The speed dynamic response characteristics in vector control can be adjusted by setting the
proportional gain and integral time of the speed regulator.
To achieve a faster system response, increase the proportional gain and reduce the integral
time. Be aware that this may lead to system oscillation.
The recommended adjustment method is as follows:
The default setting meets the requirements of most applications. If the default setting cannot
meet the requirements (especially when the motor power is very small), the default speed
loop proportional gain may be a little large, and the motor oscillates at startup.
In this case, decrease the proportional gain rst to ensure that the system does not oscillate,
and then reduce the integral time to ensure that the system has quick response but small
overshoot.
If both F2-02 (Switchover frequency 1) and F2-05 (Switchover frequency 2) are 0, only F2-
03 and F2-04 are valid.

F2-07 Current loop KI1 (torque) 10–1000 30 - ★
They are regulation parameters for the torque axis current loop.
These parameters are used as the torque axis current regulator in vector control. The most
appropriate values of the parameters matching the motor characteristics are obtained by
means of motor auto-tuning. You need not modify them generally.

It is used to set the torque upper limit of the motor. The value 100% corresponds to the rated
output torque of the adaptable motor.
