These six parameters are used to define the multi-point VF curve.
The multi-point VF curve is set based on the motor's load characteristic. The relationship between voltages
and frequencies is:
V1 < V2 < V3, P1 < P2 < P3
At low frequency, higher voltage may cause overheat or even burnt out of the motor and over current stall or
