. VFD(Variable Frequency drive) also know as VSD(Variable speed drive) is a motor controller device which changes the frequency and voltage of the incoming power supply to vary the speed of the AC motors. VFD controls and the startup and shutdown of the motor by controlling the acceleration and deacceleration of the motor.
Due to soft start of motor, no inrush current is drawn by the motor with the use of VFD.
Variable Frequency Drives(VFD) are used in industrial, commercial and residential building for motor and compressor controls. In commercial building VFDs are largely used in HVAC for Air handling unit(AHU) fan motor speed control in VAV systems. VFDs are also used with variable flow chilled water pumps, booster pumps and variable flow chillers. Apart from this VFDs are also used in Elevators and escalators to provided soft start and stops and avoid unwanted jerks.
Use of VFDs provide many advantages which include:
1) Soft start and stops of the motor reduces stress on motor and connected load.
2) Reduces stress increase life time and decreases the maintenance cost of motor and mechanical parts.
3) VFDs provide large energy savings where variable motor speed is required.
In this video we saw a practical VFD(Varaible Frequency drive) ATV61 from Schneider Electric. We expalined how to control VFD in Remote and Local mode and change its frequnecy from BMS or locally. We also saw how to program this VFD and configure different parameters of VFD. Then we also discussed about different Input/Ouput points of the VFD.

Very nice practical demonstration. As this VFD has text-detailed menu, it is very easier to program; without reading it's manual.

Yes, it is easier to configure this type of VFD with a detailed menu. While for other VFD with code based menus, we shall always refer to the manual.

Excellent presentation Is the duct pressure sensor connected to ddc &its op connected to vfd or we can connected pressure sensor directly to vfd & do pid tuning

Duct pressure sensor is connected to the DDC controller where we define the pressure setpoint. DDC then controls the VFD speed by using 0-10V analog output signal.
