To obtain the best energy-saving effect, user can select V/F curve 1, 2, 3 for fan, pump load.

V/F curve
Fig. 4-8 User-defined V/F curve
When P0.22 = 4, you can define V/F curve via modifying (V1, F1), (V2, F2), (V3, F3) to satisfy the special load require-
ment, as shown in Fig.4-8. Torque boost is suitable for user-defined V/F curve. In Fig.4-8.

P1.00
Time constant of analog filter
Range: 0.01~30.00s
0.20s
The inverters filter time for sample value when set the frequency by analog channel. If the wiring is too long or noise is too
serious, increase this parameter to improve the frequency stability. The longer the filter time, the stronger the noise immun-
ity ability. However, the reponse will be slower.
