Think about all the options now available with modern variable frequency drives (VFDs). An interesting trend growing in popularity is one that ignores these features. The very nature of VFDs is to allow for flexibility in terms of operational needs and energy efficiency. A process can be optimized using VFDs to maximize production while minimizing operation costs by adjusting the motor speed, acceleration and torque. In addition, VFDs are designed to make adjustments based on the conditions of the environment. If the VFD involved in the process is showing signs of failure, alarm signals are triggered in the VFD and the drive adjusts accordingly.
