Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

[DESIGN PRECAUTIONS]

WARNING

Do not write data to "read-only area" or "reserved area" in the buffer memory of the intelligent function module. Also do not turn ON/OFF the "reserved" signal in I/O signals to the programmable controller CPU. Doing any of these operations may cause a malfunction of the programmable controller system.

When a transistor for external output fails, the output may be ON or OFF status. Create a circuit for monitoring output signal that may lead to serious accident.

CAUTION

Do not install the control lines and/or pulse input wiring together with the main circuit or power lines, and also do not bring them close to each other. Keep a distance of 150mm (5.91 inch) or more between them. Failure to do so may cause a malfunction due to noise.

[INSTALLATION PRECAUTIONS]

CAUTION

Use the programmable controller in the environment conditions given in the general specifications of the User's Manual for the CPU module. Failure to do so may cause an electric shock, fire, malfunction, or damage to or deterioration of the product.

TROUBLESHOOTING

OVERVIEW

1.1 Features

This section describes the features of the QD64D2.

(1) Counting at the maximum counting speed of 4Mpps is possible. (In 4

multiples of 2 phases)

Since the QD64D2 can be used for high-resolution encoder (e.g. linear scale), the equipment can improve position detection accuracy and a workpiece can be moved at high-speed.

(2) Wide range of expression on counting (from -2147483648 to 2147483647)

Count values can be stored in 32-bit signed binary.

(3) Pulse input selection

Pulse input can be selected from 1 multiple of 1 phase, 2 multiples of 1 phase, 1 multiple of 2 phases, 2 multiples of 2 phases, 4 multiples of 2 phases, and CW/CCW.

(4) Counter format selection

Either of the following counter formats can be selected.

(a) Linear counter format

From -2147483648 to 2147483647 can be counted and an overflow can be detected when the count range is overrun.

(b) Ring counter format

Counts are repeatedly executed between the ring counter upper limit value and ring counter lower limit value.

(5) Coincidence detection

The QD64D2 can compare the present value and comparison point, notify the comparison result with input signal, and start an interrupt program when they match. It also mounts 2-point external coincidence output for each channel, which permits controlling external devices at high-speed.

According to application, select the coincidence output function or continuous comparison function.

(a) Coincidence output function

Set 1 as the coincidence detection point for each point to compare it with the present value. Reset the coincidence output signal or change the coincidence detection point with the sequence program. Controlling equipment according to the operating status, such as change of the coincidence detection point according to condition, is possible.

1 - 2

1.1 Features

OVERVIEW

(b) Continuous comparison function

(6) Mounting the coincidence output test function (when using the

continuous comparison function)

By using the coincidence output test function, wiring of the coincidence output terminals (EQU1, EQU2) and operations can be checked without count operation.

(7) Preset function

The present value when the preset command (Y04) is input or the preset input terminal (PRST) is turned ON can be overwritten to preset value.

Set from 1 to 16 as the coincidence detection point for each point to compare it with the present value (Only 1 point can be compared simultaneously). Whenever a coincidence is detected, the coincidence output signal is reset or the coincidence detection point is changed automatically. If this function is used when the coincidence detection point is predetermined, the sequence program can be reduced, which brings improvement in takt time.

CONFIGURATION

(8) Latch counter function

The present value when the latch counter execution command (Y07) is input or the latch counter input terminal (LATCH) is turned ON can be latched.

(9) Executing the preset function/latch counter function with external

control signal

Since the QD64D2 is independent of scan time of the programmable controller CPU, disparity in a span before executing the preset function/latch counter function can be lessen.

(10)Fuse blown at external output part is detectable.

The QD64D2 can detect fuse blown at external output part and notify it with the blown fuse detection flag (X1F) and LED display on it.

(11)Easy setting using GX Configurator-CT

The QD64D2 setting can be performed on screen by using GX Configurator-CT sold separately. Thus, the number of sequence programs results in decreasing and checking a setting status or operation status of modules easily.

• The reserved areas in the above table and areas not mentioned in the table are for system use, not for users. If written by a user, the functions of the QD64D2 are not guaranteed.

• All data in the buffer memory of the QD64D2 are initialized when the module is powered on or the programmable controller CPU is reset. To save the necessary data, use the FROM/DFRO/TO/DTO instructions in the sequence program or make setting with the utility package for writing/ reading of the buffer memory data.

• Since the buffer memory contents are automatically updated by count operation, the latest count value can be read from the buffer memory.

Coincidence output No.1 point change request (Un\G10) Coincidence output No.2 point setting (Un\G8 and 9) Coincidence output No.2 point change request (Un\G11)

• This area is used for setting the comparison point (the value used to compare with the present value) used for the coincidence output function.

• Setting procedure

1) Write any comparison point to the coincidence output No.1 point setting (Un\G 6 and 7). Setting range: -2147483648 to 2147483647

2) Write "1" (Change request) to the coincidence output No.1 point change request (Un\G10).

3) The comparison point written to the coincidence output No.1 point setting (Un\G6 and 7) becomes effective, and the coincidence output No.1 point change request (Un\G10) changes from "1" to "0" (No change request).

4) The comparison between the set comparison point and the present value is executed.

Note) If a value other than "1" is written to the coincidence output No.1 point

change request, the comparison point written to the coincidence output No.1 point setting does not become effective. For the comparison point, a value previously set in the coincidence output No.1 point setting is used.

For example, the default value of the coincidence output No.1 point setting is "0". If "10000" is written to the coincidence output No.1 point setting, the default value of "0" is used for the comparison point unless "1" is written to the coincidence output No.1 point change request.

• The above procedure is described as an example of the coincidence output No.1. To set the coincidence output No.2, replace the coincidence output No.1 setting (Un\G6 and 7) and the coincidence output No.1 point change request (Un\G10) with the coincidence output No.2 point setting (Un\G8 and 9) and the coincidence output No.2 point change request (Un\G11).

4.4 Wiring

This section describes wiring an encoder and controller to the QD64D2.

4.4.1 Wiring precautions

One of the conditions to maximize the QD64D2 functions and make the system highreliable, the external wiring has to be laid so that the QD64D2 becomes less subject to noise. This section describes the precautions on external wiring.

(1) Inputting a signal of different voltage may result in a malfunction or

mechanical failure.

(2) For 1-phase input, always perform pulse input wiring on the phase A

side.

(3) When pulse status noise is input, the QD64D2 may miscount.

(4) Take the following measures against noise for high-speed pulse input.

(a) Always use a shielded twisted pair cable and ground it on the QD64D2 side.

(b) Wire the shielded twisted pair cables so as not to be in parallel with wires causing

much noise such as power lines or I/O wires while keeping a distance of at least 150 mm (5.91 inch) between such wires. Also install the shielded twisted pair cables as short as possible.

Number Description

With the following procedures, start the coincidence detection using the value

set in the coincidence output No.1 point setting (Un\G6 and 7).

(1) Write "1000" for the coincidence output No.1 point setting (Un\G6 and 7).

(2) Write "1" (Change request) for the coincidence output No.1 point change

request (Un\G10).

(3) The setting value becomes valid when "1" (Change requet) turns to "0" (No

change request).

When the present value (Un\G12 and 13) is smaller than the coincidence output

No.1 point setting (Un\G6 and 7), the counter value small No.1 (X03) turns ON.

When outputting from the coincidence output No.1 terminal (EQU1) of external

device connector, turn ON the coincidence output enable command (Y03).

At the time, the coincidence output No.2 terminal (EQU2) is also enabled.

When the present value (Un\G12 and 13) is equal to the coincidence output

No.1 point setting (Un\G6 and 7), the counter value small No.1 (X03) turns OFF

and the counter value coincidence No.1 (X02) turns ON.

When the present value (Un\G12 and 13) is larger than the coincidence output

No.1 point setting (Un\G6 and 7), the counter value large No.1 (X01) turns ON.

The counter value coincidence No.1 (X02) remains ON until resetting it.

Turn ON the coincidence signal No.1 reset command (Y01) to reset the counter

value coincidence No.1 (X02). If the counter value coincidence No.1 (X02)

remains ON, the counter value coincidence No.1 (X02) cannot be output next

time.

FUNCTIONS

POINT

(1) At immediately after the power-on or resetting the programmable controller

CPU, the relation of the present value and the coincidence output point setting is the following: "Present value = Coincidence output point setting = 0". Therefore, the counter value coincidence (X02, X05, X12, and X15) of channels that use the coincidence output function turns ON. For channels that use the coincidence output function, always execute the following procedures from 1 to 3. For the programming method of the following procedures, refer to Section 7.3 and Section 7.4.

Procedure 1: Set the following buffer memories and make sure that the coincidence output point settings are other than "0"

POINT

• Coincidence detection interrupt occurs at the rising edge (OFF ON) of the counter value coincidence No.1 (X02) or the counter value coincidence No.2 (X05). Therefore, next interrupt request does not occur unless the counter value coincidence No.1 (X02) and the counter value coincidence No.2 (X05) are reset and turned OFF.

• When using the coincidence output function, the counter value coincidence No.1 (X02) and the counter value coincidence No.2 (X05) turns ON immediately after the power-on or resetting the programmable controller CPU; however, a coincidence detection interrupt does not occur.

5.6 Response Delay Time

In the QD64D2, a response delays due to the cause indicated in (a) and (b) below.

(a) Scan time of the sequence program

It affects the delay of I/O signal. Use the direct access input (DX) or the direct access output (DY) to minimize the delay.

(b) Control cycle (1ms) of the QD64D2

Up to 2ms (1 control cycle 2) of delay occurs until the QD64D2 reads out the output signal and buffer memory updated by the sequence program and completes processing. Update timing of the I/O signal and buffer memory varies within the range of a control cycle.

For example, the following is the maximum delay time until the QD64D2 executes the latch counter function and updates the latch count value after the latch counter execution command (Y07) is turned ON by the sequence program.

Maximum delay time [ms] = [Time of (a)] + [Maximum time of (b)]

Since the utility is add-in software for GX Developer, read "SAFETY PRECAUTIONS" and the basic operating procedures in the GX Developer Operating Manual.

(2) About installation

GX Configurator-CT is add-in software for GX Developer Version 4 or later. Therefore, GX Configurator-CT must be installed on the personal computer that has already GX Developer Version 4 or later installed.

(3) Screen error of [Intelligent function module utility]

Insufficient system resource may cause the screen to be displayed inappropriately while using the Intelligent function module utility. If this occurs, close the Intelligent function module utility, GX Developer (program, comments, etc.), and other applications, and then start GX Developer and Intelligent function module utility again.

(4) To start the [Intelligent function module utility]

(a) In GX Developer, select "QCPU (Q mode)" for [PLC series] and specify a project.

If any other than "QCPU (Q mode)" is selected for [PLC series], or if no project is specified, the [Intelligent function module utility] will not start.

(b) Multiple [Intelligent function module utility] can be started.

However, [Open parameters] and [Save parameters] operations under [Intelligent function module parameter] are allowed for one [Intelligent function module utility] only. Only the [Monitor/test] operation is allowed for the other utilities.

(5) Switching between two or more Intelligent function module utilities

When two or more Intelligent function module utility screens cannot be displayed side by side, select a screen to be displayed on the top of others using the task bar.

CONFIGURATION

For example, if multiple intelligent function modules are mounted to the remote I/O station, configure the settings in GX Configurator so that the number of parameters set for all the intelligent function modules does not exceed the limit of the remote I/O station. Calculate the total number of parameter settings separately for the initial setting and for the auto refresh setting. The number of parameters that can be set for one module in GX Configurator-CT is as shown below.

Table 6.3 Number of settable parameters per module

Target module Initial setting Auto refresh setting

QD64D2 6 (fixed) 16 (Max.)

Example) Counting the number of parameter settings in Auto refresh setting

This one row is counted as one setting. Blank rows are not counted. Count up all the setting items on this screen, and add the total to the number of settings for other intelligent function modules to get a grand total.
