Detailed parameter description
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 will nullify torque boost.

Setting range of P04.01: 0.0%: (automatic) 0.1%–
10.0%
Setting range of P04.02: 0.0%–50.0%
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.
