故障代码 故障现象/类型 故障原因 解决对策
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.

故障代码 故障现象/类型 故障原因 解决对策
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
