| 01 | Over-current | • Short circuit on output • Output switching • Motor too large • Defective output stage • Ramp limit (P138) switched off | • Rectify the short circuit • Only switch when output stage inhibited • Connect a smaller motor • Call SEW Service for advice if the fault still cannot be reset • Ramp limit (P138 = YES) |
| 03 | Ground fault | • Ground fault on motor • Ground fault on inverter • Ground fault in the motor lead • Over-current (see F-01) | • Replace the motor • Replace the MOVITRAC® 07 • Rectify the ground fault • See F-01 |
| 04 | Brake chopper | • Regenerative power excessive • Braking resistor circuit interrupted • Short circuit in braking resistor circuit • Excessively high braking resistance • Brake chopper defective • Ground fault | • Extend deceleration ramps • Check connecting harness for braking resistor • Rectify the short circuit • Check technical data of braking resistor • Replace the MOVITRAC® 07 • Rectify the ground fault |
| 06 | Supply system phase failure (only with three-phase inverter) | Phase fault | Check supply system lead |
| 07 | DC-link overvoltage | • DC link voltage too high • Ground fault | • Extend deceleration ramps • Check connecting harness for braking resistor • Check technical data of braking resistor • Rectify the ground fault |
| 08 | Speed monitoring | Current controller is operating at the setting limit due to: • mechanical overload • phase failure in supply system • phase failure in motor • Reduce load • Increase delay time setting P501 • Check current limitation • Extend deceleration ramps • Check supply system phases • Check motor feeder and motor Maximum speed for VFC operating mode exceeded | • Reduce load • Increase delay time setting P501 • Check current limitation • Extend deceleration ramps • Check supply system phases • Check motor feeder and motor Maximum speed for VFC operating mode exceeded • Reduce maximum speed |
| 10 | ILLOP | • Incorrect command during running of program • Incorrect conditions during running of program • Function not in inverter / not implemented | • Check program • Check program structure • Use another function |
| 11 | Overtemperature | Thermal overload of inverter | • Reduce load and/or ensure adequate cooling • If the braking resistor is integrated in the heat sink: Mount the braking resistor externally |
| 17-24 | System fault | Inverter electronics disrupted, possibly due to effect of EMC | Check ground connections and shields; improve them if necessary. Contact SEW Service for advice if this reoccurs. |
| 25 | EEPROM | Fault when accessing EEPROM | Call up default setting, perform reset and set parameters again. Contact SEW Service for advice if this reoccurs. |
| 26 | External terminal | Read in external fault signal via programmable input | Eliminate specific cause of fault; reprogram terminal if appropriate. |
| 31 | TF sensor | • Motor too hot, TF sensor has tripped • TF sensor of motor not connected or not connected properly • Connection of MOVITRAC® 07 and TF interrupted on motor | • Let motor cool down and reset fault • Check connections/links between MOVITRAC® 07 and TF |
| 32 | Index overrun | Basic programming rules violated causing internal stack overflow | Check and correct user program |
| 34 | Ramp timeout | The inverter signals F34 if you revoke the enable and the drive exceeds the rapid stop ramp time t13 by a certain time. | Extend the rapid stop ramp time |
| 37 | Watchdog timer | Fault in system software sequence | Check ground connections and shields; improve them if necessary. Contact SEW Service for advice if this reoccurs. |
| 38 | System software | System fault | Check ground connections and shields; improve them if necessary. Contact SEW Service for advice if this reoccurs. |
| 43 | RS-485 timeout | Communication between inverter and PC interrupted | Check connection between inverter and PC. |
| 44 | Unit utilization | Unit utilization (Ixt value) excessive | • Reduce power output • Extend ramps • If these points are not possible: Use a larger inverter |
| 45 | Initialization | Error during initialization | Contact SEW Service for advice. |
| 47 | System bus timeout | Fault during communication via system bus | Check system bus connection. |

| 77 | Control word | An external control has attempted to set an invalid automatic mode | • Check serial connection to external control • Check write values of external control |
| 81 | Start condition | Only in "VFC hoist" operating mode: The inverter could not inject the required amount of current into the motor during the pre-magnetization time: • Motor rated power too small in relation to inverter rated power • Motor cable cross section too small | • Check connection between inverter and motor • Check startup data and repeat startup if necessary |
| 82 | Output open | Only in "VFC hoist" operating mode: • Two or all output phases interrupted • Motor rated power too small in relation to inverter rated power | Check connection between inverter and PC. |
| 94 | EEPROM checksum | EEPROM defective | Contact SEW Service for advice. |
| 97 | Copy fault | • Parameter module disconnected during copying process • Switching off/on during copying process | Prior to acknowledging the fault: • Load the factory setting or the complete data record from the parameter module |
