    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 to do if Lenze Inverter shows short-circuit or overload?
    • W
      William AguirreAug 29, 2025
      If the Lenze Inverter experiences a short-circuit or overload, there are several potential causes: * A short-circuit itself: Investigate the cause and inspect the motor cable. * Excessive capacitive charging current: Use shorter motor cables. * Acceleration time is too short: Increase the acceleration time and check the controller selection. * Defective motor cable: Check the wiring. * Internal fault in the motor: Check the motor. * Frequent and long overload: Check controller selection.

      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.

    Why does my Lenze DC Drives show overvoltage on DC bus during deceleration?
    • R
      Ryan HansenSep 12, 2025
      If your Lenze DC Drive indicates 'Overvoltage on DC bus during deceleration (warning)', this is caused by an excessively short deceleration time (C13). The system will respond automatically, marked as OU if the overvoltage lasts for more than 1 second.

    How to fix EPM error on Lenze SMD DC Drives?
    • C
      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 DC Drives controller overtemperature?
    • J
      jonesbrianSep 18, 2025
      If your Lenze DC Drive controller is overtemperature, it means the controller is too hot inside. To fix this, reduce the controller load and improve cooling.

    What causes faulty auto-TRIP reset on Lenze SMD DC Drives?
    • T
      Timothy BaileyAug 27, 2025
      If your Lenze DC Drive displays 'Faulty auto-TRIP reset', it means there have been more than 8 errors in 10 minutes. The solution depends on the specific error.

    What does external error mean on Lenze DC Drives?
    • F
      fbryantAug 26, 2025
      If your Lenze DC Drive reports 'External error', it means the digital input “TRIP set” is active. You should remove the external error to resolve this.

    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.
