AuxPIDX_Kc
Tip Strip: PID proportional gain
Detail: Proportional gain. A value of zero disables proportional, integral, and derivative contributions to the
PID output. (See the equation above for reference.) Smaller values cause less proportional contribution to
the PID output. Larger values cause more proportional contribution to the PID output. Negative values will
generate PID outputs that are inversely proportional to the error (Setpoint – Process Variable).
AuxPIDX Kc_Action
Tip Strip: Proportional contribution of PID controller
Detail: Indicates the contribution of the proportional term to the total PID output.
AuxPIDX_Ti
Tip Strip: Integral time constant for PID controller (lower = stronger action. 0 = disabled.)
Detail: Integral time constant. A value of zero disables integral contribution to the PID output. Smaller non-
zero values cause more contribution to the PID output. Larger values cause less contribution to the PID
output. Negative values should not be used.
AuxPIDX Ti_Action
Tip Strip: Integral contribution of PID controller
Detail: Indicates the contribution of the integral term to the total PID output.
AuxPIDX_Td
Tip Strip: Derivative time constant for PID controller (higher = stronger action. 0 = disabled.)
Detail: Derivative time constant. A value of zero disables derivative contribution to the PID output. Smaller
values cause less contribution to the PID output. Larger values cause more contribution to the PID output.
Negative values should not be used.
