INVT VFD Complete Setting in Punjabi I Variable Frequency Drive programming parameter Setting urdu
Es video men apko punjabi zaban men invt ki setting or faults k baray men batay gay.
A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively.
What is the working principle of VFD?
According to the variable frequency drive working principle, it's the electronic controller specifically designed to change the frequency of voltage supplied to the induction motor. In the 1960s, VFDs had rather small solid-state components that limited the amount of current the VFD could supply to the motor.
Where is VFD used?
VFDs are used in applications ranging from small appliances to large compressors. About 25% of the world's electrical energy is consumed by electric motors in industrial applications.
What are the types of VFD?
The main three types of VFD are VSI, CSI, and PWM.
VSI type VFDs. VSI stands for Voltage-source inverter. This is the most common type of variable frequency driver. ...
CSI type VFDs. CSI stands for current source inverter. ...
PWM type VFDs. This is an improved and modified version of VSI type VFDs.
Why VFD is used in pumps?
A variable frequency drive is used for adjusting a flow or pressure to the actual demand. It controls the frequency of the electrical power supplied to a pump or a fan. Significant power savings can be achieved when using a VFD. ... It controls the frequency of the electrical power supplied to the motor.
How do I choose a VFD?
Thus, the rule of thumb for sizing the single phase input on a three-phase drive is to use a VFD rated for 2 times the FLA of the motor. For example if your motor is a 10 HP motor with a FLA of 28 amps, then you would need to select a VFD with an amp rating of 56 amps which ends up being around 20 HP.
Which VFD is best?
I know I need a VFD, but which manufacturer is best?
Lenze AC Tech. These variable frequency drives are popular for their NEMA 4X indoor and outdoor vfd options. ...
Fuji Electric. Known for their high-quality FRENIC series of variable frequency drives. ...
Delta Industrial Automation. Delta drives are available from ¼ to 475hp in 115 to 575V. ...
GE Industrial Solutions.
Can I put a VFD on any motor?
Output voltages are available for VFDs to match almost any existing motor voltage. However, very few, if any, VFDs have a direct 13,800-volt output for very high-voltage motors. For these cases, using a step-up transformer on the output of the VFD is often necessary to match the motor voltage.
