VFDs boost productivity with the ability to gain precise control of processes. Whether it’s speed, torque, or position control (or any combination), VFDs offer the ability to fine tune and control electrically driven machines to make them more efficient for high volume, high-quality production. Controllability and tuning make machines more adaptable and compatible with changing production materials and processes. VFD also allows easy monitoring of machine production through digital and analog signals as well as serial communication. VFD often reduces energy costs when used to decrease speed or torque, particularly with centrifugal-type loads such as fans or pumps.
