Publication number: 20230068188Abstract: A method is provided for controlling a pump driven by a motor with the motor connected to a drive. The method can include determining a parameter value related to a fault condition, comparing the parameter value to a threshold value, and adjusting a speed control of the drive based on the comparison of the determined parameter to the threshold value.Type: ApplicationFiled: November 8, 2022Publication date: March 2, 2023Inventors: Melissa Drechsel Kidd, William James Genaw, Michael Pasche, Gary T. Baase, II

Patent number: 11493034Abstract: A variable frequency drive system and a method of controlling a pump driven by a motor with the pump in fluid communication with a fluid system is provided. The method includes monitoring a pressure in the fluid system, monitoring and adjusting an operating frequency of the motor to maintain the pressure at a pressure set point, and, based on the monitored operating frequency, causing the pump to temporarily boost the pressure in the fluid system to a temporary boost set point for a first time period. The method also includes determining whether the temporarily boosted pressure in the fluid system stays above the pressure set point for a second time period and causing the pump to enter a sleep mode when the temporarily boosted pressure stays above the pressure set point through the second time period.Type: GrantFiled: November 25, 2019Date of Patent: November 8, 2022Assignee: Pentair Flow Technologies, LLCInventors: Melissa Drechsel Kidd, William James Genaw, Micheal Pasche, Gary T.
