4.1 SERVOPACKs with Analog Voltage/Pulse Train References4.1.5 List of Warnings4-384.1.5 List of WarningsThe list of warnings gives the warning name, warning meaning, and warning code output inorder of the warning numbers.WarningNumber Warning Name MeaningWarning CodeOutputALO1 ALO2 ALO3A.900 Position DeviationOverflowThe position deviation exceeded the parametersettings (Pn520 × Pn51E/100). H H HA.901Position DeviationOverflow Alarm atServo ONThe position deviation exceeded the parametersettings (Pn526 × Pn528/100) when the servo wasturned ON.H H HA.910 OverloadThis warning occurs before an overload alarm(A.710 or A.720) occurs. If the warning is ignoredand operation is continued, an alarm may occur.L H HA.911 VibrationAbnormal vibration was detected during motoroperation. The detection level is the same asA.520. Set whether to output an alarm or a warn-ing by setting Pn310 (Vibration Detection Selec-tions).L H HA.912Internal TemperatureWarning 1 (ControlBoard TemperatureError)The surrounding temperature of the control PCB isabnormal. H L HA.913Internal TemperatureWarning 2 (PowerBoard TemperatureError)The surrounding temperature of the power PCB isabnormal. H L HA.920 Regenerative OverloadThis warning occurs before an A.320 alarm(Regenerative Overload) occurs. If the warning isignored and operation is continued, an alarm mayoccur.H L HA.921 Dynamic Brake Over-loadThis warning occurs before an A.731 alarm(Dynamic Brake Overload) occurs. If the warning isignored and operation is continued, an alarm mayoccur.H L HA.923 SERVOPACK Built-inFan Stopped The fan inside the SERVOPACK stopped. H L HA.930 Absolute Encoder Bat-tery ErrorThis warning occurs when the voltage of absoluteencoder’s battery is low. L L HA.941 Change of ParametersRequires RestartParameters have been changed that require thepower supply to be turned OFF and ON again. H H LA.942Speed Ripple Com-pensation InformationDisagreementThe speed ripple compensation information storedin the encoder does not agree with the speed rip-ple compensation information stored in the SER-VOPACK.H H LA.971 UndervoltageThis warning occurs before an A.410 alarm(Undervoltage) occurs. If the warning is ignoredand operation is continued, an alarm may occur.L L LA.9A0 Overtravel Overtravel was detected while the servo was ON. H L LA.9b0 Preventative Mainte-nance WarningOne of the consumable parts has reached the endof its service life. H L H
