4.19 Energy saving operation and energy saving monitor

Purpose
Energy saving operation
How much energy can be saved

4.19.1 Energy saving control (Pr. 60)

Without a fine parameter setting, the inverter automatically performs energy saving control.
This inverter is optimum for fan and pump applications.

60
Energy saving control selection*
* When parameter is read using the FR-PU04, a parameter name different from an actual parameter is displayed.
Energy saving operation mode (setting "4")
⋅ When "4" is set in Pr. 60, the inverter operates in the energy saving operation mode.
⋅ In the energy saving operation mode, the inverter automatically controls the output voltage to minimize the inverter
output voltage during a constant operation.
REMARKS
⋅ For applications a large load torque is applied to or machines repeat frequent acceleration/deceleration, an energy saving effect
is not expected.
CAUTION
⋅ When the energy saving mode is selected, deceleration time may be longer than the setting value. Since overvoltage alarm
tends to occur as compared to the constant torque load characteristics, set a longer deceleration time.
⋅ The energy saving operation mode functions only under V/F control. When the advanced magnetic flux vector control, real
sensorless vector control and vector control are selected, the energy saving mode is invalid.
