    What to do if Lenze DC Drives show a short-circuit or overload?
    • J
      Jonathan ShahAug 25, 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.

    How to fix communication error on Lenze ESMD371L4TXA?
    • C
      Christopher LindseySep 1, 2025
      If the Lenze Inverter reports a communication error, it could be due to the serial timer timing out. In this case, check the serial link connections.

    What causes undervoltage on DC bus in Lenze ESMD371L4TXA Inverter?
    • M
      Michael ShortSep 2, 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 Inverter stop with inhibited outputs?
    • W
      williamsjerrySep 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?
    • N
      Nicholas ClarkeSep 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 ESMD371L4TXA Inverter output frequency 0 Hz?
    • S
      Sandra CameronSep 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 Inverter buttons not working?
    • C
      Christopher DelacruzSep 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 Inverter?
    • B
      Brad WrightSep 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 Inverter?
    • T
      Todd MillerSep 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 ESMD371L4TXA Inverter?
    • F
      fjordanSep 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.
