Parameter details
11.6 F04 Group: V/F Control
F04.0x Group: V/F control
V/F pressure frequency curve
F04.00: VF curve selection

VF curve selection
STOP
0: straight line VF curve
1-9: respectively, the torque curve of the power of 1.1-1.9 VF
10: square VF curve
11: Custom VF curve
Note:
F04.00 = 11 [VF curve selection = custom VF curve], set by F04.0x.
The straight line and the torque reduction curve are as follows. The torque reduction VF curve is valid above 0.3 times the rated motor frequency.
Torque boost
F04.01: Torque boost

Torque boost
RUN
0.0: Automatic torque boost to compensate for losses on the stator resistance.
Other values: fixed torque boost
Note:
When F04.01 = 0.0 [torque boost = automatic torque boost], the accurate stator resistance value is obtained by F02.07=3 self-learning, but the
motor output is in the best state.
The schematic diagram of the fixed torque boost under the V/F curve line and curve is as follows.
