HOA Keypad Display Alarm NamerUn Motor Switch during RunA command to switch motors was entered during run.SEMEMOBUS/Modbus Communication Test Mode ErrorNote: This alarm will not trigger a multi-function output terminal that is set for alarm output(H2-oo = 10).SPLSuction Pressure LossSuction Pressure LossWire-break detection for suction pressure.THo<1>Thermistor DisconnectThe thermistor used to detect motor temperature has become disconnected.TrPC IGBT Maintenance Time (90%)IGBTs have reached 90% of their expected performance life.UL3Undertorque Detection 1The current has fallen below the minimum value set for torque detection (L6-02) for longer than the allowable time(L6-03).UL4Undertorque Detection 2The current has fallen below the minimum value set for torque detection (L6-05) for longer than the allowable time(L6-06).UL6 Motor UnderloadThe load has fallen below the underload curve defined in L6-14.UvUndervoltageOne of the following conditions was true when the drive was stopped and a Run command was entered:• DC bus voltage dropped below the level specified in L2-05.• Contactor to suppress inrush current in the drive was opened.• Low voltage in the control drive input power. This alarm outputs only if L2-01 is not 0 and DC bus voltage isunder L2-05.voF Output Voltage Detection ErrorProblem detected with the voltage on the output side of the drive.WLLWater Level Loss Water Level LossWL/SP/PIAux LostSwitched to NetAnalog Water Level / Suction Pressure / Aux PI Feedback LostNetwork Water Level / Suction Pressure / Aux PI Feedback is now being used because a wire-break was detectedwith the analog signal.Water Level Analog Input Wire Break (WL Wire Break) is effective when Q4-16 is set to 1 (Alarm) or 2 (Fault).Suction Pressure Analog Input Wire Break (SP Wire Break) is effective when Q5-19 is set to 1 (Alarm) or 2 (Fault).WrUn Waiting for Run<1> Detected in models 4A0930 and 4A1200.u Operator Programming Errorsn oPE CodesAn Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to aninappropriate value.The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, does nottrigger an alarm or fault output. When an oPE appears on the operator display, press the ENTER button to view U1-18 andsee which parameter is causing the oPE.HOA Keypad Display Error NameoPE01 Drive Capacity Setting FaultDrive capacity and the value set to o2-04 do not match.oPE02 Parameter Range Setting ErrorUse U1-18 to find parameters set outside the range.oPE03 Multi-Function Input Selection ErrorA contradictory setting is assigned to multi-function contact inputs H1-01 to H1-08.oPE04 Initialization Required, Term <–> Ctrl Chgi.6 TroubleshootingYASKAWA TOEP YAIP1W 02E YASKAWA AC Drive - iQpump1000 Installation & Start-up Guide 81
