CAUTION
Use the programmable controller in an environment that meets the general specifications in the user’s manual for the CPU module used. Failure to do so may result in electric shock, fire, or damage to or deterioration of the product.
To mount the module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw. Tighten the screw within the specified torque range. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in damage to the product.
Do not directly touch any conductive part or electronic component of the module. This may cause the module to malfunction or fail.
[Wiring Precautions]
!
CAUTION
Connectors for external connection must be crimped or pressed with the tool specified by the manufacturer, or must be correctly soldered. Connect the connector part to the module securely.
Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.
A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation.
Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.
A - 2 A - 2
[Wiring Precautions]
!
CAUTION
When disconnecting the cable with the connector from the module, do not pull the cable by the cable part, but hold the connector to the module by hand and pull it out to remove the cable. Failure to do so may result in damage to the module or cable or malfunction due to poor contact.
Ground the shielded cable on the encoder (relay box) side. Failure to do so may result in malfunction.
Check the rated voltage and terminal layout before wiring to the module, and connect the cables correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or failure.
[Startup and Maintenance Precautions]
!
CAUTION
Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury or a fire.
Shut off the external power supply for the system in all phases before cleaning the module or retightening the terminal screws or module fixing screws. Failure to do so may result in electric shock.
After the first use of the product, do not mount/remove the module to/from the base unit more than 50 times (IEC 61131-2 compliant) respectively. Exceeding the limit of 50 times may cause malfunction.
Do not touch the terminals while the power is on. Doing so may cause malfunction.
Shut off the external power supply for the system in all phases before cleaning the module or
retightening the terminal screws or module fixing screws. Failure to do so may result in electric shock. Undertightening the terminal screws can cause short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Before handling the module, touch a grounded metal object to discharge the static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

1 OVERVIEW
MELSEC-Q

1.1 Features

The features of the QD62(ED) 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)
The count values are stored as 2-channel 32-bit signed binary codes.
(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 200k, 100k and 10k. 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
Counting is performed repeatedly between the ring counter maximum value and minimum value.
(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) Latch counter function
This function latches the present value of the counter when the signal was input.
(b) Sampling counter function
This function counts the pulses that were input within the preset time period from the signal input.
(c) 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.
(d) Disable count function
This function inputs a signal while executing the count enable command to stop pulse counting.

1 OVERVIEW
MELSEC-Q
(7) The preset function/counter selection function can be executed
using an external control signal
By applying voltage to the preset input terminal/function start input terminal of an external terminal, preset function/counter function selection can be executed.
(8) Easy settings using the GX Configurator-CT
The use of GX Configurator-CT sold separately allows you to execute the high-speed counter module 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.
Repeatedly executes counting between the ring counter maximum and
minimum values.
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 programmable controller CPU
when coincidence is detected, and starts the interrupt program.
Rewrites the present counter value to any numeric value.
Performs preset using the sequence program or external preset input.
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.
While the counter function selection start command signal is being
input, stores the present value in the buffer memory at preset interval.

Turns ON when the count preparation for QD62(E/D) is completed at the time of programmable controller CPU power on or reset operation, and count processing is performed. When Module ready (X00) is OFF, count processing is not performed.
Turns ON when the present value (CH1: 2H to 3H, CH2: 22H to 23H) > coincidence output point No. 1 setting (CH1: 4H to 5H, CH2: 24H to 25H). Turns OFF when the present value setting.
Turns ON when the present value = coincidence output point No.1 setting and the present value is latched. Turns OFF with the coincidence signal No.1 reset command (Y00/Y08). The counter value coincidence (point No.1) turns ON immediately after power-ON or reset of the programmable controller CPU, since the present value and coincidence output point No.1 are all '0'.
Turns ON when the present value < coincidence output point No.1 setting. Turns OFF when the present value setting.
Turns ON with a preset command signal from the external input terminal, and the request is latched. Turns OFF with the external preset detection reset signal (Y05/Y0D).
Turns ON when the present value > coincidence output point No.2 setting (CH1: 6H to 7H, CH2: 26H to 27H). Turns OFF when the present value setting.
Turns ON when the present value = coincidence output point No.2 setting and the present value is latched. Turns OFF with the coincidence signal No.2 reset command (Y07/Y0F). The counter value coincidence (point No.2) turns ON immediately after power-ON or reset of the programmable controller CPU, since the present value and coincidence output point No.2 are all '0'.
Turns ON when the present value < coincidence output point No.2 setting. Turns OFF when the present value coincidence output point No.2 setting.

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) Provide the following measures against noise for high-speed pulse input:
(a) Always use a shielded twisted pair cable and provide grounding.
(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.
(5) An example of wiring incorporating measures against noise is shown below:

MELSEC-Q
Inverter
Terminal block
Provide a clearance of 150 mm (5.9 inch) or more from I/O wires to high voltage equipment such as inverters. (Also exercise caution for wiring inside the panel.)

• Grounding the shielded twisted pair cable is performed on the encoder side (relay box). (This example
shows connection with 24 V sink load.
Do not enclose solenoids and inductive loads together within the same metal conduit. If a sufficient distance cannot be secured to isolate ducts and other wires from a high­voltage line, use CVVS or other shielded wire for the high-voltage line.
The distance between the encoder and relay box must be short. Allowing a long distance between

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) When any function is used, the present value is stored into the buffer memory for
storing the present value. When the latch counter, sampling counter or periodic pulse counter function is executed, the count value is stored into the buffer memory for storing the counter function selection count value at the addresses shown in the table below, aside from the buffer memory for storing the present value.

(2) Both the present values and counter function selection count values are stored in
the buffer memory as 32-bit signed binary values. In addition, 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
When reading the present values or the counter function selection count values, use the DFRO command 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.

(2) Overflow error
(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 the buffer memory overflow
detection flag (addresses CH1: 8
H, CH2: 28H) and the count stops. Even if a
pulse is input, the present value will not change from –2147483648 or
2147483647.
(c) Performing a preset will cancel the overflow error.
When a preset is performed, 0 is stored in the buffer memory overflow detection flag and the count resumes.
(d) When an overflow error occurs, a generated module error can be viewed on
the system monitor by clicking "Diagnosis" - "System monitor" menu in the GX Developer.
5 - 4 5 - 4
5 BASIC USAGE

5.2.2 Selecting the ring counter

(1) Ring counter operation
When the ring counter is selected, the count operation is performed repeatedly between the ring counter minimum value (addresses CH1: 14 to 35
H) and maximum value (addresses CH1: 16H to 17H, CH2: 36H to 37H) that
were set arbitrarily in the buffer memory. 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
Subtraction
(2) Ring counter count range
The count range for the ring counter is determined by the relationship between the present values in the buffer memory (addresses CH1: 2 23
H) at the time the count enable command {Y04 (Y0C)} turns ON or a preset is
executed and the ring counter minimum value/maximum value. 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.
Whether during up count or down count, the ring counter maximum value will not be stored in the buffer memory for storing the present values. 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.
Whether during up count or down count, the ring counter maximum value will not be stored in the buffer memory for storing the present values. 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.

maximum value", the count range will cover any value that can be expressed in 32-bit signed binary values (-2147483648 to 2147483647), regardless of the present value.
POINT
(1) When the count enable command {Y04(Y0C)} is ON, the set values for the
buffer memory will not change even if values are written as the minimum value and maximum value of the ring counter. To change the ring counter maximum and minimum value settings, first turn the count enable command OFF.
(2) When the count range is to be changed using preset, always change it after
first turning the count enable command {Y04(Y0C)} OFF.

(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 programmable controller CPU at the time of coincidence detection to start the interrupt program. (When the programmable controller CPU 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.

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 command from the sequence program When the IMASK command is used, interrupt program execution enable/disable (interrupt mask) can be set for each interrupt pointer number. Refer to the QCPU (Q Mode)/QnACPU Programming Manual for details on the IMASK command.

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. The preset function has two preset methods: preset using a sequence program and preset using an external control signal.

6.1 Selecting the Counter Function

By selecting the counter function with the counter function selection setting, the disable count function, latch counter function, sampling counter function and periodic pulse counter function can be used. The counter function selection can be executed by writing the data shown in the table below into the counter function selection setting buffer memory (address 9 by using the counter function selection start command (voltage applied to the function start input terminal or turning Y06 (Y0E) ON using the sequence program). Also, for the counter function selection, only one of the following four functions can be used.
Counter function selection Set value Remarks
Disable count function 0 Initial value (default) Latch counter function 1
Sampling counter function 2
Periodic pulse counter function 3
(1) Disable count function
This function stops the count while the counter function selection start command is being entered when the count enable command (Y04 (Y0C)) is ON.
(2) Latch counter function
This function latches the present value at the time the counter function selection start command was entered to the latch count value (addresses C to 2D
H).
(3) Sampling counter function
This function counts the input pulses during the preset sampling period since the time the counter function selection start command was entered.
(4) Periodic pulse counter function
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 the counter function selection start
command is OFF.
(2) The counter function selection can be executed either by turning Y06 (Y0E) ON
or applying voltage to the function start input terminal. Also, the signal that was entered first takes precedence.
(3) Time settings for the sampling counter function and the periodic pulse counter
function are performed by writing data in a range from 1 to 65535 into the sampling/periodic setting buffer memory {address A (Example) When 420 is specified in the sampling/periodic time setting buffer memory
Setting time = 420

6.1.1 Reading the counter function selection count value

MELSEC-Q
6
The counter function selection count values are stored when the counter function selection is executed. The count values when the latch counter, sampling counter and periodic pulse counter functions are executed are stored in the counter function selection count value storage buffer memory at the addresses shown in the table below.
Contents
Buffer

value
The present values and counter function selection count values are stored as 32-bit signed binary values in the buffer memory. 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 command 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.

(2) Although the latch count value and present periodic pulse count value are
stored in different addresses, the same values are always stored (updated at the same time). Thus, when the latch counter function or periodic pulse counter function is executed, the present periodic pulse count value and latch count value do not retain their previous values.

6.1.2 Count error

With the counter function selection, an error occurs in the count when it is executed using an external input (voltage applied to the function start input terminal) or by a sequence program (counter function selection start command ON). The following explains how to calculate the count error.
(1) Count error (maximum) due to input response delay when using an
external input
(2) Count error (maximum) when the counter function selection is
executed by a sequence program
(3) Count error (maximum) due to the internal clock when executing

This chapter describes programs of the QD72(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)

(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.
