In addition, its main electrical control technology inherits the mature design of the ATV61 / 71, perfectly combining high performance with advanced functional creativity, while maintaining a friendly human-machine interface and operating mode, and excellent performance; the included DC Reactor, effectively protect the inverter from high-harmonic current and overload, and reduce harmonic interference to the power grid.

The most common failure of Schneider inverters is that there is no display when they are powered on. The switching power supply of this series of inverters uses a UC2842 chip as a waveform generator. Damage to the chip will cause the switching power supply to fail to work, which will not display properly. The abnormal working power supply will also make the switching power supply unable to work normally.
The most common faults of Schneider inverters are the damage of the drive circuit and the IGBT module. The drive circuit is driven by a pair of tubes to drive the IGBT module. This pair of tubes is also the most easily damaged component. Due to the damage of the IGBT module, high-voltage and large-current flows into the driving circuit, and the components of the driving circuit are damaged.
