This gain determines the proportion controller’s
impact on feedback deviation. The greater the
gain, the faster the impact. Yet a gain that is too
big will cause vibration
.

This parameter is use to set integral controller’s
integral time. When the integral gain is too big,
the integral effect will be too weak to eliminate
steady deviation. When the integral gain is too
small, the system vibration frequency will
increase, and therefore the system may be
unstable.

This gain determines deviation controller’s
impact on the amount of change of the
deviation
.
Appropriate deviation time can reduce the
overshooting between the proportion controller
and the integral controller. Yet when the
deviation time is too large, system vibration may
be induced.
