The following table shows the mapping of the FC102 alarmcodes and their mapping to the BACnet's fault codes.Fault codes FaultCodeVLT® HVAC Drive Alarms Fault DescriptionsCommunication Error 1 17, 34 Loss of communication with the networkOver Current 2 13, 40, 41, 42, 59 Instantaneous Output Current has exceededinverter rated or programmed valueOver Temperature 3 11, 29, 65, 69, 74, 244, 245, 247 Heat sink Temperature Limit has been reachedOver Speed Deviation 4 49, 62 Inverter has exceeded maximum or programmedlimitOver Voltage 5 5, 7, 64 DC Bus Voltage has exceeded inverter limitUnder Voltage 6 1, 6, 8 DC Bus Voltage is lower than required inverterlimitShort Circuit 7 16 Inverter Output has shorted Phase to PhaseGround Fault 8 14 Inverter Output Grounding Current hasexceeded manufacturerMotor Overload 9 10, 50-58, 222 Motor is overloadedInverter Overload 10 9 Timed over current faultOver Torque Detection 11 12 Programmed limit for torque has been exceededExternal Fault 12 142 External fault has been activated in the inverter.This is a hard fault that must be resetOperator Interface Error 13 - Inverter programming or operational interfacemalfunctionLoad Loss 14 3, 95, 229 Load on the Motor is less than programmed limitof system. An Example is a broken belt orcouplingConfiguration Error 15 70, 76, 79, 81, 82, 91 Errors exist in the programmed or operationalconfiguration of the inverterFeedback Failure 16 60, 90, 192 Required system operational feedback (signal orsensor) is not responding as expected for correctsystem operationOutput Phase Loss 17 30, 31, 32 One or more of the output phases from theinverter to the motor are openMotor Stall 18 99 Motor is operating in stall region and not able toacceleratePower Unit Error 19 4, 33, 36, 37, 46, 228, 246 Error sensed on the power section of the inverterInput Phase 20 - Input single phase or low line voltage conditionInternal Drive Failure 21 23, 27, 38, 39, 47, 48, 73, 85, 86 FC102 specific fault.Table 5.4 Mapping of Fault CodesBACnet Objects VLT® HVAC Drive Native BACnet Operating Instructions16 MG.14.C1.02 - VLT® is a registered Danfoss trademark55
