Users should select torque boost based on the
load, eg, larger load requires larger torque boost,
however, if the torque boost is too large, the motor
will run at over-excitation, which will cause
increased output current and motor heat-up, thus
degrading the efficiency.
When torque boost is set to 0.0%, the inverter is
automatic torque boost.
Torque boost cut-off threshold: Below this
frequency threshold, the torque boost is valid,
exceeding this threshold invalidates torque boost.

point 1 of motor 1
When P04.00 =1 (multi-point V/F curve), users
can set V/F curve via P04.03
–P04.08.
V/F curve is usually set according to the
characteristics of motor load.
Note:
V1<V2<V3, f1<f2<f3. If low-frequency
voltage is set too high, motor overheat or
burnt-down may occur, and overcurrent stall or
overcurrent protection may occur to the inverter.
