Power Factor threshold is set which is used for dry run condition detection Normally you dont need to change the default value of 0 35 set for this p 0 Min PwrFctr parameter But in some rare cases it might need modification especially if the pump regime allows continuous operation at speed or load substantially smaller than the nominal ones In such cases faulty activation of the dry run protection may occur To avoid it you may need to slightly decrease the p 0 setting To help figure out the meaning of this Minimal Power Factor threshold here is a brief description of the principle on which the dry run protection implementation is based IUM SPCS_H Rev 00_ May 2015 docx 38 46 Copyright ELECTROINVENT Q electrolnye Al Induction motors are notorious for their poor power factor in case of idle running or when driving small loads The power factor grows up when the motor load increases and reaches values of about 0 80 or even 0 90 and more at nominal load and nominal speed depending on motor specifications So knowing the power factor value the dry run condition with respective power factor of the order of 0 20 is easily distinguished from the full load condition with power factor around 0 80 or more But if the drive is operated at speed load much smaller than the rated ones the power factor at this smaller load may occasionally drop below the default value of 0 35 so some decrease of p 0
