    Why is my Lenze Inverter showing overvoltage on DC bus?
    • M
      Melody BarkerAug 29, 2025
      If your Lenze Inverter is experiencing an overvoltage on the DC bus, it could be due to several reasons: * The mains voltage might be too high: Verify the mains voltage. * The deceleration time might be excessively short, or the motor might be in generator mode: Increase the deceleration time or consider using a dynamic braking option. * Earth leakage on the motor side: Check the motor and motor cable, separating the motor from the controller to diagnose.

    What does EPM error mean on Lenze Inverter?
    • J
      Jamie GrantSep 6, 2025
      If the Lenze Inverter displays 'EPM error', it means the EPM is either missing or defective. To fix this, power down the system and replace the EPM.

    What causes single phase fault in Lenze DC Drives?
    • D
      David FernandezAug 28, 2025
      If your Lenze DC Drive is showing a single phase fault, it means a mains phase has been lost. Check the mains voltage.

    What to do if Lenze SMD DC Drives lose 4-20 mA reference?
    • A
      Austin JacksonSep 23, 2025
      If your Lenze DC Drive loses the 4-20 mA reference, it means the 4-20 mA signal is below 2 mA (C34 = 4). Check the signal and signal wire.

    What does external error mean on Lenze Inverter?
    • S
      Stephanie GonzalezSep 7, 2025
      If the Lenze Inverter displays 'External error', it means the digital input “TRIP set” is active. To resolve this, remove the external error.

    What to do if Lenze SMD DC Drives output frequency is 0 Hz?
    • S
      Suzanne VasquezSep 10, 2025
      If the Lenze DC Drive's output frequency is 0 Hz and the outputs U, V, W are inhibited, the setpoint might be 0 Hz. In this case, you should select a new setpoint. Alternatively, a quick stop might be activated through a digital input. To solve this, deactivate the quick stop.

      Caroline SaundersSep 14, 2025
      If your Lenze DC Drive shows 'EPM error', the EPM is either missing or defective. Power down the drive and replace the EPM.

    What to do if Lenze SMD digital inputs not uniquely assigned?
    • N
      Nathaniel MunozSep 23, 2025
      If the digital inputs are not uniquely assigned on your Lenze DC Drive, it could be because E1...E3 are assigned with the same digital signals (each signal can only be used once) or because only “UP” or “DOWN” is used (assign the missing digital signal to a second terminal).

    How to fix stop error on Lenze SMD?
    • K
      Kimberly MartinezAug 26, 2025
      If the Lenze DC Drive displays 'Stop (outputs U, V, W inhibited)', it indicates a LOW signal at terminal 28. Set terminal 28 to HIGH to resolve this.

    What causes motor overload in Lenze SMD DC Drives?
    • T
      Thomas VargasAug 26, 2025
      If your Lenze DC Drive reports 'Motor overload (I2t overload)', the motor may be thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. Check the controller selection and the setting of c20.
