6.2 Warning Displays6.2.1 List of Warnings6-366.2 Warning DisplaysIf a warning occurs in the SERVOPACK, a warning number will be displayed on the panel dis-play. Warnings are displayed to warn you before an alarm occurs.6.2.1 List of WarningsThe list of warnings gives the warning name and warning meaning in order of the warning num-bers.If “All Axes” is given below the warning number, the warning applies to both axes. If a warningoccurs for one axis, the same warning status will occur for the other axis.WarningNumber Warning Name Meaning ResettingA.900 Position DeviationOverflowThe position deviation exceeded the percentage setwith the following formula:(Pn520 × Pn51E/100)Required.A.901Position DeviationOverflow Alarm atServo ONThe position deviation when the servo was turned ONexceeded the percentage set with the following formula:(Pn526 × Pn528/100)Required.A.910 OverloadThis warning occurs before an overload alarm (A.710 orA.720) occurs. If the warning is ignored and operation iscontinued, an alarm may occur.Required.A.90D Position DeviationBetween Axes Over-flow WarningThe position deviation between axes A and B hasexceeded the percentage set with the following equa-tion during the servo ON state.(Pn66A × Pn669/100)Required.A.911 VibrationAbnormal vibration was detected during motor opera-tion. The detection level is the same as A.520. Setwhether to output an alarm or a warning by settingPn310 (Vibration Detection Selection).Required.A.912Internal TemperatureWarning 1 (ControlBoard TemperatureError)The surrounding temperature of the control PCB isabnormal.
