d1.10 is used for broken line V/f mode. Voltage value 100% corresponds to rated voltage
of motor. Please rationally set the values of frequency and voltage at knees on the basis of
characteristics of motor and load. Improper setting may rise output current even burn the motor. Figure

ATTENTION:
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≤V4
，
F1≤F2≤F3≤F4.At low frequency, higher voltage
may cause overheat or even burnt out of the motor and overcurrent stall or overcurrent protection of
the AC drive.
