Manual energy saving gain (11-12)
(1) When manual energy savings is enabled, output voltage of inverter will be determined by
parameter 11-12, output voltage is percentage gain times the V/F voltage.
(2) Manual energy saving control uses the voltage recovery time (07-23) to change the output
voltage.
Manual energy saving frequency (11-18)
Setting parameter 11-18 manual energy savings frequency to 0.0 Hz disables the manual energy
savings frequency activation function. Refer to figure 4.3.88

OV Prevention Level
Range
230V :【200~400】V
400V :【400~800】V
11- 17
Acceleration/Deceleration Gain
Range
【0.1~10.0】
Parameter setting：
(1) If “OV” alarm still happened when 11-40=3, please increase the value of 11-17 in 0.1 unit.
(2) If the setting value of 11-17 is not suitable, the ripple of speed and current will be higher.
(11-14 is the target voltage of over-voltage prevention mode 3, it’s the voltage inhibition level.)
