E5@C Digital Temperature Controllers User’s Manual (H174)
These parameters set PID control constants. PID constants are automatically set when AT or ST is exe-
cuted.
rsrt
Remote SP Input Slope Coefficient
There must be a remote SP input.
This parameter sets a factor to apply to the remote SP input to compensate it. The resulting
value is displayed as the remote SP input value and used in control.
p
Proportional Band
The control must be set to 2-PID control.
i
Integral Time
d
Derivative Time
P
action:
Refers to control in which the MV is proportional to the deviation (control error).
I
action:
Refers to a control action that is proportional to the time integral of the deviation.
With proportional control, there is normally an offset (control error). Proportional
action is thus used in combination with integral action. As time passes, this control
error disappears, and the control temperature (process value) comes to agree
with the set point.
D
action:
Refers to a control action that is proportional to the time derivative of the control
error. The proportional control and integral control correct for errors in the control
result, and thus the control system is late in responding to sudden changes in
temperature. The derivative action increases the MV in proportion to the slope of
the change in the temperature as a corrective action.
