Variable Frequency Drive (VFD)
Variable Frequency Drive (VFD) can be used in lots of fields. Variable frequency drives are widely used to control the speed of AC motors, like conveyor systems, blower speeds, pump speeds, machine tool speeds, & other applications that require variable speed with variable torque. In some applications such as speed control for a conveyor, the variable frequency drive is installed with a remote potentiometer that personnel can adjust manually to set the speed for the conveyor. In this type of application, the personnel who use the conveyor can manually set the motor speed with the minimum & maximum frequency that is programmed into the variable frequency drive parameters. Following tables will guide you the general purpose VFD and vector VFD applications.
