故障代碼故障現象/類型故障原因解決對策
1OvercurrentShort circuit/earth fault at the output. Motor too large. Faulty output stage.Remove short-circuit. Connect smaller motor. If fault can still not be reset, contact SEW service.
2DC link voltageDC link voltage too high.Increase deceleration ramps.
3Brake chopperRegenerative power too high Braking resistor circuit interrupted Short-circuit in the braking resistor circuit Braking resistance value too high Faulty brake chopperIncrease deceleration ramps. Check connecting leads of the braking resistor. Check technical data of the braking resistor. Exchange MOVITRAC® 31C
5Regenerative overloadWith active regen. n monit. (P520/P522) and speed control (P770): faulty encoder signals wrong number of pole pairs (P324/P344) value of increments (P773) not correctCheck encoder. Check encoder connection. Set number of pole pairs correctly. Set value of increments correctly.
4Cont. overload´t utilization too high (> 125(%)).Reduce load.
6OvertemperatureThermal overload of the inverter.Reduce load and / or ensure adequate cooling.
7Phase failureWith active mains volt. monitor.(P530) Phase missing at TL. X1:1/2/3.Check mains supply.
10Direction of rotationOnly with active speed control (P770): Encoder tracks A/A and B/B are swapped in pairs. Motor rotates in opposite direction. Regen. overload (i.e. with sagging hoist) because of excessive load or BOOST setting too low (P321/P341).Check encoder connection. Exchanging two motor phases. Reduce load or increase BOOST.
11Speed detectionOnly with active speed control (P770): Faulty encoder connection. FEN31C/FPI31C option not installed.Check encoder connection. Insert correct option (FEN31C or FPI31C).
12Mot. overloadWith active n monit. (P510/P512) and speed control (P770): faulty encoder signals wrong number of pole pairs (P324/P344) value of increments (P773) not correctCheck encoder. Check encoder connection. Set number of pole pairs correctly. Set value of increments correctly.
13Starting conditionsWith active hoist function (P710/P712): Current too low during the premagnetization phase: Motor rated power selected too small in relation to the inverter rated power. Cross-section of the motor leads too small.Check startup data and carry out new startup if necessary. Check inverter-motor connection. Check cross-section of the motor leads and increase if necessary.
14Output openWith active hoist function (P710/P712): Two or all output phases interrupted. Motor rated power selected too small in relation to the inverter rated power.Check inverter-motor connection. Check startup data and carry out new startup if necessary.
17Stack overflowInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
18Stack underflowInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
19NMI trapInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
20Undefined opcodeInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
21Protected instr.Inverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
22Word op. accessInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.
23nstruct. accessInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly,
24Ext. bus accessInverter electronics faulty. Possible cause: EMC effect.The notes for EMC compliant installation must be observed. The reset for error 25 consists of several steps: 1. Factory setting (P830 = YES) 2. Re-set matched parameters 3. Carry out reset If fault occurs repeatedly, contact SEW service.

27Ext. terminalExternal fault signal has appeared at a programmable inputEliminate the cause of the fault. Reprogram the terminal, if necessary
28Fault INTERBUSFFI31C and control mode (P841) = Fieldbus: Faulty monitoring signal.Check Fieldbus connection.
32CopyingOnly when copying the parameters (P820): Break or interference in PC or FBG31C connection.Check connection between inverter and PC. Remove FBG31C keypad and plug again.
33Master-slaveConnection master-slave is interrupted. 0V5 connection (RS-485) missing Master or slave defined incorrectly in P880.Check master-slave connection. 0V5-establish connection between master and slave Set P880 correctly.
34Fieldbus timeoutNo communication between master and slave within the specified time of the response monitoring.Check communication routine of the master. Increase fieldbus timeout time (P571)/ deactivate monitoring.
35Connection Encoder-FRSEncoder connection faulty. Power supply of the encoder faulty.Check encoder connection. Check power supply of the encoder.
36Connection Master-slaveOnly with FRS and cable break master-slave (P557) = YES: Setpoint connection of slave (TL. 98-101) is disrupted. Master Speed 0 ® slave FRS CTRL is disrupted. Slave FRS CTRL input not assigned. Master Speed 0 output not assigned. No master inverter available. Encoder < 512 pulses per revolution used.Check installation. Check programming of the binary inputs and binary outputs. Check if encoder type is correct.
37FRS RAM faultInternal fault.If fault occurs repeatedly, contact SEW service.
38FRS process data faultFault on interface between inverter and FRS.If fault occurs repeatedly, contact SEW service.
39FRS parameter data faultInvalid value for FRS parameters (P55_).Check parameter settings.
41FRS lag faultPolarity of the encoder not set correctly. Acceleration ramps too short. P-gain of the positioning controller too small Speed controller not set property. Value for lag error tolerance too smallChange polarity of encoder. Increase ramps. Increase P-gain. Select new parameters for speed controller. Increase lag error tolerance (P551). Check wiring of encoder, motor and mains phases. Check if mechanical system is sluggish or whether drive hit an obstacle.
43Fault binary outputLoad on TL. X3:61 > 150 mA. Load on the other binary outputs > 50 mA Short circuit on binary output. Capacitive load on binary output.Check installation of the binary outputs.
