P3-03 ~ P3-08 six parameters define multi-segment V / F curve.
Multi-point V / F curve according to the motor load characteristics to set, it should be
noted that the relationship between the three voltage points and frequency points must
meet: V1 <V2 <V3, F1 <F2 <F3. Figure 6-6 for the multi-point VF curve set diagram.
Low voltage setting at high frequencies may cause the motor to overheat or burn, and the
frequency converter may over-current stall or over current protection.
