The EMF regulator or excitation current regulator was not optimized properly, resulting in high EMF during acceleration and reporting a fault. The solution can be to perform weak field optimization and reduce the set value of P101 (rated armature voltage of the motor). Reduce P101 and try optimizing the current loop and speed loop. If it still doesn't work, then there is basically a problem with the device. The activation condition for the F004 alarm is that the voltage of the three-phase incoming power supply is about 20% lower. The three-phase voltage detection is sent from the voltage divider resistor to the operational comparison amplifier and CPU processor to determine the high and low levels of the signal and activate the alarm code. The DC speed regulator burns out the thyristor fast capacitor protector, and when powered on, it will display the F004 code and cannot be reset. The power sampling signal is open, and the F004 alarm will also be triggered when powered on. Even if the CUD1 control board is damaged, an alarm will be triggered to activate the Siemens 6RA70. Upon startup, an alarm will be triggered for F004 fault repair
