8.4 TroubleshootingWhen problems occur in the servo system, they must first be located and properly identified.Table 8.1 lists potential faults on the connection box, their possible causes and actions for correcting the faults.Contact Danfoss Service if it is not possible to correct the fault.Fault/Fault Code on 7-segment DisplayPossible Cause Possible SolutionLED "CAN" is lit red constantly CAN error. • Check cabling• Check terminating resistorsLED "CAN" is off No CAN messages on the bus. • Check cabling• Check masterLED "RUN/Err" is lit redconstantlyActive connection box error. See error and warning codes below.LED "UZK" is off althoughDC 300 V power supply isconnected.• Cable connected incorrectly.• 300 V DC power supply voltage notpresent.• Connection box not switched on.• Check cabling• Check DC 300 V power supply• Switch connection box on via a command from themaster or by configuring parameter autoSwitchOnError code 3100 (hex) Input voltage (UDC) above absolutemaximum.Check stability of 300 V DC power supplyError code 3101 (hex) Input voltage (UDC below absoluteminimum.Check stability of 300 V DC power supplyError code 3102 (hex) Input voltage (UDC) below intermediatevoltage (UZK) during power up.• Check stability of 300 V DC power supply• Ensure servomotors are not active during power up sopower feedback cannot occur• Ensure no power supply is connected on the outputsideError code 3110 (hex) 24 V power supply loss. • Check cabling• Check 24 V power supplyError code 3111 (hex) 24 V power supply timeout during initiali-sation.• Check cabling• Check 24 V power supply ramp-up timeError code 3118 (hex) 5 V CAN power supply loss. • Check cabling• Contact Danfoss Service to check the 5 V internalpower supplyError code 3119 (hex) 5 V CAN power supply timeout duringinitialisation.• Check cabling• Contact Danfoss Service to check the 5 V internalpower supply ramp-up timeWarning code 3180 (hex) Switch on, nominal UDC range:Input voltage above maximum.Check power supply rangeWarning code 3181 (hex) Switch on, nominal UDC range:Input voltage below minimum.Check power supply rangeWarning code 3190 (hex) Switch on: 24 V power supply bad. • Check cabling• Check 24 V power supplyWarning code 3191 (hex) Switch on: 5 V CAN power supply bad. • Check cabling• Contact Danfoss Service to check the 5 V internalpower supplyError code 3200 (hex) Hazardous intermediate circuitry voltage.
