○
When motor is under V/F control mode, especially loading motor is big power motor, it can easily
cause current oscillation, lightly that motor cannot run steadily, severely that motor can result inverter
overcurrent error. At the moment it can properly set this group parameter to eliminate such problem.

Used to set the output voltage upper / lower limit in V/F separation control, and the time needed for
output voltage increase from 0 to the upper limit or from upper limit decreasing to 0.

○
In V/F control mode, when motor RPM is higher than rate RPM, motor enter into weak flux run status.
Via setting weak flux factor to change its curve, the bigger value it is , the more steeper the curve is,
and vice versa, the flux curve getting more flat. Refer to reference function code P03.27

◎
This function is used to set the light load motor state, if open the energy saving operation. If open,
when the motor in light load condition, the inverter will automatically adjust the output voltage, in order
to achieve the goal of energy saving.
