P04.02
When P04.00=1 (multi-dot V/F curve), you can
set the V/F curve through P04.03–P04.08.
The V/F curve is generally set according to the
load characteristics of the motor.
Note: V1 < V2 < V3, f1 < f2 < f3. Too high
voltage for low frequency will cause motor
overheat or damage and cause VFD
overcurrent stall or overcurrent protection.
