Parameter group 77. Energy saving function

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%. Observe the following limitations:

• The energy-saving function only offers advantages in the part-load range
• No large changes in load should occur during operation

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.
