Figure 7-4 V/F curve
You can define a curve by P3.01~P3.06, i.e. a polygonal line defined by 3
points V1, V2, V3 is Relative to the percentage of the maximum output
voltage.
Figure 7-5 User Defined V/F curve
When VFD worked in low frequency, setting torque boost
value reasonablely to counteractthe output voltage reduction, in order to
achieve sufficient output torque.
