FU2-37 [Load Inertia] must be set at the correctvalue to make this function operate correctly.FU2-22 [Speed Search Select]Setting Range4 th bit 3 rd bit 2 nd bit 1 st bitDescription0 0 0 0 Speed search function does not work0 0 0 1 Speed search during Accelerating0 0 1 0Speed search during a Fault Resetrestarting (FU2-21) and Autorestarting (FU2-26)0 1 0 0Speed search during Instant PowerFailure restarting.1 0 0 0Speed search during Power ONstarting (FU2-20)When FU2-22 is set to ‘1111’, Speed Search works for allconditions.FU2-22 [Speed Search Selection] selects the speedsearch function.FU2-23 [Current Limit Level] is the current that theinverter limits its current rise during speed searching.(The set value is the percentage of FU2-33 [Rated MotorCurrent])FU2-24 [P Gain] is the proportional gain used for speedsearch. Set this value according to load inertia set inFU2-37.FU2-25 [I Gain] is the Integral gain used for speedsearch. Set this value according to load inertia set inFU2-37.Output FrequencyOutput VoltageRelated Functions:[Speed Search Operation]FU2-26: Number of Auto Restart AttemptFU2-27: Delay Time Before Auto RestartFU2►Retry number26 026Factory Default: 0 0FU2►Retry delay27 1.0 secTimeTimeTimeFU2-20 [Power ON Start]FU2-21 [Restart after Fault Reset]FU2-26 ~ FU2-27 [Auto Restart]FU2-30 ~ FU2-37 [Motor Parameters]This function is used to allow the inverter to reset itselffor a selected number of times after a fault has occurred.The inverter can restart itself automatically when a faultoccurs. To use the speed search function during autorestarting set FU2-22 to ‘xx1x’. See FU2-22 ~ FU2-25.When an under voltage (LV) fault, inverter disable (BX)2701.0Factory Default: 1.0 sec 1.0103
