Page 66: Program Patterns
Chapter 5. FUNCTIONS 5 - 2 Program Patterns ■ Patterns SP and time comprise the settings for a single segment in a pattern. Up to 30 segments can be linked to create a broken-line whose verti- cal axis is SP and horizontal axis is time. This system is called the “RAMP-X” system. SP setting: Within range of SP limitter upper and lower limits Timesetting: 0 to 99 h, 59 min or 0 to 99 min, 59s (Select the time unit in setup data C 6 4.) SP is the point that corresponds to the time elapsed in the current segment on a straight line made by jointing the start point (SP set- ting value of the previous segment) to an end point (SP setting value of the current segment). Accordingly, segments are categorized as follows: • R ising ramp (rising ramp, rising tendency) Previous segment SP setting value < current segment SP setting value • F alling ramp (falling ramp, falling tendency) Previous segment SP setting value > current segment SP setting value • S oak (soak) Previous segment SP setting value = current segment SP setting value In the case of the No.1 segment, both the start and end points be-...
Page 67 Chapter 5. FUNCTIONS ■ Events 1 to 3, Time events 1 to 5 In event configuration data setup, they are used after setting the event type, event standby, hysteresis and ON delay time. A total of four event types which are PV type events, controller status events, time events and segment number events are available. Segment number events can be set by time events 1 to 5 only. In the constant-value operation mode, the time events 1 to 5 do not function. ● PV type events ● • B asic specifications T he next page shows event type PV, deviation, absolute value deviation, SP, MV and MFB.

FUNCTIONS • Segment progression - O utput is OFF until the program progresses to the segment containing the event setting. - W hen the program progresses to the segment containing the event setting, event ON/OFF operation is carried out according to the event setting value. - T he previous setting is valid until the program progresses to a segment containing a new event setting. F or this reason, set as follows to disable the event set in the previous segment from a certain segment onwards: Direct action events: Upper limit value of event setting Reverse action events: Lower limit value of event setting N ote, however, that some types of event turn ON even if events are set as shown above. - W hen the program has progressed to the No.1 segment by the cycle or pattern link functions, the previous setting is disabled. Output is OFF unless the No.1 segment contains an event setting. • Other O n 5G output models, when setup data C 1 8 is set to 1, and SP output (programmer functions) is selected, the MV direct/reverse event does not function.

Page 70 ● Controller status events ● Controller status events are turned ON and OFF according to the controller mode, alarm status and other statuses. Though the event standby function does not function, the ON delay function does. Event setting values (operating point), hysteresis and event standby are not set. • Basic operations The following basic operation types are provided: RUN+HOLD+FAST+END READY HOLD FAST G.Soak standby MANUAL Auto-tuning executing Constant-value operation MFB estimated position control, sum of all alarms PV range alarm Controller alarms Low battery voltage Console setup in progress Loader setup in progress Program end W hen the DCP31 reaches the state designated by the event type, the event is turned ON. Otherwise, the event is OFF. • Alarms A larms are divided into PV range alarm groups (alarm code Nos. 01 to 16) and controller alarm groups (alarm code Nos. 70 to 99, and low battery voltage). W hen the event type is set to the sum of all alarms, the event turns ON if any one of the alarms occurs.
Page 71 Chapter 5. FUNCTIONS W hen the event type is set to PV range alarm, the event turns ON if any one of the alarms in the PV range alarm group occurs. W hen the event type is set to controller alarm, the event turns ON if any one of the alarms in the controller alarm group occurs. • ADV T his is ON for 1s after executing program advance. The event ON delay is disabled and a delay is not applied. • Program end W hen the DCP31 automatically (including ADV) reaches the READY mode from program operation status (RUN, HOLD, FAST) without performing RESET operation, the event is turned ON. When shifting from END mode to READY mode, the event is not turned ON as RESET operation is required. T his event is cancelled (ON→OFF) when one of the following conditions is satisfied: • When RESET operation is performed. • When shifting from READY to RUN mode. • When power is again supplied.
Page 72 Chapter 5. FUNCTIONS ● Time events ● When the event 1 to 3 type is set to time event, the event can be used in the same way as time events 1 to 5. However, note that events 1 to 3 do not have segment No. event functions. Though the event standby function does not function, the ON delay function does. The ON and OFF times or only the ON time can be set for each event No. and segment. The following describes ON/OFF of output: • When the ON time is smaller than the Segment OFF time, output is ON for the duration ON time from the ON time to the OFF time. ON < OFF (See segments 1, 6 and 7 in the figure.) OFF time • When only the ON time is set, output is Output ON ON for the during from the ON time to Output OFF the segment end point.

Page 75: Pid Set Selection
Chapter 5. FUNCTIONS ■ PID set selection • Eight sets of PID parameters, PID1 to PID8, are used for control operation. When the PID set No. is set to each segment by designating the PID set segment, control output is calculated by each of the PID parameters. • There are two ways of selecting PID sets: by des- ignating the PID set segment and PID set auto- PID set No. switching. The method can be selected by setting PID set segment designation setup data C 1 1. C 1 1 set to 0: Designation of PID set segment C 1 1 set to 1: PID set auto-switching These two methods cannot be set simultaneously.

Page 76: G.soak (Guarantee Soak)
Chapter 5. FUNCTIONS ■ G.Soak (guarantee soak) G.Soak ON/OFF and G.Soak width can be set for each segment. The G.Soak time can also be set by the variable parameter G S . t item. The G.Soak function ensures a segment execu- G.Soak width tion time with PV close to SP. G.Soak functions not only in soak segments but also in ramp G.Soak width segments. Segment set time At the segment start point, PV and SP are Segment execution time compared, and the absolute value of the result- ing deviation continues for the G.Soak time or G.Soak standby time Time count start Time longer. When the absolute value is smaller than G.Soak at segment start point the G.Soak width, operation of that segment is started.
Page 77: Pv Start
Chapter 5. FUNCTIONS ■ PV start If PV start is set in the program setup, PV is SP pattern started by regular RUN operation. The first point where PV matches the SP in the Current program pattern (including bias for both PV Start point PV value and SP) is searched for, and operation is started from that point. Start point Start point However, note that if a matching point is not (1)' found, operation is started from the beginning of segment 1. (1)" When PV has started, event operating points and the time of time events are automatically PV start points corrected. If the PV start function is selected (1) PV starts at point A where the PV value first by setup data C 5 2 to C 5 4 settings relating to crosses the SP pattern.
Page 78: Pattern Link
Chapter 5. FUNCTIONS ■ Pattern link “pattern link” is a function for linking pat- Program No.2 pattern-linked to program No.1 terns together. The link destination program No. is set by the Program No.1 pattern link item. When the pattern link item is set to 0 (initial setting), patterns are not linked. When the Time No. of the current program itself is set to the pattern link item, this creates an endless loop. If the SPs at the link source end point and the link destination start point do not match, the Program No.2 SP changes in a stepped manner during link operation. When cycle operation has been set, the pat- Time tern link function works after cycle operation has ended. After pattern link operation ends, operation begins from the No.1 segment of the link destination pattern, so operation is restarted with the settings of events 1 to 3 and time events 1 to 5 cleared. If PV start is programmed to the link destina- Time tion pattern, the PV start function operates Program No.1 Program No.2 after the link is made.
Page 79: Mode
Chapter 5. FUNCTIONS 5 - 3 Modes ■ Mode types The following modes are available on the DCP31: Mode Program operation READY AUTO MANUAL AUTO MANUAL HOLD AUTO MANUAL FAST AUTO MANUAL AUTO MANUAL READY Constant-value operation AUTO MANUAL AUTO MANUAL ● Program operation ● Operation is carried out according to SP, times, events, etc. set to program patterns No.1 to 19.
Page 80 Chapter 5. FUNCTIONS ● READY ● In this mode, the DCP31 is ready for operation. MV output is fixed, and events to be operated according to event setting values turn OFF. However, events to be operated according to controller states are active. Parameters for all of the setup data, some event configuration data and some constantvalue operation data can be set or changed in the READY mode. During program operation, program pattern Nos.1 to 19 can be selected. ● RUN ● In this mode, the program is running. MV outputs are active in PID control or ON-OFF control, and events and time events are active. In the program operation mode, program operation progresses ac- cording to the elapsed time. However, note that progress of program operation stops in the same way as the HOLD mode when the controller is in the G.Soak (Guar- antee Soak) standby state. ● HOLD ● In this mode, the program is held. Progress of program operation stops. However, note that MV outputs are active in PID control or ON-OFF control, and events and time events are active in the same way as in the RUN mode. The HOLD mode is not available during constant-value operation. ● FAST ● In this mode, the program is fast-forwarded. This mode is like the RUN mode except that progress of the pro- gram operation time is speeded up. The time scale is selected by the variable parameter F A S T setting.
Page 81 Chapter 5. FUNCTIONS ● END ● In this mode, operation of the program has ended. MV outputs are active in PID control or ON-OFF control, and events and time events are active with program operation stopped at the program end point. The END mode is not available during constant-value operation. ● AUTO ● In this mode, program operation is automatic. MV output is active according to controller control. (However, note that when programmer functions are selected on 5G output models, SP output is active according to controller control.) ● MANUAL ● In this mode, program operation is manual. MV output can be changed by , , , on the console or communications.

Page 83: Mode Transition Operations
Chapter 5. FUNCTIONS ■ Mode transition operations The following describes mode transition operations: Though “program end” is not an operation, it is described below as it is a factor in mode transition. ● RUN ● This operation involves shifting to the RUN mode from the READY, HOLD or FAST modes. To shift from the READY mode to the RUN mode, the DCP31 must be in the basic display state even in key, external switch input or communication operations. ● HOLD ● This operation involves shifting to the HOLD mode from the RUN or FAST modes. The HOLD mode is not available in the constant-value operation mode. ● RESET ● This operation involves shifting to the READY mode from the RUN, HOLD, FAST or END modes. In the program operation mode, this mode includes returning to the No.1 segment. ● ADV ● This operation involves advancing one segment in the READY, RUN, HOLD or FAST modes. The ADV mode is not available in the constant-value operation mode. ● FAST ●...
Page 84 Chapter 5. FUNCTIONS ● MANUAL ● This operation involves shifting to the MANUAL mode from the AUTO mode. When the DCP31 enters the MANUAL mode, the basic display state changes as follows. - When controller functions are selected, PV and output value (%) are displayed. - When programmer functions are selected, PV and SP are displayed. When the DCP31 enters the MANUAL mode from the AUTO mode by external switch inputs or communications, the display changes to the basic display state even in the parameter setup or program setup states. ● Program end ● When operation progresses in the RUN or FAST modes in the program operation mode, or when the segment has been advanced in the ADV mode, the program ends when all end points in the pro- gram setup including cycles and pattern links have been reached. You can select in the setup setting in which of the READY or END modes program operation ends. The program does not end in the constant-value operation mode. 5-20...

Page 109: Auto-Tuning (At)
Chapter 6. OPERATION ■ Auto-tuning (AT) When operating in the AUTO mode in either of the RUN, HOLD, FAST or END modes, setting values can be automatically written to the PID set in use by auto-tuning (AT). The following can be selected by variable parameter A t setting. 0: AT is disabled. 1: General AT is executed. 2: Overshoot-inhibited AT is executed. 3: AT by neural net is executed. • Auto-tuning does not function when programmer functions are selected on 3D or 5K heat/cool output models and 5G output models. • During execution of auto-tuning, progress of program operation time stops. Accordingly, the controller is in a similar state to the HOLD mode even in the RUN or FAST modes. • Auto-tuning in all instances involves calculating the downtime and critical sensitivity of the line according to two limit cycles and PID values according to suitable characteristic equations for each, and automatically writing these PID values. • During execution of auto-tuning, PV fluctuates according to fluctuations in MV. Before executing auto-tuning, make sure that fluctuations in PV will not cause controller trouble. • Normally, suitable values are written by setting variable param- eter At setting to 1 or 3. However, when executing auto-tuning on a line that easily overshoots, either set to 2, or also use smart- tuning for carrying out overshoot inhibit control. Setting to 3 executes AT by neural net so that the suitable value is calculated for wider range applications. • The point at which output at auto-tuning is inverted (lower limit to upper limit, and vice versa) is determined as follows from SP and PV at start of auto-tuning.

These constants are set automatically during AT execution, and is memorized. They can also be set and changed independently.
Page 126 Chapter 7. PARAMETER SETUP • Position-proportional control dead zone On 2G output models, a dead zone between the motor open and mo- tor closed positions is set. As a general guideline, the minimum value is the value where this dead zone changes to stop motor hunting once a fixed value set to manual output is being output. If this value is set without any margin, the motor will be operating at all times, which will considerably shorten its service life. The factory setting is 5 %. Use this as a guideline, and take the con- trol results and motor service life into consideration when setting the dead zone. *: Dead zone setting value Dead zone Closed-side Open-side relay ON relay ON Control output (%) MFB (%) • Heat-cool control dead zone -100 to +50 % Heat-cool control is calculated as follows: Note 4) PID set selection (1 of 4 sets) Heat-side Cool-side...

This state is referred to as “estimated posi- tion control state.” For example, when the motor rotates at a position where the feed- back potentiometer has deteriorated, MFB input changes suddenly. This sudden change is detected as an error, and the correct MFB position is estimated. The motor position is also controlled by the estimated MFB value when the MFB disconnected alarm has occurred. • I n the estimated position control state, an error will inevitably occur between the actual motor valve opening and estimated MFB value. So, set the closed-side relay to ON at all times when output (MV) ≤ 0.0 %, and the open-side relay to ON at all times when MV ≥...

By this function, the DCP31 judges reverse direction wiring in the same way as direct direction wiring, and does not generate an alarm. If the setting of variable parameter .-C is left at the factory setting (“0”), motor operation is continued. The following tables summarize the phenomena that occur according to how the motor and DCP31 are wired when the motor is automatically adjusted (variable parameter .-A T setting 1 is input). Motor rotation is started from the fully closed position (motor is turned as far as possible CCW). The values displayed in the lower display in the tables are only examples. Alarms are displayed after the motor fully closes or fully opens.
