steady-state-oscillation, and maybe the speed static will occur.
Speed loop parameter PI has strong relationship with the system’s inertia, in order to
meet the requirement of any situation; the PI should be adjusted based on the default
set when the load of the system changed.
P3.02 and P3.06 are filter times of motor speed detection which need not to be
adjusted, increase the values if there is current noise when motor is running.

Note: The above parameters are related to the ACR adjustment, which directly
affects the dynamic response and control accuracy if the system. Generally, the
user can not modify the value.

The parameter is used to adjust the slip frequency of vector control and improve the
precision of speed control. Properly adjusting this parameter can effectively restrain
the steady-state error.
CHV180 series inverter can set electromotion state and regenerate brake state
separately; P3.10 is suitable for electro motion state. P3.11 is suitable for regenerate
feedback state.
