When d2-00 set to 1, these six parameters are used to define the multi-point V/F curve.
The multi-point V/F curve is set based on the motor's load characteristic. The relationship between voltages and
frequencies is: V1 < V2 < V3, F1 < F2 < F3. Diagram 6-32 shows the setting of multi-point V/F curve.
At low frequency, higher voltage may cause motor overheat or even burnt and cause frequency inverter over
current stall or over current protection.
