If F0.15=0，V/F curve bears constant torque curve characteristic；as curve 0
in Fig.6-5a .
If F0.15=1，V/F curve bears 2.0 order power degressive torque characteristic；as
curve 3 in Fig.6-5a .
If F0.15=2，V/F curve bears 1.7 order power degressive torque characteristic；as
curve 2 in Fig.6-5a .
If F0.15=3，V/F curve bears 1.2 order power degressive torque characteristic；as
curve 1 in Fig.6-5a .
The user can choose 1, 2, 3 V/F curve run mode according to load
characteristic to reach better energy save result while the inverter is driving
degressive torque load such as blower and water pump etc..
If F0.15=4, you can set V/F curve yourself by setting F2.37-F2.44
parameters.
As shown in Fig.6-5b, by setting three inflexion point (V1,F1), (V2,F2),
(V3,F3), you can define V/F curve arbitrarily to apply to special load.

F0.16 G/P type setting Range: 0, 1 0
0: G type
1: P type
6.2 Start, stop, braking function parameter group: F1
F1.00 Start run mode Range: 0, 1, 2 0
0: start from starting frequency. The inverter start according to F1.01
starting frequency and F1.02 starting frequency holding time.
1: first brake then start from starting freq. First brake according to DC
braking voltage and time (F1.03, F1.04)，then start at starting frequency.
2: Start after inspecting speed. Initial tracking frequency determined by
F2.30.
