· DC injection Braking Time at Start (n070)
DC injection braking time at start can be set in increments of 0.1 sec-
ond. When parameter n070 is set to "0", DC injection braking at start-
ing is disabled.
Energy Saving Control
To enable energy saving control, set energy saving selection (n096, Energy
Sav Sel) to "1".

Since the parameters used in the energy saving control mode have been
preset at the factory to the optimum values, it is not necessary to adjust
them under normal operation. If your motor characteristics differ greatly
from those of standard induction motors, refer to the following descrip-
tion to adjust the parameters.
Energy Saving Control Mode
· Energy Saving Gain K2 (n097, Energy Save Gain)
Use this energy saving gain when running in the energy saving control
mode to calculate the voltage at which motor efficiency will be greatest,
and set it as the output voltage reference. This value is preset at the fac-
tory to the standard induction motor value prior to shipment. As the
energy saving gain increases, output voltage decreases.
· Energy Saving Voltage Lower Limit ( n098, EngSavVLLmt@60Hz;
Sets the output voltage lower limit. If the voltage reference value calcu-
lated in the energy saving mode is smaller than the specified lower
