Six parameters of F3-03 to F3-08 dene MS V/F curve.
The setup value of V/F curve is generally set in accordance with the load characteristics of the
motor.
Caution: V1<V2<V3 and F1<F2<F3. In case of low frequency, higher setup voltage may cause
over heat and even burning of the motor and stall over current or current protection of the
inverter.
