What does E.UVT mean?

This function stops the inverter output if the power supply voltage drops below 150V (for 200V class inverters) or approximately 300V (for 400V class inverters). This prevents improper control circuit operation, reduced motor torque, or increased heat generation. It also activates if a jumper or DC reactor is not connected across terminals P/+-P1.
