3 Enhanced functionality which makes PXF suitable for a wide range of application The following functions are provided as standard: on/ control, PID control, fuzzy control, degreesreedom PID, openloop control, selftuning, PID autotuning. ou can configure each function by front face keys or by parameter loader.. On/ control When process value () is below the set value (), output is turned on and the heater is energized as shown below. When is above, output is turned and the heater is deenergized. In this way, output is turned on/ repeatedly with respect to the to keep the temperature constant. This method of control is called "on/ action (position action)" * When "" is assigned to parameter P, the on/ action will be selected. Control characteristic of / action Hysteresis. Fuzzy control Fuzzy control is used to suppress overshoot so that the response to external disturbance is improved. y monitoring, overshoot is suppressed with startup time remaining unchanged. t the same time, response to external disturbances is also improved. Comparison between fuzzy control and conventional control Fuzzy control Conventional control Overshoot response to disturbances Overshoot response to disturbances Heater 3. degreesreedom PID control This function achieves stable control against external disturbances, while suppressing overshoot and undershoot at startup or at change. Conventional PID degreesreedom PID (before adjusting and ) Process value Process value. Openloop system supported PXF can be used on control equipment with openloop system in which a heater is forcibly turned. The controller can minimize an overshoot which occurs at a transfer from openloop to closedloop. Process value Overshoot is controlled degreesreedom PID (with optimal and ) Process value to control equipment t Control loop Close Open Close. Self tuning t power on, change, or during external disturbance, tuning is made automatically so that the PID parameters are reoptimized.. PID auto tuning PID parameters are automatically set by the controller's measurement and computation function. This instrument provides types of autotuning functions; the standard type (autotuning with used as reference) and the low type (autotuning with the value % below used as reference). (a) Standard type T start T end (PID setup) T computation (b) Low type T start T end (PID setup) T computation External disturbance change Power on Note: For some objects to control, PID values can not be optimized.

4 variety of functions extending the possibility of temperature controller. Ramp soak function (simple program control) Overview This function allows the controller to change to the preset values at preset times. ou can choose up to steps for setting and types of operation patterns. TMr Example of steps x patterns step step 3 step 3 step to : pattern step to : pattern step to : pattern 3 step 3 to : pattern 3 TMs TMs TMr TMr TMs Guarantee soak This function guarantees the soak time. Only soak time within the specified range of temperature for is counted towards soak time. s seen in the figure below, only the sum of the shaded areas is counted as soak time. The operation moves onto the next step when the total soak time has reached the specified soak time. Process value Guarantee soak range upper limit Guarantee soak range lower limit Soak time = T T T3 T T T3 t asic functions [] unit setting: "Hour, Minutes" or "Minutes, Seconds" [] Guarantee soak [3] Repeat action [] start [] Delay start [] Power restoring function Number of steps and patterns No. of steps No. of patterns 3 Operating method ou can start, stop, or suspend the operation by using the assigned key, by setting parameter, or via communication. Status output The following items can be output by digital output. you can use external devices to perform the operation. Running/stopped/suspended/in guarantee soak/end signals. and PID selection This function allows you to register up to sets of and PID setting, and to switch among them. It enables you to select optimum PID setting for changed process or materials, or for. ou can perform selection only, or PID selection only. Palette Palette Palette 3 P P P I I I D D D RH RH RH RL RL RL Palette P I D RH RL Selection select Selecting parameter Digital Userdefined key Communication PID operation 3. Soft start. Simple powermonitoring function and endoflife alarm This function prevents MV from being maximum output when the equipment (including the temperature controller) is turned on. It is useful in suppressing heater output at startup to reduce a load.
