Simultaneous temperature rise function• This function ensures uniform temperature by synchronizing the set value arrival time of two or more loops. Save energy and reduce running costs by avoiding idle time.

Self-tuning function• This function automatically adjusts the PID constant while in operation.The cost (time, material, and electric power) of auto tuning can be reduced.

When two or more loads are being controlled, the peak current can be minimized by spreading the total load out over time.

Features

Point 1Point 1 Highly stable temperature control

Prevent overheating and overcooling in devices which require a high level of temperature stability, such as in an extrusion molding machine. In addition to standard temperature control (heating or cooling), control of cooling may be performed.Furthermore, mix control (a combination of heating and cooling control) can be performed.

Standard control/heating and cooling control

Point 2Point 2 Convenient functions make this module easy to use!

This function reduces the peak current by automatically adjusting the upper bound and output limiter of each channel and dividing transistor output timing. Output timing can be split between up to 4 outputs.

Peak current control function

Example: Standard control (heating)

The temperature of the object is controlled by adjusting the heater output based on the PID calculations resulting from the temperature sensor input.

Example: Heating-cooling control (heating and cooling elements controlled simultaneously)

Heating is performed when the control object's temperature is lower than the target temperature, and cooling is performed when it is hotter or the humidity needs to be reduced.

Using this function, it is possible to coordinate the control of two or more loops to reach their target values (SV) at the same time. Control the simultaneous rise in temperature of separate loops by setting a channel group (Max. 2 groups)

This is an effective way to control applications where differing target temperature arrival times can result in undesirable temperature differentials.

Using this function, 2 or more control loops can be set to reach their set values at the same time.Perform a uniform temperature rise using two or more control loops without going over temperature or resulting in unexpected thermal expansion.

Item Description

Standard control

Heating -coolingcontrol

Control mode selection functionThe control mode can be selected from the following modes. • Standard control • Heating-cooling control (normal mode) • Heating-cooling control (expanded mode)• Mix control (normal mode) • Mix control (expanded mode)

Output setting at CPU stop errorWhether to clear or hold the transistor output status when a CPU stop error occurs or when a CPU module is turned from RUN to STOP can be selected.

Control methodThe following control methods can be used with the settings of proportional band (P), integral time (I), and derivative time (D).• Two-position control • P control • PI control• PD control • PID control

Manual reset function The stable status position in the P control or PD control can be moved manually.

Manual control The manipulated value (MV) can be set manually by users without automatic calculation by the PID control.

Auto tuning function The Q64TCN sets the optimal PID constants automatically.

Simple two-degree-of-freedomIn addition to the PID control, the response speed responding to the change of the set value (SV) can be selected from three levels.The simple two-degree-of-freedom PID control can be realized.

Derivative action selection function Dynamic performance can be improved by selecting the suitable derivative action for the fi xed value action and the ramp action.

Setting change rate limiter setting function

Change rate setting of the set value (SV) per set time unit when this value is changed. The batch setting or individual setting can be selected for the temperature rise and drop.

Temperature process value (PV) scaling function

The temperature process value (PV) can be converted to the set width and this value can be imported into the buffer memory.

Alert function The modules goes to the alert status when the temperature process value (PV) or deviation (E) meets the condition set in advance.

RFB limiter functionWhen the deviation (E) continues for a long time, the PID operation result (manipulated value (MV)) by the integral action can be prevented from exceeding the effective range of the manipulated value (MV).

Sensor compensation function

If a difference between a temperature process value (PV) and an actual temperature occurs due to the measurement status, the error can be corrected. Select a correction method from the following two types.• 1-point sensor compensation (standard) function: The percentage of the full scale of the set input range can be corrected as an error

corrected value.• 2-point compensation function: An error is corrected by setting any two points (corrected offset value and corrected gain value).

Auto-setting at input range changeWhen the input range is changed, the related buffer memory data is changed automatically so that errors outside the setting range does not occur.

Input/output (with another analog module) function

Data can be input/output using another analog module (A/D conversion module or D/A conversion module) on the system.

ON delay output function Setting with considering delay time (response/scan time delay) of actual transistor output is possible.

Self-tuning functionThe Q64TCN monitors the control status constantly. If the control system oscillates due to a status soon after the control starts, a change of the set value (SV), and property fl uctuation of a controlled object, PID constants are changed automatically.

×

Peak current suppression functionChanging automatically the upper limit output limiter value of each channel and dividing the timing of transistor output can suppress the peak current.

Cooling method setting functionWhen the auto tuning is executed, an auto tuning formula is automatically selected according to the selected cooling method and the operation starts.

×

Overlap/dead band functionBy changing the temperature where the cooling transistor output is started, whether control stability is prioritized or energy saving is prioritized can be selected.

×

Temperature conversion function (using unused channels)

In heating-cooling control (normal mode) and mix control (normal mode), only temperature measurement is allowed by using unused temperature input terminals.

×

Heater disconnection detection function The current which fl ows in the heater main circuit can be measured and disconnections can be detected.

An error of when the transistor output is off can be detected.

Buffer memory data backup function The buffer memory data can be stored and backed up in the E2PROM.

Error history function Up to 16 errors and alarms that occur on the Q64TCN are stored in the buffer memory as history.

Module error history collection function

Error contents can be notifi ed to the CPU module when errors and alarms occur on the Q64TCN. Error information is held in the memory inside of the CPU module as module error history.

Error clear function When an error occurs, the error can be cleared on the system monitor.
