Energy Saving Operation
Manual Energy Saving Operation
When the inverter output current is lower than the current which is set at bA.13 (Motor Rated
Current), the output voltage is reduced by the percentage set in Ad.51 (Energy Save). The voltage
before the energy saving operation starts will become the base value of the percentage. Manual
energy saving operation will not be carried out during acceleration and deceleration.

Automatic Energy Saving Operation
The amount of energy saving can be automatically calculated based on the rated motor current
(bA.13) and the no-load current (bA.14). From the calculations, the output voltage can be adjusted.

The inverter will exit the energy saving mode, when the reference frequency is changed or
during acceleration and deceleration. The actual Acc/Dec time may take longer than the
set Acc/Dec time due to the time required to return to normal operation.
