Setting Range: 0.0 to 400.0Hz

Factory Default: 0.0Hz

After the multi-function contact input for energy-saving operation closes (H1-__, setting: “63”), the

output voltage is decreased when the output frequency reaches the energy-saving starting frequency.

This feature is only enable by multi-function contact input.

This parameter is used to select if Automatic Energy Saving Mode is to be on or off. A multi-function

contact input is not required to activate Automatic Energy Saving Mode. This mode of operation auto-

matically searches for the optimum motor voltage required to save energy. This function is separate

and not to be confused with parameters B8-01 and B8-02. The energy saving mode that utilizes B8-01

and B8-02 requires a multi-function input to be activated for operation. This Automatic Energy Sav-

ing Mode selection does not require a multi-function input to activate operation.

Setting Range: 0 to 10.0

Factory Default: 0.7

The output voltage during energy-saving operation is the product of the normal V/f settings (El-03 to

E1-10) and the energy saving gain. The output voltage decreases and recovers according to the Energy-

Saving Control Time Constant B8-05. As the energy saving gain increases, the output voltage

increases also.

Note: When the control mode A1-02=3, the default factory setting becomes 1.0

Setting Range: 0.00 to 10.00

Factory Default: 0.50

Parameter B8-05 sets the response time for the Automatic Energy Saving function.

Decreasing the Energy Control Time-Constant, will cause the response to become quicker; however,

instability may occur if this is decreased too much.

Note: When control mode A1-02=3, the default factory setting becomes 0.01.
