adjust f through the frequency reference
channel set by
P00.06 to change the curve
characteristic, or adjust V through the voltage
reference channel set by
P04.27 to change the
curve characteristics.
Note: The V

in the figure below corresponds
to rated motor voltage, and
f

Output frequency
P04.01 Torque boost of
motor 1
In order to compensate for low-frequency
torque characteristics, users can make some
boost compensation to the output voltage.
P04.01 is relative to the max. output voltage V
b.
P04.02 defines the percentage of cut-off
frequency of manual torque boost to the rated
motor frequency f
b.
Torque boost can improve
the low-frequency torque characteristics of
V/F.
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 will nullify torque
boost.
