The VFD Panel (Variable Frequency drive panel) also known as VFD Control Panel are designed to control the speed of electric motor and feed pump. Adjustment of the speed of the motor is the application, which is required in all the process industries & machinery Mfg.'s. Variable Frequency drive is used as energy saving device for some of the machines to save power during no load or it is used as final control element of the closed loop control application where the speed of the motor is changed to control one parameter.
Some of the application is provided with manual speed control of the motors. These are the open loop control applications. It is also used in large machine applications.
Stable and reliable performance
Saves energy and therefore reduces energy costs
Isolated control signal provided by fibre optics between Power cell and Controller
Configurations: Standard V/f control, open and closed loop vector control, active-front end
Modular design of the power circuits for simpler maintenance routines.
The VFD can self-diagnose and record faults.
Complete fault monitor circuit for accurate fault alarm and protection.
