The recommended adjustment method is as follows:
If the factory parameters can not meet the requirements, fine-tuning should be carried out on the basis of the
factory parameters. Firstly, the proportional gain should be increased to ensure that the system does not oscillate;
Then, the integration time is reduced to make the system have faster response characteristics and smaller
overshoot.

Vector slip compensation gain
For vector control (P0-01=1 or 2), this parameter can adjust the speed stabilization accuracy of the motor.
For example, when the motor operating frequency is lower than the output frequency, this parameter can be
increased.
For vector control with speed sensor (P0-01=2), this parameter can adjust the output current of inverter under
the same load.
For example, in high-power inverter, if the load capacity is weak, this parameter can be gradually reduced.
Note: In general, it is not necessary to adjust this parameter.
SVC speed feedback filter time
The speed feedback filtering time of SVC takes effect only when P0-01 = 0. Increasing P6-08 can improve the
stability of the motor, but the dynamic response becomes weak. On the contrary, the dynamic response becomes
stronger, but too small will cause the motor vibration. In general, it no needs to adjust.
Speed control (drive) torque upper
limit source
Full scale of 1~7 corresponds to P6-11
Speed control (drive) torque upper
limit digital setting
In speed control mode, the maximum output torque of the inverter is controlled by the torque upper limit source.
P6-10 is used to select the setting source of torque upper limit. When setting through the analog quantity, pulse
and communication, the corresponding setting 100% corresponds to P6-11, while the 100% of P6-11
corresponds to the rated output current of the inverter.
The setting of AI1, AI2 and AI3 is described in the relevant description of AI curve of group P2 (corresponding
curve is selected through P2-54), and pulse is described in P2-66~P2-70.
When the torque upper limit source is set as communication setting, the torque value is given through the
mapped U4-06.
