  • Page 29: Program Pattern Functions

    Program Pattern Functions The program pattern function allows performing a program operation by changing the setpoint in conjunction with the time according to the preset program pattern. A program pattern consists of multiple segments. A program pattern can be created by setting the final target setpoint and segment time. The use of the program pattern-2 retransmission function allows creating a program pattern for retransmission.

  • Page 92 6.4 Adjusting PID Manually There are 16 groups of PID parameters. In Cascade control, both Loop-1 and Loop-2 have 16 groups.

  • Page 93 6.4 Adjusting PID Manually Description Description and Tuning of Proportional Band The proportional band is defined as the amount of change in input (or deviation), as a percent of span, required to cause the control output to change from 0% to 100%. Because a narrower proportional band gives greater output change for any given deviation, it therefore also makes the control performance more susceptible to oscillation.
  • Page 94 6.4 Adjusting PID Manually Description and Tuning of Integral Time The integral action (I action) is a function that will automatically diminish the offset (steady-state deviation) that is inherently unavoidable with proportional action alone. The integral action continuously increases or decreases the output in proportion to the time integral of the deviation (the product of the deviation and the time that the deviation continues.) The integral action is normally used together with proportional action as proportional- plus-integral action (PI action).
  • Page 95 6.4 Adjusting PID Manually Description and Tuning of Derivative Time If the control object has a large time constant or dead time, the corrective action will be too slow with proportional action or proportional-plus-integral action alone, causing overshoot. However, even just sensing whether the deviation is on an increasing or a decreasing trend and adding some early corrective action can improve the controllability. Thus the derivative action (D action) is action that changes the output in proportion to the deviation derivative value (rate-of-change).
  • Page 96 6.4 Adjusting PID Manually Manual PID Tuning Procedure (1) In principle, auto-tuning must be used. (2) Tune PID parameters in the order of P, I, and D. Adjust a numeric slowly by observing the result, and keep notes of what the progress is. (3) Gradually reduce P from a larger value. When the PV value begins to oscillate, stop tuning and increase the value somewhat.
