5.4.10 ADV-50 Energy Saving Operation
5.4.10.1 Manual Energy Saving Operation
If the inverter output current is lower than the current which is set at MOT-05 (Motor Rated Curr), the
output voltage is reduced by the percentage set in ADV-51 (Energy Save). The voltage before the
energy saving operation starts will become the base value of the percentage. Manual energy saving
operation does not operate during acceleration and deceleration.

5.4.10.2 Automatic Energy Saving Operation
The inverter calculates the optimal energy saving point for the time set in ADV-52. The energy saving
point is based on the rated current and the output power of the motor. The energy saving operation is
effective for normal duty operations. It does operate when the load level is more than 80% of the rated
motor current.

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.
