    What to do if Lenze DC Drives show a short-circuit or overload?
    • J
      Jerry SheltonAug 23, 2025
      If the Lenze DC Drives indicate a short-circuit or overload, the cause may be a short-circuit. You should find the reason for the short-circuit and check the motor cable. It can also be caused by excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current. If the acceleration time is too short, increase the acceleration time and check the controller selection. Also, check wiring if the motor cable is defective and check the motor for internal faults. If there is frequent and long overload, check the controller selection.

    What causes undervoltage on DC bus in Lenze Inverter?
    • S
      Shawn PerezSep 1, 2025
      If the Lenze Inverter shows 'Undervoltage on DC bus', the mains voltage might be too low. Check the mains voltage to ensure it is within the required range.

    How to resolve Lenze ESMD302L4TXA stop with inhibited outputs?
    • C
      Chase MckaySep 2, 2025
      If the Lenze Inverter stops and the outputs U, V, W are inhibited, it is because there is a LOW signal at terminal 28. To solve this, set terminal 28 to HIGH.

    How to troubleshoot Dynamic braking fault on Lenze Inverter?
    • A
      Angela GutierrezSep 3, 2025
      If the Lenze Inverter is showing a Dynamic braking fault, it indicates that the dynamic braking resistors are overheating. To resolve this, increase the deceleration time.

    Why is Lenze ESMD302L4TXA Inverter output frequency 0 Hz?
    • C
      Christine SmithSep 4, 2025
      If the Lenze Inverter's output frequency is 0 Hz and the outputs U, V, W are inhibited, it could be due to: * Setpoint = 0 Hz (C31 = 0): In this case, you need to perform a setpoint selection. * Quick stop activated through digital input or serial link: Deactivate the Quick stop.

    Why are Lenze ESMD302L4TXA Inverter buttons not working?
    • H
      Heather BrooksSep 4, 2025
      If the Lenze Inverter indicates that the remote keypad is active, the buttons on the front of the controller are disabled. This is normal operation when the remote keypad is in use.

    What to do for Controller overtemperature on Lenze ESMD302L4TXA Inverter?
    • C
      Caitlin SimpsonSep 5, 2025
      If the Lenze Inverter displays 'Controller overtemperature', it means the controller is too hot inside. To resolve this, reduce the controller load and improve cooling.

    What does current limit reached mean on Lenze ESMD302L4TXA?
    • S
      Steven DaySep 6, 2025
      If the Lenze Inverter shows 'Current limit reached', it indicates a controllable overload. This is managed automatically, as described in C22.

    How to fix No access to code on Lenze Inverter?
    • P
      perezblakeSep 7, 2025
      If the Lenze Inverter displays 'No access to code', it means that changes can only be made when the controller is in OFF or 1nh. To proceed, set terminal 28 to LOW or inhibit by serial link.
