If the keypad is not pressed within the time specified in 16-06 (returning time of automatic back button), the
keypad will automatically return to the mode screen.
When it is set to 0, the automatic return function is off. Press the back button to return to the previous directory.

Manual energy savings reduces the output voltage for the purpose of saving energy.
To enable manual energy savings set one of the multi-function digital input (03-00 to 03-07) to 20 and activate the
input or use parameter 11-18 to set the manual energy savings activation frequency.
When the output frequency rises above the value set in parameter 11-18 manual energy savings function is
enabled. Setting parameter 11-18 manual energy savings frequency to 0.0 Hz disables the manual energy
savings frequency activation function. Refer to figure 4.4.88 for more information.
Note: Only use manual energy savings functions in combination with light loads.
Manual energy saving gain (11-12) determines the output voltage of the inverter when manual energy savings is
enabled. Output voltage is percentage gain times the V/F voltage.
Manual energy saving control uses the voltage recovery time (07-23) to change the output voltage
