The FPC5010S bypass system combines the company’s GP10 drive technology and its patented Smart Bypass. According to the manufacturer, this patent-pending technology monitors drive load and speed, automatically and smoothly transferring the motor from vfd control to across the line at full speed. The Smart Bypass controller continues to monitor demand, and when requirements are decreased, transfers the motor back to drive control. It also improves harmonic distortion at full load by removing the drive from the circuit at the time when harmonic content is greatest; this reduces full-load drive harmonics by as much as 20%, says the company. An adjustable hysteresis function is built into the control algorithm to prevent rapid cycling from the drive to bypass.
