller, and an operator interface. The supply voltage applied to the rectifier is a three-phase alternating voltage or a single-phase AC voltage with a frequency of 50 Hz or 60 Hz. motor will be stopped. Vfd is a short form of variable frequency drive or variable voltage variable frequency drive. Terminals are -24V, GND, DCOM,DI1, DI2,D13,DI4. A variable frequency drive controls the speed, torque, and direction of an AC induction motor. CTRL + SPACE for auto-complete. A wiring diagram is a simplified standard photographic depiction of an electric circuit. VFD is shorted for Variable Frequency Drive (also known as AC Drives and Inverters) -- that's used to make an AC motor working in variable speed (among other parameters).This is definition used in all topical discussion on this paper. In a single-phase motor speed control, the thyristor controls power in the circuit by changing the _____ angle of the AC sine wave that drives the motor. Other names of VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive.
