over-excitation, which may cause
increased output current and motor
overheating, thus decreasing the efficiency.
When torque boost is set to 0.0%, the
inverter uses automatic torque boost.
Torque boost cut-off threshold: Below this
frequency threshold, torque boost is valid;
exceeding this threshold will invalidate
torque boost.

gain
Used to compensate for the motor rotating
speed change caused by load change in
the space voltage vector mode, and thus
improve the rigidity of the mechanical
characteristics of the motor. You need to
calculate the rated slip frequency of the
motor as follows:
△ f=f
b
-n*p/60
Of which, f
b
is the rated frequency of the
motor, corresponding to function code
P02.01. n is the rated rotating speed of the
motor, corresponding to function code
P02.02. p is the number of pole pairs of the
motor. 100.0% corresponds to the rated
slip frequency △ f of the motor.
Setting range: 0.0–200.0%

In space voltage vector control mode, the
motor, especially the large-power motor,
may experience current oscillation at
