Six parameters of F1-07 to F1-12 define the multi-point V/F curve. The
frequency point setup range is 0.00Hz to rate frequency of motor, and the
voltage setup range is 0.0% to 100%, which corresponds to 0V to rated
voltage of motor.
The setup value of multi-point V/F curve is generally set in accordance with
the load characteristics of the motor. The setting of multi-point V/F curve is
as shown in Fig.6-3.
Caution:
1) It must set as follows: F1-05<=F1-09<=F1-11. To ensure the
setup is correct, this inverter imposes restriction on the relationship
between the upper limit and the lower limit of frequency points F1-07,
F1-09 and F1-11. It must set F1-07 firstly, followed by F1-09 and
F1-11.
