B–62755EN/01APPENDIXB. ALARM LISTAlarmNo.MeaningDescriptionRemedyAL–31AL–32Speed detection signal disconnectionmotor restraintalarm or motor is clamped.Abnormality in RAM inside theLSI used for serial data transfer.This check is made onlywhen power is turned on.Detects that motor cannot rotate at specified speedor it is detected that the motor is clamped. (but rotatesat very slow speed or has stopped).(This includes checking of speed detection signalcable.)Detects abnormality in RAM inside the LSI used forserial data transfer. This check is made only whenpower is turned on.Remove cause, then resetalarm.Remove cause, then resetalarm.AL–33Insufficient DC link sectionchargingDetects insufficient charging of direct current powersupply voltage in power circuit section when magneticcontactor in amplifier is turned on (such asopen phase and defectifve charging resistor).Remove cause, then resetalarm.AL–34Parameter data setting beyondallowable range of valuesDetects parameter data set beyond allowable rangeof values.Set correct data.AL–35Excessive gear ratio data settingDetects gear ratio data set beyond allowable rangeof values.Set correct data.AL–36 Error counter overflow Detects error counter overflow. Correct cause, then resetalarm.AL–37Speed detector parameter settingerrorDetects incorrect setting of parameter for number ofspeed detection pulses.Set correct data.AL–39Alarm for indicating failure indetecting 1–rotation signal forCs contouring controlDetects 1–rotaion signal detection failure in Cs contouringcontorl.Make 1–rotaion signal adjustment.Check cable shield status.AL–40Alarm for indicating 1–rotationsignal for Cs contouring controlnot detectedDetects that 1–rotation signal has not occurred in Cscontouring control.Make 1–rotaion signal adjustment.AL–41Alarm for indicating failure indetecting position coder 1–rotaionsignal.Detects failure in detecting position coder 1–rotationsignal.Make signal adjustment forsignal conversion circuit.Check cable shield status.AL–42Alarm for indicating positioncoder 1–rotation signal not detectedDetects that position coder 1–rotation signal has notissued.Make 1–rotation signal adjustmentfor signal conversioncircuit.AL–43Alarm for indicating disconnectionof position coder signalfor differential speed modeDetects that main spindle position coder signal usedfor differential speed mode is not connected yet (oris disconnected).Check that main spindleposition coder signal isconnected to connectorCN12.AL–46Alarm for indicating failure indetecting position coder1–rotation signal in thread cuttingoperation.Detects failure in detecting position coder 1–rotationsignasl in thread cutting operation.Make 1–rotation signal adjustmentfor signal conversioncircuit.Check cable shield status.AL–47 Position coder signal abnormalityDetects incorrect position coder signal count operation.Make signal adjustment forsignal conversion circuit.Check cable shield status.457
