Variable Frequency Drives (VFD) are commonplace in the design of mechanical systems. Where "VFD" is the most common terminology used, they are also called adjustable frequency drives, variable speed drives, and AC drives. Their primary use is to adjust the speed and/or torque in an electro-mechanical system by varying input frequency and ...

A variable frequency drive is a device that is used to control the power consumption of the motors. If we use VFD then we can decrease the amount of energy that the motor used for its operation. A variable frequency drive can vary the speed and torque of a motor and it is done by controlling the frequency of the power to the motor.

Programming a VFD is often needed to apply the device for a specific application. The entire list of adjustable parameters in a VFD is extensive, many of which will not require adjustment. Important items to review and set prior to starting the system for the first time include: ˜ Control method: scalar, vector or DTC ˜ Maximum voltage

Figure 5a. VFD liquid-to-liquid cooling system Figure 5b. VFD liquid-to-air cooling system as shown in Figure 5b. The cooled liquid then flows back to the VFD and the whole process is repeated. Approximately 90% of the heat generated by the VFD is cooled by the liquid, and 10% of the heat is still transferred to the air.

If the VFD system has bypass, there will be an overload device for the bypass circuit, but if tripped, will also prevent the VFD connect to the motor. Make sure if you have a bypass function that both the VFD and bypass mode operate the motor in the same direction. Test the VFD without a motor to possibly isolate a problem (V/Hz).

expectancy of the VFD or damage the VF D. Figure 2 shows the effects of a power system with 5 kA PSCC on the input current of a 5 hp drive. The peak input current is around 30 A. In Figure 3 the same model drive and output load are used as in Figure 2, but the input power system is modified to provide 100 kA PSCC. Note that

When it comes to selecting a variable frequency drive for an application that needs tight speed and torque control, you want to look at a VFD that is capable of the following: Encoder feedback. When it comes to knowing what the speed of the motor is, there is no substitute to having an encoder mounted directly on the motor and providing true ...
