Multi-stage V/F curves are defined by 12 parameters from F140 to F151.
The setting value of V/F curve is set by motor load characteristic.
Note:
V1<V2<V3<V4<V5<V6，F1<F2<F3<F4<F5<F6.
As low-frequency, if the setting voltage is too high, motor
will overheat or be damaged. Inverter will be stalling or occur over-current protection.

This function can meet the needs of some special loads, for example, when the frequency outputs 300Hz and
corresponding voltage outputs 200V (supposed voltage of inverter power supply is 380V), turnover
frequency F118 should be set to 300Hz and F152 is set to
（200÷380）×100=52.6。
And F152 should be
equal to the integer value 53.
Please take care nameplate parameters of motor. If the working voltage is higher than rated voltage or the
frequency is higher than rated frequency, motor would be damaged.
