METHOD FOR OPERATING AN ELECTRIFIED DRIVE TRAIN FOR A WORKING MACHINE, ELECTRIFIED DRIVE TRAIN FOR A WORKING MACHINE AND WORKING MACHINE

A method for operating an electrified drive train including a drive motor, inverter, and accelerator pedal. The drive motor provides a motor speed and torque according to a position of the accelerator pedal. The inverter detects a motor mode when a motor torque greater than a threshold motor torque is provided. The inverter detects a generator mode when a generator torque greater than a threshold generator torque is provided. The inverter detects a torque-free state of the drive motor when the generator torque is less than the threshold generator torque and the motor torque is less than the threshold motor torque. Each position of the accelerator pedal is assigned a respective maximum motor speed, and a motor fault is detected when a motor speed above an assigned speed is detected and, at the same time, a motor mode of the drive motor is detected.
