Activating the energy-saving function (P770)

The energy-saving function can be activated for the following operating modes: VFC / VFC & FLYING START / V/f CHARACTERISTIC. During no-load operation, the power consumption of the inverter can be reduced by up to 70%.

Energy can be saved when operating pumps, fans, conveyor belts, etc. In this procedure, the magnetization of the asynchronous motor is controlled depending on the load by adapting the voltage-frequency ratio; the motor is undermagnetized.
