Schneider inverter our most common problem is that there is no appearance of power-on, the switching power supply of this series of inverter uses a UC2842 chip as a waveform generator, the damage of the chip will cause the switching power supply to be unable to operate, so that it can not be displayed normally, in addition, the abnormal operation power supply of the chip will also make the switching power supply unable to operate normally.
Schneider inverter our more common faults are mainly the damage of the drive circuit, as well as the damage of the IGBT module, the drive circuit is driven by a pair of tubes to drive the IGBT module, and this pair of tubes is also the simplest damage components, the cause of damage is often because of the damage of the IGBT module, resulting in high voltage and high current into the drive circuit, resulting in damage to the components of the drive circuit.
Schneider inverter, we often encounter the fault phenomenon of F008 (low DC voltage), because it is directly through the resistance step-down to obtain the sampling signal, so the fault F008 is mainly caused by the damage of the sampling resistor.
Schneider inverter F025, F026, F027, about the alarm of the missing input phase, the cause of the fault is because the 6SE70 series itself has the function of input phase detection, the damage of the input detection circuit will lead to the input phase loss alarm, if the cause of this fault is eliminated, the alarm signal can not be eliminated, then the fault is likely to be the damage of the CU board.
