    Why Lenze DC Drives show earth fault?
    • J
      jacqueline60Aug 25, 2025
      An earth fault in Lenze DC Drives can occur if a motor phase is grounded, so you should check the motor and motor cable. It can also be due to excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current.

    What causes motor overload on Lenze ESMD751L4TXA?
    • J
      joy57Aug 30, 2025
      If the Lenze Inverter displays a motor overload (I2t overload), it means the motor is thermally overloaded. This can be due to: * Impermissible continuous current. * Frequent or excessively long acceleration processes. To resolve this: * Check the controller selection. * Check the setting of c20.
