Page 71 6.3 Performing and Canceling Auto-tuning Description Auto-tuning is a function with which the controller automatically measures the process characteristics and sets PID constants, which are control-related parameters, to optimum values for the setpoint. Auto-tuning temporarily executes ON/OFF control, calculates appropriate PID constants from response data obtained, and sets these constants. CAUTION Do not perform auto-tuning for the following processes.
Page 72 6.3 Performing and Canceling Auto-tuning Tuning Point and Storage Location of Tuning Results The tuning point when performing auto-tuning is the target setpoint that is currently used for control computation. PID constants after the tuning are stored in the PID group that is specified when performing auto-tuning.

In the Setting Display for the PID parameters, Displays can be arbitrarily switched using the Up, Down, Left or Right arrow...
Page 74 6.4 Adjusting PID Manually There are four groups of PID parameters. The PID parameters can be selected by using the following two methods: (1) SP group number selection The PID group which is set in the PID number selection (PIDN) of each SP group is used.
Page 75 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. At the same time, a narrower proportional band reduces the offset.
Page 76 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 77 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 78 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. (4) Also gradually reduce I from a larger value. When the PV value begins to oscillate (with long period), stop tuning and increase the value somewhat. (5) Gradually increase D from a smaller value. When the PV value begins to oscillate (with short period), stop tuning and lower the value slightly.

8.2 Setting Control Type (CNT) 8.2.2 ON/OFF Control (1 point of hysteresis / 2 points of hysteresis) Description ON/OFF control compares the SP and PV and outputs an on or off signal according to the positive or negative deviation (PV – SP). Hysteresis can be set in the vicinity of the on/off output operating point. If the SP and PV become close and the polarity of the deviation reverses frequently, the on/off output will cycle repeatedly. The life of the output relay will therefore be dramatically shortened. In such a case, set a wider hysteresis so that the relay’s frequent on/off output (chattering) will not occur.

To avoid this, the controller provides an anti-reset wind-up function for suppressing an extreme integral output by stopping PID computations. Same applies to the case of undershoot.
