The Altivar 680 Low Harmonic Drive is an active front end (AFE) drive that has a three-level input switching stage, which reduces common mode voltage and improves performance and efficiency. The 680 includes an efficiently designed input filter, which reduces common mode voltage prolonging motor lifetime. This filter also allows the drive system to provide near sinusoidal input current regardless of the percent input phase unbalance.

In pumping applications, the ability to mitigate harmonics while preforming efficiently at various speeds in a compact design brings flexibility. In addition to the drives low harmonic footprint, internal application functions, such as Anti-Jam, Multi-Pump Control, and Asset Protection via Pipe Fill, bring versatile, reliable solutions to the pumping industry without the need for additional components.
