10910.2 Alarm Causes & TroubleshootingAlarmcodeAlarm Information Alarm Cause TroubleshootingFFF.F/800.0 No motor configured There is no motor type set in servodriver Set the motor type in d4.01.000.1 Internal Internal problem Please contact manufacturer000.2 Encoder ABZ The ABZ signal cable isdisconnected. Check the cable.000.4 Encoder UVW The UVW signal cable isdisconnected. Check the cable.000.8Encoder Counting Interferences are suppressed.Encoder cable problemCheck encoder cable.Remove interference(Such asconnect the motor cable to SHIELDterminal etc.)000.6Encoder Error ABZ and UVW signals of theencoders incur errorsimultaneously.Check the cable.001.0 Over Temperature The driver temperature exceeds83°C.Check whether the selected driverhas enough power.002.0Over Voltage The bus voltage of the driverexceeds the allowable range.Check the input voltage,ordetermine whether a brakingresistor is connected.004.0Low Voltage The voltage of the driver bus isbelow the allowable range.Check the input power.Power on AC first,then power DC.Reduce deceleration.008.0Over Current The power tube in the driver isfaulty, or short circuit occurs on thephase line of the motor.Check motor wires. If the motorworks properly, it can be judged thatfaults occur on the power tube inthe driver.010.0 Chop Resistor The actual power of brake resistoris larger than rated power Change brake resistor.020.0Following Error Control loop parameters settingproblem.Overload or block.Encoder signal problem.Set VFF (d2.08) as 100%,increasekpp(d2.07) and kvp(d2.01).Choose bigger power motor or checkwhether the load is blocked.Check the encoder cable.040.0 Logic Voltage The logic voltage is lower than 18V. Check the logic power supply 24V.080.0IIt Error Control loop parameters settingproblem.Overload or block.Increase kvp(d2.01).Choose bigger power motor or checkwhether the load is blocked.100.0Over Frequency The input pulse frequency exceedsthe allowable maximum value.Check the input pulse frequency andthe maximum permissible value ofthe frequency.(d3.38)。200.0 STO Error STO Error Check the wiring according to
