The problem could be on the power card, on the gate drive card,or the ribbon cable between the power card and gate drive card.WARNING 40, Overload of Digital Output Terminal 27Check the load connected to terminal 27 or remove short-circuit connec-tion. Check par. 5-00Digital I/O Mode and par. 5-01Terminal 27 Mode.WARNING 41, Overload of Digital Output Terminal 29Check the load connected to terminal 29 or remove short-circuit connec-tion. Check par. 5-00Digital I/O Mode and par. 5-02Terminal 29 Mode.WARNING 42, Overload of Digital Output on X30/6 or Overloadof Digital Output on X30/7For X30/6, check the load connected to X30/6 or remove short-circuitconnection. Check par. 5-32Term X30/6 Digi Out (MCB 101).For X30/7, check the load connected to X30/7 or remove short-circuitconnection. Check par. 5-33Term X30/7 Digi Out (MCB 101).ALARM 46, Power card supplyThe supply on the power card is out of range.There are three power supplies generated by the switch mode powersupply (SMPS) on the power card: 24 V, 5V, +/- 18V. When powered with24 VDC with the MCB 107 option, only the 24 V and 5 V supplies aremonitored. When powered with three phase mains voltage, all three sup-plied are monitored.WARNING 47, 24 V supply lowThe 24 VDC is measured on the control card. The external 24 VDC backuppower supply may be overloaded, otherwise contact your Danfoss sup-plier.WARNING 48, 1.8 V supply lowThe 1.8 Volt DC supply used on the control card is outside of allowablelimits. The power supply is measured on the control card.WARNING 49, Speed limitThe speed is not within the specified range in par. 4-11Motor Speed LowLimit [RPM] and par. 4-13Motor Speed High Limit [RPM].ALARM 50, AMA calibration failedContact your Danfoss supplier.ALARM 51, AMA check Unom and InomThe setting of motor voltage, motor current, and motor power is pre-sumably wrong. Check the settings.ALARM 52, AMA low InomThe motor current is too low. Check the settings.ALARM 53, AMA motor too bigThe motor is too big for the AMA to be carried out.ALARM 54, AMA motor too smallThe motor is too big for the AMA to be carried out.ALARM 55, AMA parameter out of rangeThe parameter values found from the motor are outside acceptablerange.ALARM 56, AMA interrupted by userThe AMA has been interrupted by the user.ALARM 57, AMA timeoutTry to start the AMA again a number of times, until the AMA is carriedout. Please note that repeated runs may heat the motor to a level wherethe resistance Rs and Rr are increased. In most cases, however, this isnot critical.ALARM 58, AMA internal faultContact your Danfoss supplier.WARNING 59, Current limitThe current is higher than the value in par. 4-18,Current Limit.WARNING 60, External interlockExternal interlock has been activated. To resume normal operation, apply24 VDC to the terminal programmed for external interlock and reset thefrequency converter (via serial communication, digital I/O, or by pressingreset button on keypad).WARNING 61, Tracking errorAn error has been detected between calculated motor speed and speedmeasurement from feedback device. The function for Warning/Alarm/Disable is set in par 4-30,Motor Feedback Loss Function, error setting inpar 4-31,Motor Feedback Speed Error, and the allowed error time in par4-32,Motor Feedback Loss Timeout. During a commissioning procedurethe function may be effective.WARNING 62, Output frequency at maximum limitThe output frequency is higher than the value set in par. 4-19Max OutputFrequencyWARNING 64, Voltage limitThe load and speed combination demands a motor voltage higher thanthe actual DC link voltage.VLT AQUA High Power Operation Instructions 7 TroubleshootingMG.20.P3.02 - VLT® is a registered Danfoss trademark 1897
