Ref.1.1(1) Correcting the PV (1. Using PV input filter and PV input bias)

Filtering and biasing functions are available with all the UT/UP series models.

■ PV input filtering can be used to remove noise from a PV input that contains high frequency noise,

such as flow rate and pressure signals.

The PV input filter provides first-order-lag computation. Setting a larger time constant (as a parameter value) can increase the amount of noise removed. This filtering is also used to improve controllability and for phase compensation. The time constant of the PV filter is offered as an operating parameter and can be changed during operation.

IM 05J01B02-01E 5th Edition : Mar.25,2005-00

Ref. 1-2

■ PV input biasing adds a constant bias value to the PV input value, and the result is used for the

controller display and control computation.

PV input value PV value inside the controllerPV input bias

In some cases, the measured value is smaller than the actual value by a constant amount due to the physical circumstances at the sensor point. For example, the ambient temperature inside a furnace is often measured instead of the material’s temperature. In such cases, add a constant value for biasing. When the PV value is within the allowable accuracy range but there is a dispersion in PV readings between other equipment, it is possible to use this function for fine adjustment.

Here we explain how to display the parameter setting display and to change the parameter values. Before carrying out these operations be sure to refer to the User’s Manuals Initial Settings and Parameter Map of the controller. The parameter map is very helpful in finding the path to the setting display for a particular parameter.

1: Referring to the User’s Manual above, display

the operating parameter main menu [LP1] (Note1). Then, display the submenu [P AR].

Note1: If the UP/UT mode has been set for using loop-2 or the

secondary loop, also set the corresponding parameters under the main menu [LP2] in the same way.

2: Press the

SET/ENT

key 3 times* to display the PV input bias parameter BS. * Depends on the controller mode. Pressing the

SET/ENT

key one more time displays

the PV input filter parameter FL.

3: In each of these parameter setting displays,

■ Ten-segment Linearizer Biasing

This function is used to correct an input signal affected by sensor deterioration. The corrected values (b) are obtained by adding the corresponding bias values to each of the 1 1 points of optionally set input values (a). The input values used to configure the ten-segment linearizer are set with parameters 1.a1 to 1.a1 1 (Note). The bias values (b-axis) for each of the input values (a) are set with parameters 1.b1 to 1.b1 1 (Note).

Note: • 1.a1 to 1.a11 and 1.b1 to 1.b1 1 are the parameters for UP750, UP550, and UT750.

• 1.A1 to 1.AB and 1.B1 to 1.BB are the parameters for UT550, UT551 and UT520.

• If the UP/UT mode is set for using loop-2 or the secondary loop, “2.a1 to 2.a11 and 2.b1 to 2.b11,” and “2.A1 to 2.AB and 2.B1 to

2.BB” can also be used.

■ Ten-segment Linearizer Approximation

This function is used when the input signal and the required measurement signal have a non-linear relationship. For example, when trying to obtain the volume from a sphere tank level. As shown in the figure below, the output values (b) can be optionally set to 11 points of the optionally set input values (a). The input values used to configure the ten-segment linearizer are set with parameters 1.a1 to 1.a1 1 (Note). The corrective values (b-axis) of ten-segment linearizer approximation for each of the input values (a) are set with parameters 1.b1 to 1.b1 1 (Note).

Note: • 1.a1 to 1.a11 and 1.b1 to 1.b1 1 are the parameters for UP750, UP550, and UT750.

• 1.A1 to 1.AB and 1.B1 to 1.BB are the parameters for UT550, UT551 and UT520.

• If the UP/UT mode is set for using loop-2 or the secondary loop, “2.a1 to 2.a11 and 2.b1 to 2.b11” and “2.A1 to 2.AB and 2.B1 to 2.BB” can also be used.

Ref.1.1(4) Changing the PV sampling period

CAUTION

When the controller is shipped, the PV sampling period is already set to values suitable for implementing the model’s functions and specifications. Therefore, under normal conditions, the default sampling period should be used with the controller and changing it to a shorter one may disable some of the controller’s functions. The sampling period should only be changed if you fully understand the procedures described in the following section.

CAUTION

The response time in communication may be longer when change the PV sampling period shorter. In this case, reset the PV sampling period longer.

The PV sampling period can be changed with UP750, UP550, UT750, UT550, UT551 and UT520.

Ref.1.1(5) Checking that the changed PV sampling period is appropriate

CAUTION

When you have changed the PV sampling period according to “Ref. 1.1 (4) Changing the PV sampling period” in this section, be sure to check that the new period is appropriate by referring to the following descriptions.

It is necessary to check the new period with UP750, UP550, UT750, UT550, UT551 and UT520 after the PV sampling period has been changed.

It is possible to check whether or not the currently set PV sampling period is appropriate for the controller to perform its required functions. For example, with UT550, the PV sampling period can be selected from 4 periods as shown in Table 1-1-1. However, some of the controller functions will be restricted under the use of each period. Although these limitations are given as “Limitations of controller functions” in “Ref. 1.1 (4) Changing the PV sampling period”, they should be taken only as rough guides. Therefore, you must check whether or not the period is appropriate before you use the controller.Carry out this check at the time of the operation test of the system that uses the controller.

This check is performed by monitoring the sampling error counter. The counter value shows how many times the controller failed to process its operation at the current PV sampling period.(The controller increments the counter value by 1 per 10 ms of control period delay when it cannot execute all the processing within the specified period.)

PV sampling period

Processing

This chart shows that processing cannot be executed within the specified sampling period. In this example, the processing is delayed by 30 ms so the sampling error counter is incremented by 3.

Fig. 1-1-5 PV Sampling Period

Processing Processing

30ms

If the counter value is not “0,” it means that some of the processing of the controller remains unprocessed. For this reason, if an exact control is required, set the sampling period so that the counter value will not increase unless a long time has elapsed. If the counter value increases in a short period of time, change the sampling period to a larger value. Y ou can monitor the counter value through the display of setup parameter SMEC (or SMC for UT5) as shown in the following.

1.1 (1) Correcting the PV (1. Using PV filter and PV bias)” of this section. To use the PV filter and PV bias, operating parameters FL and BS are used. As they are operating parameters, their settings can be changed during operation. Therefore, it is recommended that under normal circumstances you use FL and BS. As for “analog input bias” and “analog input filter ,” read the following description and only set them if necessary .

Sensor input value correction is available with UP750, UP550, UT750, UT550, UT551 and UT520. Analog input bias is used to correct sensor-input characteristics, compensating lead wire errors, and so on.

Normally , the PV biasing (BS) is convenient as mentioned in the CAUTION above, however, use the analog input bias (A.BS) in cases where a constant correction is required due to sensor deterioration or for other reasons. Since this biasing is set using a setup parameter , it is suitable for input correction where once the parameter is set, it will not be changed for a long time.

The analog input filter is used to remove noise from a PV input signal that contains high frequency noise such as flow rate and pressure signals. This filter provides a first-order-lag calculation, which can remove more noise the larger the time constant becomes (see the figure below). However, an excessively large time constant will distort the waveform. (See the figure below) As mentioned in the CAUTION above, a similar effect can be obtained by using the PV filter (FL). However, an analog input filter should be used in the cases where a constant level of correction is required, such as in an environment that contains a lot of noise.

Ref.1.1(7) Using PV tracking function (UT only)

The PV tracking function is available with UT750, UT550, UT551. UT520, UT450, and UT420. PV tracking is used to prevent a sudden change in PV .

Note: As shown below, PV tracking is turned OFF at the time of shipment. T urn it ON if necessary.

When PV tracking is ON, the controller sets the SP equal to PV temporarily in the event of the following:

• Power-on

• Switching from MAN to AUTO mode

• Switching from STOP to RUN

• Switching the number of setpoint (SP No.)

After SP is equalized to PV, the SP is gradually changed toward the original SP value at a constant rate-of-change (for ramp rate; see the CAUTION below and the following Fig. 1-1-7).

CAUTION

The SP rate-of-change (ramp rate) is set using parameter UPR and/or DNR, which is set to OFF at the time of shipment. To use PV tracking, you must set parameter UPR and/or DNR to a desired ramp rate value. → See “Ref.4.1(4) Changing SP at a ramp rate when SP is switched” in Ref. 4-1: References Related to Target Setpoint (SP). With these parameters OFF, which specifies no ramp rate (ramp rate = 0), PV tracking will not operate.

Parameters RH1 to RL3 are used to set the range used for control within the instrument range. Parameters P.RH1 to P.RL2 (PV range) are used to set the PV ranges used for the controller’s internal computation when the controller performs loop control with PV switching or loop control with PV auto-selector which receives two inputs of different measurement ranges (see Fig. 1-1-8). The parameters are also used to set the PV range for relative humidity data obtained from dry- and wet- bulb calculations in temperature and humidity control. The decimal point position of the PV range can be set with parameters P.DP1 and P.DP2.

Setting Example (1) For UT750 and UT5

The example below shows signal type, units, range and scaling setpoints used for remote input with the UT750, UT550, UT551 and UT520. For example, with analog input-3 (IN3) = 41, the remote input range is 1.000 to 5.000 for standard signals (1 to 5 V). Here, for an input range of 2 to 4 V , set as follows.

Maximum value of analog input-3 range (RH3) = 4,000 (Ref.: “3,500” means 3.5 V.) Minimum value of analog input-3 range (RL3) = 2,000

Step1: This example shows a remote input range of 1.000 to 5.000 for standard signals

(1 to 5 V) for an analog input -3 type (IN3) = 41.

Step2: In this example, the remote input range is set as 2.000 to 4.000V using the parameters

RL3 and RH3.

Step3: With the UT750/UT5 the same units and decimal point position set for the PV

input range are used for the remote input range. For this reason, if the PV input range is set to a thermocouple type K ( -270.0 to 1370.0 C) the initial value of SL3 is set to “-270.0” and that of SH3 is set to “1370.0” .

Step4: Change the initial settings of SDP3,SL3 and SH3 to the actual values for the remote

Input range. In this example, the SDP3 is set to “2” and SL3 is set to “10.00” and the SH3 is set to “50.00”.
