0: The integral takes effect during the acceleration and deceleration process, and the respo-
nse is fast in the case of rapid acceleration, but it may cause speed overshoot;
1: Integral separation during acceleration and deceleration, rapid acceleration can effectively
reduce speed overshoot, but the response speed will be slower.
The vector control current loop PI adjustment parameter, this parameter will be automatically
obtained after the asynchronous machine is completely tuned, and generally does not need
to be modified. The integral regulator of the current loop does not use the integral time as the
dimension, but directly sets the integral gain. If the current loop PI gain is set too large, it may
cause the entire control loop to oscillate. Therefore, when the current oscillation or torque
fluctuation is large, the PI proportional gain or integral gain here can be manually reduced.

P3-15 Flux Brake Gain 0 ～ 200 0
☆
This parameter can suppress the bus voltage rise during the deceleration process of the inve-
rter. The larger the value, the better the suppression effect.
The magnetic flux braking is to increase the motor terminal current by increasing the output
voltage of the inverter, thereby improving the consumption capacity of the feedback energy
and suppressing the rise of the bus voltage. The greater the gain, the greater the motor cur-
rent, so please pay attention in the application. It is recommended to set this value to 0 when
there is a braking resistor at the same time, otherwise an abnormality may occur due to the
large deceleration current during deceleration.
