Chapter 2 Control Register
2-27
Reduce P gain
Prevent overshooting, which would
cause longer time to achieve the
target temperature with a slower
convergence speed.
I gain
Increase I gain
(Decreasing integral time Ti)
As increasing Overshoot,
oscillation amplitude would be
increased as well, so as to reach
the target temperature with a
faster convergence speed.
Decrease I gain
(Increasing integral time Ti)
The convergence speed would be
slower to minimize overshoot and
oscillations.
D gain
Increase D gain
Changes in temperature would be
eased.
Decrease D gain
Changes in temperature would
become rapid.
Special case
To improve the situation that
temperature constantly oscillates
over the SV, decrease D gains or
simply control with PI
.
