What is the ( Plc ) ? What is the ( vfd ) ?

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 is programming device which make control operations in electrical system vfd : this is control device called drive speclized in control in motors through frequency

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
