12.7.3 P402 PID Process Value Source
Determines the source of the process value (P402 – 01 or – 02) for the corresponding PID
system (1 or 2)
The process value is the value that the controller is trying to match with the setpoint (
f
= 1)
Enter:
1 = rate
f
2 = load
3 = mA input 1
4 = mA input 2
12.7.4 P405 Proportional Term
Sets the proportional term (P405-01 or -02) for the corresponding PID system (1 or 2) (
f
= 0.400)
The proportional term is the proportional gain. A gain of 1 is equivalent to a proportional band of
100%.
The proportional band is the range of deviation from the setpoint that corresponds to the full
range or the control output.
Enter the proportional term 0.000 to 2.000.
12.7.5 P406 Integral Term
Sets the integral term (P406-01 or -02) for the corresponding PID system (1 or 2) (
f
= 0.200)
Enter the integral term 0.000 to 2.000.
12.7.6 P407 Derivative Term
Sets the derivative term (P407-01 or -02) for the corresponding PID system (1 or 2) (f = 0.050)
Enter the derivative term 0.000 to 1.000.
12.7.7 P408 Feed Forward Term
Sets the feed forward term (P408-01 or -02) for the corresponding PID system (1 or 2) (f =
0.300)
Enter the feed forward term 0.000 to 1.000.
