If P00.00 set as 0(V/F control mode), then V/F type is set by P04.00. User can select appropriate V/F
curve type according to loading type. If loading is wind pump water pump etc., generally select square
V/F curve, 2.0 # power. As below diagram:

When P04.00 set as 1(MS V/F), each stage frequency and voltage can be set by above function code,
details as below diagram. The 1
st
point is 0.00Hz, output voltage is manual torque boost (P04.09)
corresponding voltage. The 5
th
point is rate frequency, output voltage is rate voltage. Other voltage is
formed by 5points linear interpolation. MS V/F is used in special application which users has output
voltage requirement, or be used in solving some frequency point with resonance phenomena.
