1 OVERVIEW

MELSEC-Q

1.1 Features

The features of the QD62(E/D) are as follows:

(1) Counting can be performed in a wide range (The count value can be

expressed within the range between -2147483648 and 2147483647)

• A count value is stored in 32-bit signed binary.

• The number of channels is 2.

(2) The maximum counting speed can be changed

The maximum speed of the QD62D can be changed by selecting from among 500 k, 200 k, 100 k and 10 k, while that of the QD62 and QD62E can be selected from among 200 k, 100 k and 10 k. This allows an error-free count even with gradual rise/fall pulses.

(3) Pulse input can be selected

The pulse input can be selected from 1 phase multiple of 1, 1 phase multiple of 2, 2 phase multiple of 1, 2 phase multiple of 2, 2 phase multiple of 4, CW and CCW.

(4) Counter format can be selected

Either one of the following counter formats can be selected.

(a) Linear counter format

A count from -2147483648 to 2147483647 is possible and if the count exceeds the range, an overflow will be detected.

(b) Ring counter format

This type counts pulses repeatedly within the range between the ring counter upper limit and the ring counter lower limit.

(5) Coincidence output is possible

Any channel coincidence output point can be preset to compare with the present counter value to output the ON/OFF signal output, or to start an interrupt program.

(6) Selection can be made from four counter functions

One of the following four functions can be selected.

(a) Count disable function

This function stops counting pulses by inputting a signal while CH Count enable command (Y4, YC) is on.

(b) Latch counter function

This function latches the present value of the counter when the signal was input.

(c) Sampling counter function

This function counts the pulses that were input within the preset time period from the signal input.

(d) Periodic pulse counter function

This function stores the present and previous values of the counter at each preset time interval while the signal is being input.

1 OVERVIEW

MELSEC-Q

(7) Execution of the preset function and the selected counter function

with an external control signal

(a) The preset function can be performed by applying a voltage to the preset

input terminal.

(b) The function selected from counter function selection can be performed by

applying a voltage to the function start input terminal.

(8) Easy settings using the GX Configurator-CT

The use of GX Configurator-CT sold separately allows you to execute the QD62(E/D) setting on screen, resulting in reducing the number of sequence programs. Also, the use of GX Configurator-CT makes it easy to check the setting status and operating status for modules.

(9) A blown fuse in the external output section can be detected

A blown fuse in the external output section can be detected; it is notified by the input signal X and the LED display on the module.

The QD62(E/D) functions are listed below.

Values from -2147483648 to 2147483647 can be counted. If the count

exceeds the range, this function detects an overflow.

This function counts pulses repeatedly within the range between the

ring counter upper limit and the ring counter lower limit.

Compares the coincidence output point of any preset channel with the

present counter value, and outputs the ON/OFF signal.

Generates an interrupt signal to the CPU module when coincidence is

detected, and starts the interrupt program.

Stops the pulse count while the count enable command is being

executed.

Stores the present counter value at the time the counter function

selection start command signal is input in the buffer memory.

Counts the pulses that are input during the preset sampling time

period from the time the counter function selection start command is

input, and stores the count in the buffer memory.

This function stores the present and previous counter values to the

buffer memories at the preset cycle (T) while the counter function

selection start command signal is input.

The following describes the procedure prior to the QD62(E/D) operation, the name and setting of each part of the QD62(E/D), and wiring method.

The following are the precautions for handling the QD62(E/D).

(1) Do not drop the module casing or connector, or do not subject it to strong impact.

(2) Do not remove the PCB of each module from its case. Doing so may cause

breakdowns.

(3) Be careful not to let foreign particles such or wire chips get inside the module.

These may cause fire, breakdowns and malfunctions.

(4) The top surface of the module is covered with a protective film to prevent foreign

objects such as wire chips from entering the module when wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate heat ventilation.

(5) Tighten the screws such as module fixing screws within the following ranges.

If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

Screw location Tightening torque range

Module fixing screw (M3 screw)*1 0.36 to 0.48 N · m

Connector screw (M2.6 screw) 0.20 to 0.29 N · m

* 1 The module can be easily fixed onto the base unit using the hook at the top

of the module. However, it is recommended to secure the module with the module fixing screw if the module is subject to significant vibration.

(6) To mount the module on the base unit, fully insert the module fixing latch into the

fixing hole in the base unit and press the module using the hole as a fulcrum. Improper installation may result in a malfunction or breakdown of the module, or may cause the module to fall off.

4.4 Wiring

The following explains how to wire the encoder and the controller to the QD62(E/D).

4.4.1 Wiring precautions

In order to fully utilise the functions of the QD62(E/D) and ensure system reliability, external wiring having a minimum of noise effect must be provided. The precautions regarding external wiring are described below.

(1) Different terminals have been prepared for connection depending on the voltage

of the input signal. Connecting a terminal of incorrect voltage may result in 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 QD62(E/D) may miscount.

(4) Always provide the following measures against noise for high-speed pulse input:

(a) Use shielded twisted pair cables.

(b) Avoid placing the shielded twisted pair cables or input/output cables. Place

the cable at least 150 mm (5.9 inch) from such wires and perform wiring using the least distance as possible.

(c) Individually ground the shielded cables on the encoder side (relay box) with

a ground resistance of 100

or less.

(d) An example of wiring incorporating measures against noise is shown below:

MELSEC-Q

5.1.2 Setting the count method

The count method is set using the GX Developer intelligent function module switch setting. See Section 4.5 for details on the setting method.

5.1.3 Reading the present values

This section explains the methods of reading the present values stored in the buffer memory or the count values when counter function selection is executed.

(1) The present value is stored in CH

Un\G35) regardless of the counter function used. When the latch counter, the sampling counter, or the periodic pulse counter function is performed, each count value is stored in the buffer memory listed in the table below.

Description

address

CH1

CH2

(2) The present value and the counter function selection count values are stored in

the buffer memories in 32-bit signed binary. The latest count values can be read from the buffer memories because the buffer memory data are automatically updated by count operation.

POINT

When reading the present values or the counter function selection count values, use the DFRO instruction and always read values in two-word units. When reading the values in one-word units, if the count values are updated in the middle of read processing, a mismatch may occur between the data contents of the lower and higher words, possibly causing the system to read incorrect count values.

5.2 Selecting the Counter Format

Select either linear counter or ring counter with the GX Developer intelligent function module switch setting. See Section 4.5 for details on the setting method.

5.2.1 Selecting the linear counter

(1) Linear counter operation

When the linear counter is selected, the count operation is performed between

-2147483648 (minimum value) and 2147483647 (maximum value). The linear counter can be used in combination with the preset function and the coincidence output function.

(a) When the counter format is linear counter, an overflow error occurs if the

present counter value exceeds -2147483648 (minimum value) during subtraction or exceeds 2147483647 (maximum value) during addition.

(b) When an overflow error occurs, "1" is stored in CH

Overflow detection flag (Un\G8, Un\G40), the counting stops, and the present value does not change from -2147483648 or 2147483647 even if pulses are input.

(c) The overflow error can be cleared by performing the preset function.

When the preset function is performed, "0" is stored in CH

Overflow

detection flag (Un\G8, Un\G40) and the counting can be resumed.

(d) Occurrence of overflow error can be checked on the System Monitor window.

For details, refer to Section 9.1.

5 BASIC USAGE

5.2.2 Selecting the ring counter

(1) Ring counter operation

This function repeatedly counts pulses between the range specified in CH Ring counter minimum value (Un\G20, Un\G21, Un\G52, Un\G53) and CH counter maximum value (Un\G22, Un\G23, Un\G54, Un\G55). When the ring counter is being selected, an overflow error does not occur. The ring counter can be used in combination with the preset function and the coincidence output function.

Present counter value

Count down

(2) Ring counter count range

The count range of the ring counter is determined by the relationship between CH

Present value (Un\G2, Un\G3, Un\G34, Un\G35) and the ring counter lower/upper limits when CH when the preset function is performed. Normally the range used is "ring counter minimum value ≤ counter maximum value".

• For up count

When the present value reaches the ring counter maximum value, the ring counter minimum value is automatically stored as the present value.

• For down count

Even if the present value reaches the ring counter minimum value, the ring counter minimum value will be retained as is. With the next subtraction pulse,

(ring counter maximum value -1) will be stored as the present value. In counting up and down, the ring counter upper limit value is not stored in CH Present value (Un\G2, Un\G3, Un\G34, Un\G35). For example, if the count is enabled with the ring counter minimum value of 0, the ring counter maximum value of 2000 and the present value of 500, the count range and present value will change as shown in the figure below.

(a) The ring counter will operate as follows when the "present value < ring

counter minimum value" or "ring counter maximum value < present value".

• For up count Even if the present value reaches the ring counter minimum value, the ring counter minimum value will be retained as is. With the next addition pulse, (ring counter maximum value +1) will be stored as the present value.

• For down count When the present value reaches the ring counter maximum value, the ring counter minimum value is automatically stored as the present value.

In counting up and down, the ring counter upper limit value is not stored in CH

Present value (Un\G2, Un\G3, Un\G34, Un\G35). For example, if the count is enabled with the ring counter minimum value of 0, the ring counter maximum value of 2000 and the present value of 3000, the count range and present value will change as shown in the figure below.

5.3 Using the Coincidence Output Function

The coincidence output function presets any count value, compares it with the present counter value, and outputs a signal when they match. For the coincidence output, 2 points can be set for each channel. When using external output of the coincidence signal, turn on CH enable command (Y2, YA) beforehand.

(1) Coincidence Output Operation

The I/O numbers (X/Y) and the buffer memory addresses used in (1) are for coincidence output point No.1. For the I/O numbers and buffer memory addresses for coincidence output point No.2, refer to the following.

(2) Output status setting during a CPU stop error

The output status (clear/hold) can be set for the external output signal when a CPU stop error occurs. The output status is set using the GX Developer I/O assignment. See Section 4.5 for details on the I/O assignment setting method.

(3) Coincidence detection interrupt function

The coincidence detection interrupt function allows making an interrupt request to a CPU module at the time of coincidence detection to start the interrupt program. (When the CPU module is a Q00J/Q00/Q01CPU, use function version B or later.)

(a) With the MELSEC-Q series intelligent function module, each module can

have up to 16 points of interruption factors (SI). The QD62 (E/D) has 4 points of interrupt factors corresponding to the coincidence outputs shown below.

4) Intelli. module side "Start SI No." Set the start interrupt factor (SI) No. of the QD62(E/D). Setting range: 0 to 3

The following example shows SI 0 to 3 of the QD62(E/D) installed in the slot where the start I/O is 20 being assigned to interrupt pointers I50 to I53.

(c) The following two methods are available for using only specific SI numbers:

1) Method using the parameter interrupt pointer setting The interruption factors are used only for the start SI number and the additional number of pointers, only which are specified in the "Intelligent function module interrupt point setting" window. For example, if the start SI number is set as 1 and the number of pointers is set as 2, only SI 1 and 2 are used. Also, the interrupt function cannot be used when the parameter interrupt pointer setting has not been set.

2) Method using the IMASK instruction from the sequence program When the IMASK instruction is used, interrupt program execution enable/disable (interrupt mask) can be set for each interrupt pointer number. For details on the IMASK instruction, refer to the MELSEC-Q/L Programming Manual (Common Instruction).

POINT

A coincidence detection interrupt occurs when the counter value coincidence signal rises (off to on). Thus, the next interrupt request does not occur unless the coincidence signal is reset and the counter value coincidence signal is turned OFF.

5.4 Using the Preset Function

The preset function rewrites the present counter value to any numeric value called the preset value. The preset function can be used when starting the pulse count from the preset value.

This function counts the input pulses during the preset sampling period since the time the counter function selection start command was entered.

This function stores the present value and previous value for each preset periodic time while the counter function selection start command is being entered.

POINT

(1) Change the counter function while CH Counter function selection start

The present value and the counter function selection count values are stored in the buffer memories in 32-bit signed binary. Also, since the contents of the buffer memory are automatically updated by the count operation, the latest count values can be read from the buffer memory.

POINT

(1) When reading the present and counter function selection count values, use the

DFRO instruction and always read values in two-word units. When reading values in one-word units, if the count values are updated in the middle of read processing, a mismatch may occur between the data contents of the lower and higher words, possibly causing the system to read incorrect count values.

Note the following when reading CH Periodic pulse count previous value (Un\G16, Un\G17, Un\G48, Un\G49) and CH (Un\G18, Un\G19, Un\G50, Un\G51). (1) When reading values using a sequence program, use the DFRO instruction or

the BMOV instruction and read values in four-word units. [Program example]

Depending on the relation between the update timings of the previous and present values inside the module and the read timing in the sequence program, the previous value and the present value may be the same. In that case, read values gain. (See Section 8.1.2, Section 8.2.2.)

(2) When reading values using the auto refresh setting, only the value in the

device to where the present value is written may change depending on the relation between the update timings of the previous and present values inside the module and the auto refresh timing. In that case, read values using a sequence program. For details, see (1) above.

The following explains an example to change settings for the selected test operation to the following:

• Counter function selection setting : Sampling counter function

• Counter function selection start command (Y06) : ON

• Sampling/periodic setting [unit: 10 ms] : 1000 ms

(1) Set "Sampling counter function" in the setting value field for CH

function selection setting.

(2) Set "ON" in the setting value field for CH

command (Y06).

(3) Click the setting value field for CH

(4) After entering the sampling time, press the Enter

At this point, nothing has been written to the QD62 (E/D).

(5) Select the setting value fields that were specified in steps 1 to 4 while holding

down the Ctrl

This chapter describes programs of the QD62 (E/D). When applying any of the program examples introduced in this chapter to the actual system, verify the applicability and confirm that no problem occurs in the system control.

8.1 Using Programs in Normal System Configuration

This section describes program examples based on the following system configuration and conditions.

(1) System configuration

QX10 (X10 to X1F)

QY10 (Y20 to Y2F)

(X/Y0 to X/YF)

QD62

(2) Setting conditions of the intelligent function module switch

Set the pulse input mode, counting speed setting, and counter format with the intelligent function module switch on GX Developer. (See Section 4.5.)

Channel Pulse input mode Counting speed setting Counter format

CH1 2-phase multiple of 1 200 kPPS User setting

(3) Program conditions

8 - 1 8 - 1

This program uses QD62 to perform counting with the conditions listed below.

Item Setting value

Preset value 2500

Coincidence output point No. 1 1000

Ring counter minimum value 1 –5000

Ring counter maximum value 1 5000

Sampling time setting 2 10000 ms

Periodic pulse time setting 3 5000 ms

1 Set only when a ring counter function is used 2 Set only when the sampling counter function is used 3 Set only when the periodic pulse counter function is used

POINT

Programs that were used in earlier products such as A1SD62(E/D/D-S1) cannot be used because the I/O signals and the buffer memory configuration of these products differ from those of QD62(E/D). The conventional dedicated instructions cannot be used.
