PLC: Programmable Logic Controller.It is used for Controlling electromechanical system. It have built in Operating system to command the system through programming.
Vfd: Variable frequency drive.It is used for controlling speed and torque of motor by varying frequency and voltage.
PLC is a device that was invented to replace necessary sequential control by relay logic to to reduce hardware for quick modification and trouble shooting.
VFD is a device which control AC MOTOR Frequency through Inversion of AC power into DC then DC power convert it into PWM (pulse width modulation).
PLC- PROGRAMMABLE LOGIC CONTROLLER
VFD-VARIABLE FREQUENCY DRIVE
PLC: Programmable Logic Controller.
is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices .
Vfd: Variable frequency drive.
is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor
