Adjust this parameter can prevent motor oscillation
when drive using V/F control.

This group of parameters define the V/F setting modes
of SV100 so as to satisfy the requirements of different
loads. 3 preset curves and one user-defined curve can
be selected according to the setting of b1.00.
If b1.00 is set to 1, a 2-order curve is selected, as shown
in Fig. 6-35 as curve 1;
If b1.00 is set to 2, a 1.7-order curve is selected, as
shown in Fig. 6-35 as curve 2;
If b1.00 is set to 3, a 1.2-order curve is selected, as
shown in Fig. 6-35 as curve 3;
The above curves are suitable for the variable-torque
loads such as fan & pumps. You can select the curves
according to the actual load so as to achieve best
energy-saving effects.
Fig.6-35 Torque-reducing curve
If b1.00 is set to 0, you can define V/F curve via
b1.01~b1.06, as shown in Fig. 6-36. The V/F curve can
be defined by connecting 3 points of (V1,F1), (V2,F2)
and (V3, F3), to adapt to special load characteristics.
Default V/F curve set by factory is a direct line as show
in Fig. 6-35 as curve 0.

b1.07 Cut-off point used
for manual torque boost
b1.07 defines the ratio of the cut-off frequency used for
manual torque boost to the basic operating frequency
(defined by A0.12), as shown in Fig. 6-36 as Fz.This
cut-off frequency adapts to any V/F curve defined by
b1.00.
