92Power Unit CodeThis indicates that there is aproblem either with the serialcommunication between the driveand the encoder or the value of thedata being transferred. The fullmeaning of this error must bedecoded through parameterUS.26.Error Power Unit Code. Duringthe initialization phase thepower stage was not identifiedError Power Unit Code Changed.Indicates the power unit code haschanged. This is typically experi-enced when exchanging controlcards.Error current check. Prior to everyrun the drive sends current to eachphase of the motor to verify theconnection. Afterward, the driveapplies magnetizing current andmonitors whether the motor ismagnetized or not.This error indicates the feedbackcard has been changedThis error indicates the feedbackcard has an invalid identifica-tion code.• Disconnection of the encoder while the powerto the drive is on.• Absolute position value transferred fromencoder does not match the current valueachieved through the incremental channels.• This error does not reset with the RST inputor the auto reset function. To clear thiserror go to parameter LF.26, press functionto show the value and then press enter.• Hardware failure replace the elevator drive• The unit will automatically configure itself forthe new power stage and clear the error.• The drive will keep a history of all changes forfuture reference.• To manually clear this error, go to parameterUS.27, press “function” and then “enter” andthe error should clear.• One or more motor leads is not connected.• Motor contactor is not closing or not closing intime - verify switching time of contactor• Motor contactor contacts are burnt or damaged- Inspect contactor• Motor windings are damaged. Measure motorresistance.• Drive is not able to generate acceptable currentlevels - after check everything above it theproblem could be drive related.• The unit will automatically clear the error andacknowledge the new feedback card. The unitkeeps and internal log of all changes to thefeedback board for future reference.• The card was most likely damage. Replace thefeedback card.Display Description Cause and SolutionEncoderCommunicationErrorError CurrentCheckEncoder CardChangeEncoder CardInvalidError MessagesPower Unit CodeChanged
