PID control Proportional (P) action suppresses overshoot and hunting, Integral (I) action corrects offset, and Derivative (D) action converges rapid temperature change due to disturbance in shorter time.
8.3 Selecting Direct/Reverse Action Selects Direct or Reverse control action. Select Direct or Reverse control action in [Direct/Reverse action] in Sub setting mode. Factory default value is Reverse action. Direct action In Direct action, MV is increased when PV is higher than SV (positive deviation). Refrigerators, etc. perform Direct action. MV Low High PV SV (Fig. 8.3-1) Reverse action In Reverse action, MV is increased when SV is higher than PV (negative deviation). Electric furnaces, etc.
8.4 Performing Fixed Value Control Fixed value control is a typical temperature control action, which reduces deviation from a single SV by comparing with PV. To perform Fixed value control, set the SV. There are 2 ways to set the SV. • Set the SV in [SV1] in Initial setting mode. • Set the SV in [SV1] in Main setting mode. Setting item [SV1] in Initial setting mode corresponds to [SV1] in Main setting mode. Therefore, if one SV1 is changed, the other SV1 will also be changed.
8.5 Setting PID Constants (by Performing AT) Notice • Perform the AT during the trial run. • During the AT, none of the setting items can be set. • If power failure occurs during the AT, the AT stops. • If AT is cancelled during the process, P, I and D values revert to the values before AT was performed. • AT will be forced to stop if it has not been completed within 4 hours. • Sometimes the AT process will not fluctuate if AT is performed at or near room temperature.
[C] If there is a large difference between the SV and PV as the temperature is falling When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 higher than the SV. Temperature 20 Temperature higher than the SV (1) Calculating PID constants (2) PID constants calculated (3) Controlled by the PID constants set by AT. (4) AT bias value (Factory default: 20 ) (4) SV Time AT starting point (1) (2) (3) (Fig. 8.
(Example) Performing Usual AT Power ON RUN mode PV/SV Display + Sub setting mode AT/Auto-reset Perform/Cancel or Select AT Perform. RUN mode PV/SV Display Now, selection is complete. The AT indicator flashes while AT is performing. After AT is complete, the AT indicator goes off, and control is performed using PID constants calculated by the AT. If AT does not finish after 4 hours, the error code below will be indicated in the PV Display, and AT will automatically stop.
8.6 Performing Auto-reset Notice • Auto-reset is cancelled in approximately 4 minutes. It cannot be released while performing this function. • If input is burnt out, Auto-reset will be forced to stop. Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the proportional band during the PD control. Since the corrected value is internally memorized, it is not necessary to perform the auto-reset again as long as the process is the same.
8.7 Performing Program Control In Program control, SV changes as time elapses, and PV is controlled to order to reach each SV. SV and time can be set for every step, and a maximum of 9 steps can be repeatedly controlled. SV can be set as (Fig. 8.7-1). (e.g.) Program control of electric furnaces in ceramic manufacture, food machinery, etc. Temperature Step Time (Fig. 8.7-1) Major functions of Program control are shown below.
Program control Holding/Not holding During Program control, progress of current step is suspended (on hold). Fixed value control is performed using the SV from the point of suspension. Program control Holding/Not holding can be selected in [Event input DI1/DI2 allocation]. Advance function Interrupts current step while Program control is running, and proceeds to the beginning of the next step. By pressing the key for approx. 1 second during Program control, Advance function initiates.
Program start temperature When Program control starts, it starts from the value set in [Program start temperature]. Factory default value is 0 . Program control start type One type can be selected: PV start, PVR start, SV start. Factory default value is PV start. Program control start type PV start PVR start SV start Description When Program control starts, the SV and step time are advanced to the PV, then Program control starts.
Select ‘Program control’ in [OUT/OFF key function] in Engineering mode. Factory default value is Control output OFF function. Set the following items in Engineering mode: Step time unit, Power restore action, Program start temperature, Program control start type, Number of repetitions Program pattern can be set in Main setting mode.
(Example) Selecting Program control and Setting program pattern of (Fig. 8.7-6) Power ON RUN mode PV/SV Display + (3 sec) Engineering mode Set value lock (Many times) OUT/OFF key function or Select (Program control). (Many times) or (3 sec) RUN mode Standby (Program control waiting) Main setting mode Step 1 SV or Set to 200 . Step 1 time or Set to 1:00. Step 1 wait value or Set to 10 . Step 2 SV or Set to 200 . Step 2 time or Set to 2:00.
Step 2 wait value or Set to 0 . Step 3 SV or Set to 300 Step 3 time or Set to 0:30. Step 3 wait value or Set to 10 . Step 4 SV or Set to 300 . Step 4 time or Set to 1:00. Step 4 wait value or Set to 0 . Step 5 SV or Set to 0 .
Step 5 time or Set to 2:00. Step 5 wait value or Set to 0 . (Many times) or (3 sec) RUN mode Standby (program control waiting) mode Now, selection is complete. Program control RUN To perform Program control, press and hold the key for approx. 1 second in Standby (program control waiting) mode. Program control starts using the start type selected in [Program control start type]. While Wait function is working, the PV Display flashes.
8.8 Event Output EV1 Allocation Selects Event output EV1 allocation. There are 2 methods in selection of Event output EV1 allocation. • Select in [Event output EV1 allocation] in Initial setting mode. • Select in [Event output EV1 allocation] in Engineering mode. Setting item [Event output EV1 allocation] in Initial setting mode corresponds to [Event output EV1 allocation] in Engineering mode.
(Example) Selecting High limit alarm, and setting EV1 alarm value to 20 Power ON RUN mode PV/SV Display + (3 sec) Initial setting mode Input type (3 times) Event output EV1 allocation or Select (High limit alarm). (2 times) EV1 alarm value or Set to 20 . (Many times) or (3 sec) RUN mode PV/SV Display Now, settings are complete.
8.9 Indicating MV, Remaining Time (Program Control) In Fixed value control and Program control, MV and remaining time are indicated. To indicate MV, press and hold the key for approx. 3 seconds in PV/SV Display. The unit enters Monitor mode, and indicates MV. While MV is indicating, the decimal point flashes. While in Standby (Program control waiting) mode of Program control, the unit cannot move to Monitor mode. In Monitor mode, the following contents are switched every time the key is pressed.
8.10 Items to be Initialized by Changing Settings The following shows items to be initialized by setting changes.
9. Attached Function 9.1 Input Value Correction Input value can be corrected in [Sensor correction coefficient] and [Sensor correction] in Engineering mode. In [Sensor correction coefficient], set the slope of temperature change. In [Sensor correction], set the difference between temperatures before correction and after correction. PV after input correction is expressed with the following formula.
(Example) Setting Sensor correction coefficient to 0.800, and Sensor correction to 100.0 Power ON RUN mode PV/SV Display + (3 sec) Engineering mode Set value lock (Many times) Sensor correction coefficient. or Set to 0.800.
