Figure 6−TT VTF curve
P4.00 is used to set the VTF curve selection.
0: Linear VF, Applicable to the constant torque load situation.
T: Multi-point VF curve setting by user, applicable to sectional constant torque load.
F0<FT<FT<F3<f
V0≤VT≤VT≤V3≤T00%
T~6: Applicable to the variable torque loads such as fan and pump. When P4.00 is set to T~6, it
corresponds to T.T−power, T.4−power, T.6−power, T.8−power and T-power. The T-power curve is
for water supply and the T.T−power to T.8−power curves are for other liquid media loads. Proper
curve can be selected according to the actual situation.
P4.00=T~6 is valid in E5−A, E5−H−4T**G−63 series.
P4.00=T~6 is invalid in E5−H series, if power curve is needed, use multi-point VTF curve instead.
For settings, refer to the following table.
