WARNING
Do not attempt to take any Unit apart or touch the inside of any Unit while the
power is being supplied. Doing so may result in electric shock.
Do not touch any of the terminals or terminal blocks while the power is being
supplied. Doing so may result in electric shock.
Provide safety measures in external circuits (i.e., not in the Programmable
Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the Programmable Controller or
another external factor affecting the operation of the Programmable Controller. “Programmable Controller” indicates the CPU Unit and all other Units and
is abbreviated “PLC” in this manual. Not doing so may result in serious accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
Unexpected operation, however, may still occur for errors in the I/O control
section, errors in I/O memory, and other errors that cannot be detected by
the self-diagnosis function. As a countermeasure for all such errors, external safety measures must be provided to ensure safety in the system.
• The PLC outputs may remain ON or OFF due to deposition or burning of
the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to
ensure safety in the system.
• Provide measures in the computer system and programming to ensure
safety in the overall system even if communications errors or malfunctions
occur in data link communications or remote I/O communications.
Confirm safety before transferring data files stored in the file memory (Memory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a
peripheral tool. Otherwise, the devices connected to the output unit may malfunction regardless of the operation mode of the CPU Unit.
Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes. Serious accidents
may result from abnormal operation if proper measures are not provided.
CJ2M CPU Unit Pulse I/O Module User’s Manual

Caution
Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be
readable.
Confirm safety at the destination node before transferring a program, PLC
Setup, I/O tables, I/O memory contents, or parameters to another node or
changing contents of the any of these items. Transferring or changing data
can result in unexpected system operation.
The CJ2 CPU Units automatically back up the user program and parameter
data to flash memory when these are written to the CPU Unit. I/O memory
including the DM, EM, and Holding Areas), however, is not written to flash
memory.
The DM, EM, and Holding Areas can be held during power interruptions with
a battery. If there is a battery error, the contents of these areas may not be
accurate after a power interruption. If the contents of the DM, EM, and Holding Areas are used to control external outputs, prevent inappropriate outputs
from being made whenever the Battery Error Flag (A402.04) is ON.
Tighten the terminal screws on the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction.
Do not touch the Power Supply Unit when power is being supplied or immediately after the power supply is turned OFF. The Power Supply Unit will be hot
and you may be burned.
When connecting a personal computer or other peripheral device to a PLC to
which a non-insulated Power Supply Unit (CJ1W-PD022) is mounted, either
ground the 0 V side of the external power supply or do not ground the external power supply at all ground. A short-circuit will occur in the external power
supply if incorrect grounding methods are used. Never ground the 24 V side,
as shown below.

Application Precautions
Observe the following precautions when using a CJ-series PLC.
z Power Supply
• Always use the power supply voltages specified in the user’s manuals. An incorrect voltage may
result in malfunction or burning.
• Exceeding the capacity of the Power Supply Unit may prevent the CPU Unit or other Units from
starting.
• Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction.
• Always turn OFF the power supply to the PLC before attempting any of the following. Not turning
OFF the power supply may result in malfunction or electric shock.
• Mounting or dismounting Power Supply Units, I/O Units, CPU Units, Option Boards, Pulse I/O
Modules or any other Units.
• Assembling the Units.
• Setting DIP switches or rotary switches.
• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
• When cross-wiring terminals, the total current for all the terminal will flow in the wire. Make sure
that the current capacity of the wire is sufficient.
• Observe the following precautions when using a Power Supply Unit that supports the Replacement Notification Function.
• Replace the Power Supply Unit within six months if the display on the front of the Power Supply Unit alternates between 0.0 and A02, or if the alarm output automatically turns OFF.
• Keep the alarm output cable separated from power line and high-voltage lines.
• Do not apply a voltage or connect a load exceeding the specifications to the alarm output.
• When storing the Power Supply Unit for more than three months, store it at −20 to 30°C and
25% to 70% humidity to preserve the Replacement Notification Function.
• If the Power Supply Unit is not installed properly, heat buildup may cause the replacement notification signal to appear at the wrong time or may cause interior elements to deteriorate or
become damaged. Use only the standard installation method.
• Do not touch the terminals on the Power Supply Unit immediately after turning OFF the power
supply. Residual voltage may cause electrical shock.
• Observe the following precautions to prevent failure due to difference in electrical potential if the
computer is connected to the PLC.
• Before connecting a laptop computer to the PLC, disconnect the power supply plug of the
computer from the AC outlet. Residual current in the AC adaptor may cause difference in electrical potential to occur between the computer and the PLC. After you connect the computer
and PLC, supply the power again from the AC adaptor.
• If the computer has an FG terminal, make the connections so that it has the same electrical
potential as the FG (GR) terminal on the PLC.
• If the computer is grounded to a separate location, difference in electrical potential may occur
depending on the grounding conditions.
z Installation
• Do not install the PLC near sources of strong high-frequency noise.
• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up. Not doing so may result in malfunction or damage.
CJ2M CPU Unit Pulse I/O Module User’s Manual
21
• Be sure that the terminal blocks, connectors, Memory Cards, Option Boards, Pulse I/O Modules,
expansion cables, and other items with locking devices are properly locked into place.
• The sliders on the tops and bottoms of the Power Supply Unit, CPU Unit, I/O Units, Special I/O
Units, CPU Bus Units, and Pulse I/O Modules must be completely locked (until they click into
place) after connecting to adjacent Units. It may not be possible to achieve proper functionality if
the sliders are not locked.
z Wiring
• Follow the instructions in this manual to correctly perform wiring.
• Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring
may result in burning.
• Be sure that all terminal screws, and cable connector screws are tightened to the torque specified
in the relevant manuals. Incorrect tightening torque may result in malfunction.
• Mount terminal blocks and connectors only after checking the mounting location carefully.
• Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if
foreign matter enters the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the
label attached may result in malfunction.
• Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning.
• Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may
result in burning.
• Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground
of 100 Ω or less may result in electric shock.
A ground of 100 Ω or less must be installed when shorting the GR and LG terminals on the Power
Supply Unit.
• Do not apply voltages or connect loads to the Output Units in excess of the maximum switching
capacity. Excess voltage or loads may result in burning.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may
break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.
• Do not use commercially available RS-232C personal computer cables. Always use the special
cables listed in this manual or make cables according to manual specifications. Using commercially available cables may damage the external devices or CPU Unit.
• Never connect pin 6 (5-V power supply) on the RS-232C port on the CPU Unit to any device other
than an NT-AL001 Link Adapter, CJ1W-CIF11 Converter, and Programmable Terminals (NV3WM@20L). The external device or the CPU Unit may be damaged.
z Handling
• The Power Supply Unit may possibly be damaged if the entire voltage for a dielectric strength test
is applied or shut OFF suddenly using a switch. Use a variable resistor to gradually increase and
decrease the voltage.
• Separate the line ground terminal (LG) from the functional ground terminal (GR) on the Power
Supply Unit before performing withstand voltage tests or insulation resistance tests. Not doing so
may result in burning.
• Make sure that the DIP switches and DM Area are set correctly before starting operation.
• After replacing the CPU Unit, a Special I/O Unit, or a CPU Bus Unit, make sure that the required
data for the DM Area, Holding Area, and other memory areas has been transferred to the new
Unit before restarting operation.
• Confirm that no adverse effect will occur in the system before attempting any of the following. Not
doing so may result in an unexpected operation.
• Changing the operation mode of the PLC (including the setting of the startup operation mode).
• Force-setting/force-resetting any bit in memory.
22
CJ2M CPU Unit Pulse I/O Module User’s Manual
• Changing the present value of any word or any set value in memory.
• Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
• Do not drop the PLC or subject abnormal vibration or shock to it.
• The life of the battery will be reduced if the PLC is left for a period of time without a battery
installed and without power supply, and then a battery is installed without turning ON the power
supply.
• Replace the battery as soon as a battery error occurs or as soon as the specified battery backup
time expires. Be sure to install a replacement battery within two years of the production date
shown on the battery's label.
• Before replacing the battery, turn ON power for at least 5 minutes before starting the replacement
procedure and complete replacing the battery within 5 minutes of turning OFF the power supply.
Memory contents may be corrupted if this precaution is not obeyed.
• If the Battery Error Flag is used in programming the application, confirm system safety even if the
system detects a battery error before you replace the battery while the power is ON.
• Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not
subject the battery to strong shocks. Doing any of these may result in leakage, rupture, heat generation, or ignition of the battery. Dispose of any battery that has been dropped on the floor or otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they
are used.
• UL standards require that only an experienced engineer can replace the battery. Make sure that
an experienced engineer is in charge of battery replacement. Follow the procedure for battery
replacement given in this manual.
• Dispose of the product and batteries according to local ordinances as they apply.
• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain
their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM
mode. Make sure that the external loads will not produce dangerous conditions when this occurs.
(When operation stops for a fatal error, including those produced with the FALS(007) instruction,
all outputs from Output Unit will be turned OFF and only the internal output status will be maintained.)
• Unexpected operation may result if inappropriate data link tables or parameters are set. Even if
appropriate data link tables and parameters have been set, confirm that the controlled system will
not be adversely affected before starting or stopping data links.
• Write programs so that any data that is received for data link communications is used only if there
are no errors in the CPU Units that are the sources of the data. Use the CPU Unit error information in the status flags to check for errors in the source CPU Units. If there are errors in source
CPU Units, they may send incorrect data.
• All CPU Bus Units will be restarted when routing tables are transferred from a Programming
Device to the CPU Unit. Restarting these Units is required to read and enable the new routing
tables. Confirm that the system will not be adversely affected before transferring the routing
tables.
• Tag data links will stop between related nodes while tag data link parameters are being transferred during PLC operation. Confirm that the system will not be adversely affected before transferring the tag data link parameters.
• If there is interference with network communications, output status will depend on the devices that
are being used. When using devices with outputs, confirm the operation that will occur when there
is interference with communications, and implement safety measures as required.
CJ2M CPU Unit Pulse I/O Module User’s Manual
23
• When creating an AUTOEXEC.IOM file from a Programming Device (a Programming Console or
the CX-Programmer) to automatically transfer data at startup, set the first write address to
D20000 and be sure that the size of data written does not exceed the size of the DM Area. When
the data file is read from the Memory Card at startup, data will be written in the CPU Unit starting
at D20000 even if another address was set when the AUTOEXEC.IOM file was created. Also, if
the DM Area is exceeded (which is possible when the CX-Programmer is used), the remaining
data will be written to the EM Area.
• The user program and parameter area data in the CJ2 CPU Units are backed up in the built-in
flash memory. The BKUP indicator will light on the front of the CPU Unit when the backup operation is in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator is
lit. The data will not be backed up if power is turned OFF.
• Check the user program and Unit parameter settings for proper execution before actually running
them on the Unit. Not checking the program and parameter settings may result in an unexpected
operation.
• When setting a Special I/O Unit or CPU Bus Unit in the I/O tables, carefully check the safety of the
devices at the connection target before restarting the Unit.
• Do not turn OFF the power supply to the PLC when reading or writing a Memory Card. Also, do
not remove the Memory Card when the BUSY indicator is lit. Doing so may make the Memory
Card unusable.
To remove a Memory Card, first press the memory card power supply switch and then wait for the
BUSY indicator to go out before removing the Memory Card.
• When restoring data, carefully check that the selected data is the correct data to be restored
before executing the restore operation. Depending on the contents of the selected data, the control system may operate unexpectedly after the data is restored.
• Some Special I/O Units and CPU Bus Units operate with parameters stored in the CPU Unit (e.g.,
words allocated in DM Area, data link tables, or Ethernet settings). Information on restrictions will
be displayed in the Information Area in the PLC Backup Tool if there are any restrictions for the
selected CPU Bus Unit or Special I/O Unit. Check the restrictions, and then be sure to select both
the CPU Unit and the CPU Bus Unit or Special I/O Unit when backing up or restoring data. The
control system may operate unexpectedly if the equipment is started with the data backed up or
restored without selecting both Units.
• Information on restrictions will be displayed in the Information Area in the PLC Backup Tool if the
data to be stored includes a Unit that has restrictions on backup. Check the information on restrictions and take the required countermeasures. The control system may operate unexpectedly
when the equipment is operated after the data is restored
• Before restoring data during PLC operation, be sure that there will be no problem if PLC operation
stops. If the PLC stops at an unexpected time, the control system may operate unexpectedly.
• Be sure to turn the PLC power supply OFF and then back ON after restoring data. If the power is
not reset, the system may not be updated with the restored data, and the control system may
operate unexpectedly.
• Data on forced status can be backed up but it cannot be restored. Perform the procedure to forceset or force-reset bits from the CX-Programmer as required before starting operation after restoring data that includes forced status. Depending on the difference in the forced status, the control
system may operate unexpectedly.
• If a symbol or memory address (only symbols are allowed for ST programming) is specified for the
suffix of an array variable in ladder or ST programming, be sure that the specified element number
does not exceed the maximum memory area range.
Specifying an element number that exceeds the maximum range of the memory area specified for
the symbol will result accessing data in a different memory area, and may result in unexpected
operation.
• If a symbol or address is specified for an offset in a ladder diagram, program so that the memory
area of the start address is not exceeded when the offset is specified indirectly using a word
address or symbol.
If an indirect specification causes the address to exceed the area of the start address, the system
will access data in other area, and unexpected operation may occur.

CJ2M CPU Unit Pulse I/O Module User’s Manual
z External Circuits
• Always turn ON power to the PLC before turning ON power to the control system. If the PLC
power supply is turned ON after the control power supply, temporary errors may result in control
system signals because the output terminals on DC Output Units and other Units will momentarily
turn ON when power is turned ON to the PLC.
• Install external breakers and take other safety measures against short-circuiting in external wiring.
Insufficient safety measures against short-circuiting may result in burning.

Overview of the Functions of CJ2M
Pulse I/O
The following functions of the pulse I/O of the CJ2M can be used by installing a Pulse I/O Module.
Select which function to use for each input and output in the PLC Setup.
Functions of Normal I/O
The inputs and outputs on the Pulse I/O Module can be used as normal inputs and normal outputs.
(Each Pulse I/O Module provides up to 10 inputs and 6 outputs.) The input time constant can be set to
0 ms (no filter), 0.5 ms, 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, or 32 ms. The same setting is used for all 20
inputs. Chattering and the effects of external noise can be reduced by increasing the input time constant.
Quick-response Inputs
By setting an input on the Pulse I/O Module to quick-response input operation, inputs with signal widths
as small as 30 µs can be read with certainty regardless of the cycle time. Up to four quick-response
inputs can be used for each Pulse I/O Module (eight for the entire CJ2M PLC).
Interrupt Inputs
An interrupt task can be started when an input on the Pulse I/O Module turns ON or OFF (Direct Mode).
Alternatively, the rising or falling edge of the inputs can be counted. When the count reaches a specified
value, an interrupt task can be started. This is called Counter Mode. Up to four interrupt inputs can be
used for each Pulse I/O Module (eight for the entire CJ2M PLC).
High-speed Counters
A rotary encoder can be connected to the Pulse I/O Module input to accept differential phase or singlephase high-speed pulse counter inputs.
High-speed counter inputs (differential phase: 50 kHz, single-phase: 100 kHz) for up to 2 axes can be
used for each Pulse I/O Module (up to 4 axes for the entire CJ2M PLC).
z Use the Linear Mode or Ring Mode for the Counting Mode
The maximum value of the ring counter can be changed during operation using the MODE CONTROL (INI(880)) instruction.
z Start Interrupt Tasks Using Target Value Comparison or Range Comparison
for High-speed Processing
Interrupt tasks can be started when the PV reaches a target value for target value comparison, or
when it enters a specified range for range comparison.
z Frequency Measurement
The input pulse frequency can be measured by executing the HIGH-SPEED COUNTER PV READ
(PRV(881)) instruction. (Applicable only to high-speed counter 0.) It is possible to convert the frequency to a rotational speed by executing the COUNTER FREQUENCY CONVERT (PRV2(883))
instruction.
1-4
CJ2M CPU Unit Pulse I/O Module User’s Manual
1 Overview
The High-speed Counter Gate Bit can be turned ON/OFF from the ladder program to select whether
the high-speed counter PVs will be maintained or refreshed.
Pulse Outputs
Fixed duty ratio pulse outputs can be output from the Pulse I/O Module outputs and used to perform
position or speed control with a Servo Drive or a stepping motor that accepts pulse inputs. Each Pulse
I/O Module provides 100-kHz pulse outputs for up to 2 axes (up to 4 axes for entire CJ2M PLC).
z Trapezoidal or S-curve Acceleration and Deceleration for Positioning
Trapezoidal or S-curve acceleration and deceleration can be used for position control using the
PULSE OUTPUT (PLS2(887)) instruction.
z Triangular Control for Pulse Outputs
If the target frequency cannot be reached when the setting is changed with a PLS2(887) or
ACC(888) instruction, triangular control will be performed. If the target position is exceeded using
the specified deceleration ratio, the deceleration ratio will be automatically corrected.
z Jogging Can Be Performed
Jogging can be performed by executing the SPED(885) or ACC(888) instruction.
z Pulse Output Frequency Tracing
Changes in the pulse output frequency can be checked graphically by using the CX-Programmer's
Data Trace Window.
z Easy Interrupt Feeding
An interrupt input can be used as a trigger to switch from speed control to position control and output the specified number of pulses, then decelerate to a stop using the INTERRUPT FEEDING
(IFEED(892)) instruction.
z Origin Searches and Origin Returns Can Be Performed Using the ORIGIN
SEARCH Instruction
An accurate origin search combining all I/O signals can be executed with a single instruction. It is
also possible to move directly to an established origin using the ORIGIN SEARCH (ORG(889))
instruction. It is also possible to perform origin returns by directly moving to a defined origin.
The origin search and origin return settings can be changed during operation using the MODE
CONTROL (INI(880)) instruction.
PWM Outputs
Lighting and power control can be performed by outputting variable duty ratio pulse (PWM) output signals from the outputs of the Pulse I/O Module.
Up to two PWM outputs can be used for each Pulse I/O Module (four for the entire CJ2M PLC).

Function
The status of input signals for normal I/O is read and
stored in I/O memory during the I/O refresh period.
The input signal triggers an interrupt task when it
turns ON or OFF.
The number of ON transitions or OFF transitions in
the input signal is counted and an interrupt task is
started when the specified count is reached.
High-speed counter inputs can be used to count
high-speed pulse signals. Interrupt tasks can also
be started.
Outputs according to the content of the I/O memory
and refresh timing.
The specified number of pulses are output at a fixed
duty ratio (50%) at the specified frequency.
Pulse are output at the specified duty ratio.
Defines the machine origin by actually executing
pulse output based on the pattern specified in the
origin search parameters, using the origin proximity
input and origin input signals as conditions. (Inputs
and outputs are used in combination.)

Allocating I/O Functions
Specifying the Functions to Use
Each of the Pulse I/O Module inputs and outputs are used for one of the I/O functions.
Some I/O terminals may support more than one function. However, only one function can be
assigned to each terminal. Specify the input functions in the PLC Setup from the CX-Programmer,
and specify the output functions in PLC Setup and programming instructions.
Multiple terminals are sometimes used in combination depending on the function, so some functions
cannot be combined. Allocate functions to be used to terminals in the CX-Programmer's PLC Setup.
The CX-Programmer automatically displays the combination of terminals that can be selected so
that there is no need to be concerned about allocating more than one function to the same terminal.
To see which functions can be allocated to which I/O terminals, refer to 2-2-3 Allocating Functions to
Input Terminals and 2-2-4 Allocating Functions to Output Terminals.
2-2-2
Selecting Functions in the PLC Setup
• Inputs can be selected on the I/O Module Tab Page.
Click the Set Button in the Interrupt Inputs and Quick-response Inputs Area to display a dialog box to
allocate functions to interrupt inputs and quick-response inputs.
The order of preference for allocating functions to inputs is as follows:
Origin Search > High-speed Counter (Phase Z/Reset) > Normal Inputs, Interrupt Inputs, and Quickresponse Inputs

Prohibition of Duplicated Use of Input Terminal Numbers
The bits 00 to 09 of CIO 2960 and CIO 2962 are used for interrupt inputs, quick-response inputs, highspeed counters, origin searches, and normal inputs. The same input terminal can be used for only one
of these functions. For example, if quick-response input 2 is used, then input terminal 02 cannot be
used for normal input 2, interrupt input 2, counter 1 phase Z/reset, or pulse output 1 origin input signal.

Additional Information
For the counter inputs, it is necessary to check the factors that can affect the pulses, such as the type of output driver
in the encoder, cable length, and count pulse frequency. When counting pulses that exceed 60 kHz, we recommend
using an encoder with a line-driver output. To ensure that pulses can be counted stably, use a shielded twisted-pair
cable and keep the cable to 3 m or less in length.

Wiring
There are the following three methods for wiring a Pulse I/O Module.
• Using Connector-Terminal Block Conversion Units
Connector-Terminal Block Conversion Units are used when using normal I/O, quick-response
inputs, interrupt inputs, PWM outputs, or pulse outputs to stepping motors or other manufacturer's
Servo Drives.
• Using Servo Relay Units
Servo Relay Units are used when using OMRON's Servo Drives.
• Directly Connecting a Self-made Cable with a Connector
A self-made cable with a Connector can be used to directly connect the I/O.

CJ2M CPU Unit Pulse I/O Module User’s Manual
3 I/O Specifications and Wiring for Pulse I/O Modules
Precautions for Safe Use
• Never apply a voltage that exceeds the input voltage of the I/O circuits or the maximum switching capacity of the output circuits.
• When the power supply has positive and negative terminals, always wire them correctly.
• Use reinforced insulation or double insulation for the DC power supplies used for I/O to comply
with the EC Low Voltage Directive.
• Always double-check the connector wiring before turning ON the power.
• Do not pull on the cable. Doing so will damage the cable.
• The connector pin allocation of the CJ1W-ID232/262 and OD233/263 connectors is not compatible. The Unit's internal circuits may be damaged if one of these connectors is connected.
• Do not connect a 24-VDC output device to a line driver input. Doing so may damage the internal circuits.
• Do not connect a line driver output device to the DC input. Doing so will not damage the internal circuits, but the input will not be recognized.
A special OMRON Connecting Cable with a connector is used to connect the Connector-Terminal
Block Conversion Unit.

Overview
The status of input signals for normal inputs are read and stored in I/O memory during the I/O refresh
period in the same way as it is for Input Units. The input time constant (ON/OFF response time) can
also be set.
Bits 00 to 09 of CIO 2960 and CIO 2962 can be allocated as normal inputs.
Select the inputs in the PLC Setup.

PLC Setup
Write the ladder program.
• The input terminals that are used for normal inputs on a
Pulse I/O Module are also used for interrupt inputs,
quick-response inputs, high-speed counter inputs, and
origin searches.
• In the default settings for the PLC Setup, all input terminals are set for use as normal inputs.
• The input terminals that can be used as normal inputs
can be checked in the Pulse I/O Module 0 or 1 assignments on the I/O Module Tab Page.
• Set the Normal Input Operation Setting (Input Time
Constant Setting) in the PLC Setup to set the input time
constant (ON/OFF response time). The settings are the
same for IN00 to IN09 and IN10 to IN19.
The default is 8 ms.
Select from 0 ms (no filter), 0.5 ms, 1 ms, 2 ms, 4 ms, 8
ms, 16 ms, and 32 ms.
• Read the status using the LD instruction or other
instructions.
• Use !LD instructions and other immediate refreshing
version of instructions when immediate refreshing is
required.
Note: Immediate refreshing cannot be performed by the
IORF(097) instruction.

Applicable Input Terminals
The inputs listed in the following table can be used as normal inputs.
The input terminals that are used for normal inputs are also used for interrupt inputs, quick-response
inputs, high-speed counter inputs, and origin searches. The same input terminal can be used for
only one of these functions. For example, if normal output 2 is used, the high-speed counter 1
phase-Z signal + software reset, quick-response input 2, interrupt input 2, and pulse output 1 origin
input (when performing origin searches) cannot be used.

Precautions When Connecting a Two-wire DC Sensor
When using a two-wire sensor, check that the following conditions have been met. Failure to meet
these conditions may result in operating errors.
(1) Relation between voltage when the input is ON and the sensor residual voltage:
VON ≤ VCC − VR
(2) Relation between current when the input is ON and the sensor control output (load
current):
IOUT (min.) ≤ ION ≤ IOUT (max.)
ION = (VCC − VR − 1.5 [Internal residual voltage of input])/RIN
When ION is smaller than IOUT (min), connect a bleeder resistor R. The bleeder resistor constant can be calculated as follows:
R ≤ (VCC − VR)/(IOUT (min.) − ION)
Power W ≥ (VCC − VR)2/R × 4 (allowable margin)
(3) Relation between current when the input is OFF and the sensor leakage current:
IOFF ≥ Ileak
Connect a bleeder resistor if Ileak is greater than IOFF.
Use the following equation to calculate the bleeder resistance constant.
R ≤ RIN × VOFF/(Ileak × RIN − VOFF)
Power W ≥ (VCC − VR)2/R × 4 (allowable margin)

(4) Precautions on Sensor Inrush Current
An incorrect input may occur due to sensor inrush current if a sensor is turned ON after the
PLC has started up to the point where inputs are possible.
Determine the time required for sensor operation to stabilize after the sensor is turned ON
and take appropriate measures, such as inserting into the program a timer delay after turning ON the sensor.

Programming Example
In this example, the sensor's power supply voltage is used as the input to CIO 0.00. A 100-ms timer
delay (the time required for an OMRON Proximity Sensor to stabilize) is created in the program.
After the Completion Flag for the timer turns ON, the sensor input on input bit CIO 0.01 will cause
output bit CIO 1.00 to turn ON.

Creating Ladder Programs
Pulse inputs shorter than the cycle time can be read in the CPU Unit I/O memory using normal instructions by selecting Quick-response Input for the input terminal in the PLC Setup.
The status of CIO 2960.00 to CIO 2960.03 and CIO 2962.00 to CIO 2962.03 can be read using instructions such as the LD instruction.
Example: Setting IN02 to Quick-response Input in the PLC Setup
2960.02
• The minimum pulse width (ON time) that can be read for a quick-response input is 30 µs.
• The status of the input that is stored in the I/O memory for a short input will be cleared during the next
I/O refresh period.
5-4 Creating Ladder Programs
Even if the signal that is input to input terminal 02 is shorter than
the cycle time, the signal will be latched in one cycle and the
status will be stored in CIO 2960.02.

Types of Interrupts

Overview
CJ2M CPU Units normally repeat processes in the following order: overseeing processes, program execution, I/O refreshing, peripheral servicing. During the program execution stage, cyclic tasks (ladder
programs) are executed.
The interrupt function, on the other hand, allows a specified condition to interrupt a cycle and execute a
specified program. Interrupts can thus be used to perform high-speed processing that is not restricted
by the cycle time. The CJ2M CPU Unit performs the following:
(1) When an interrupt occurs, execution of the ladder programs in cyclic tasks is interrupted.
(2) The ladder program in the interrupt task is executed.
(3) When the interrupt task is finished, the ladder program that was being executed is returned to.

Interrupt Factors and Types of Interrupts
Interrupts are classified by the interrupt factor. There are the following three types of interrupts.
• Changes in status of inputs on Pulse I/O Module
→ 6-2 Interrupt Inputs
• PVs of high-speed counters
→ 7-3 High-speed Counter Interrupts
• Specified time interval for timer in the CPU Unit
→ Scheduled interrupts
(Refer to the CJ2 CPU Unit Software Manual
(Cat. No. W473).)
Additional Information
For information on using interrupt tasks, refer to the CJ2 CPU Unit Software User's Manual (Cat.
No. W473).

Interrupt Inputs
Overview
Interrupt inputs can be used in either Direct Mode or Counter Mode.
Interrupt Input in Direct Mode:
A corresponding interrupt task can be executed when an Pulse I/O Module input turns ON or turns OFF.
The PLC Setup or MSKS(690) instruction determines whether the interrupt is triggered when the input
turns ON or when it turns OFF.
Interrupt Input in Counter Mode:
A corresponding interrupt task can be executed when the number of times the Pulse I/O Module input
turns ON or turns OFF reaches the set value (A532 to A535 and A544 to A547) in Increment Mode, or
when it reaches zero in Decrement Mode.
The number of the interrupt tasks started by interrupt inputs must be between 140 and 147.

Precautions for Correct Use
• In Counter Mode, the PV of the interrupt counter in the Auxiliary Area is updated every cycle
as well as when the interrupt task is started. For this reason, the PV of the interrupt counter in
the Auxiliary Area changes irregularly.
Use the PRV(881) instruction to read the latest PV of the interrupt counter.
• Execute the following instructions to change the SV of the counter in Counter Mode.
• If the direction is the same direction (increment/decrement), change the SV of the interrupt
counter in the Auxiliary Area (A532 to A535 and A544 to A547), and then execute the
MSKS(690) (SET INTERRUPT MASK) instruction in the same direction (increment/decrement) to enable interrupt inputs.
• To change the direction from increment to decrement or decrement to increment, disable
interrupt inputs with the MSKS(690) instruction. Change the SV of the interrupt counter in
the Auxiliary Area, and then execute the MSKS(690) instruction to enable interrupt inputs.
Additional Information
In Counter Mode, interrupt tasks will not be started between the execution of a DI(693) instruction and the corresponding EI(694) instruction. Counting will be continued.

Applicable Input Terminals
The inputs listed in the following table can be used as interrupt inputs.
The input terminals that are used for interrupt inputs are also used for normal inputs, quick-response
inputs, high-speed counter inputs, and origin search inputs. The same input terminal can be used for
only one of these functions.
For example, if interrupt input 2 is used, normal input 2, the phase Z/reset method for high-speed
counter 1, quick-response input 2, and the origin input signal for pulse output 1 (when performing origin
searches) cannot be used.

Executing MSKS(690) in a Cyclic Task
Execute the MSKS(690) instruction from the ladder program in a cyclic task to use interrupt inputs.
MSKS(690) has the following two functions and two of this instruction are normally used in combination.
(1) Specifying whether to detect ON or OFF signals.
(2) Enabling interrupts.
• Enabling interrupt inputs in Direct Mode
• Enabling the interrupt input counter in Increment or Decrement Counting Mode
Execution condition
(1) Specifying whether to detect ON or

(2) Enables the interrupt input.
The MSKS(690) instruction must be executed only once to make the settings, so in general execute

Overview
Overview
High-speed counters are used to measure high-speed pulse input signals that cannot be measured by
counter (CNT) instructions.
z Applications
• Detecting the position or length of a workpiece with an input from an incremental rotary encoder.
• Measuring the speed of a workpiece from its position data using frequency measurement and
rotational speed conversion.
• High-speed processing according to the workpiece’s position data.
The present value of the high-speed counter is stored in the Auxiliary Area and can be used as position data. When it reaches preset values, interrupts can be generated. The count can be started and
stopped. Depending on the instruction, the frequency (speed) can be read from the present value of
the high-speed counter.
Changes the PV.

Counter reset method
• Phase-Z + Software reset
The counter is reset when the phase-Z input goes ON while the Reset Bit (A531.00 to
A531.03) is ON.
• Software reset
The counter is reset when the Reset Bit (A531.00 to A531.03) is turned ON.
Operation can be set to stop or continue the comparison operation when the highspeed counter is reset.

Determining High-speed Counters
z Applicable Input Terminals
Terminals that can be used as high-speed counter inputs are shown in the following table.
The terminals that are used for high-speed counter inputs are also used for normal inputs, quickresponse inputs, interrupt inputs, and origin searches. The same input terminal can be used for only
one of these functions.
For example, if high-speed counter 1 is used, interrupt input 2, normal input 2, normal input 6, normal input 7, quick-response input 2, and origin input signal for pulse output 1 (when performing origin searches) cannot be used.
Other functions that cannot be used at the same

Counting Mode Settings
The following counting modes can be selected for high-speed counters: Linear Mode, which counts in a
fixed range, and Ring Mode, which counts in a set range to a specified maximum value.
Linear Mode
Input pulses can be counted in the range between the lower limit and upper limit values. If the pulse
count goes beyond the lower/upper limit, an underflow/overflow will occur and counting will stop.

Input pulses are counted in a loop within the set range.
• If the count is incremented from the maximum ring count, the count will be reset to 0 automatically
and incrementing will continue.
• If the count is decremented from 0, the count will be set to the maximum ring count automatically and
decrementing will continue.
Consequently, underflows and overflows cannot occur when Ring Mode is used.

• There are no negative values in Ring Mode.
• If the maximum ring count is set to 0, the counter will operate with a ring counter maximum
value of FFFF FFFF hex.
• The ring counter maximum value cannot be changed while the comparison operation is in
progress.
• If a value that exceeds the ring counter maximum value is registered in the comparison table,
the comparison operation will not started.
• When the ring counter maximum value is changed, the PV of the high-speed counter will be
cleared to 0.

Reset Methods
Setting a high-speed counter's PV to 0 is called resetting.
There are two reset methods.
• Phase-Z Signal + Software Reset
• Software Reset
Phase-Z Signal + Software Reset
The high-speed counter's PV is reset when the phase-Z signal (reset input) turns ON while the corresponding High-speed Counter Reset Bit (A531.00 to A531.03) is ON.
The CPU Unit recognizes the ON status of the High-speed Counter Reset Bit only at the beginning of
the PLC cycle during the overseeing processes. Consequently, when the Reset Bit is turned ON in the
ladder program, the phase-Z signal does not become effective until the next PLC cycle.

Frequency Measurement
Overview
This function measures the frequency of the high-speed counter (input pulses.)
The input pulse frequency can be read by executing the PRV(881) instruction. The measured frequency
is output in 8-digit hexadecimal and expressed in Hz. The frequency measurement function can be
used with high-speed counter 0 only.
The frequency can be measured while a high-speed counter 0 comparison operation is in progress.
Frequency measurement can be performed at the same time as functions such as the high-speed
counter and pulse output without affecting the performance of those functions.

Temporarily Stopping Input Signal Counting (Gate Function)
If a Gate Bit (A531.08 to A531.11) of a high-speed counter 0 to 3 is turned ON, the high-speed
counter will not count even if pulse inputs are received and the counter PV will be maintained at its
current value. When the Gate Bit of the high-speed counter is turned OFF again, the high-speed
counter will resume counting and the counter PV will be refreshed.
Precautions for Correct Use
The Gate Bit will be disabled if the high-speed counter reset method is set to a phase-Z signal +
software reset and the Reset Bit is ON (i.e., waiting for the phase-Z input to reset the counter
PV.)
Additional Information
Even if a Gate Bit is ON, the INI(880) instruction can be used to change the PV or execute a software reset.

Present Value Comparison
There are two ways to compare the high-speed counter PV: Target Value Comparison and Range Comparison.
Target comparison and range comparison cannot be used for the same high-speed counter at the same
time.
Target Value Comparison
The specified interrupt task is executed when the high-speed counter PV matches a target value registered in the table.
• The comparison conditions (target values and counting directions) are registered in the comparison
table along with the corresponding interrupt task number. The specified interrupt task will be executed when the high-speed counter PV matches the registered target value.
The following examples show the operation of an interrupt task for a comparison table.

• Between 1 and 48 target values can be registered in the comparison table.
• A different interrupt task can be registered for each target value.
• If the PV is changed, the changed PV will be compared with the target values in the table, even if the
PV is changed while the target value comparison operation is in progress.

Precautions for Correct Use
• When the count direction (incrementing/decrementing) changes at a PV that matches a target
value, the next target value will not be matched in that direction.
Set the target values so that they do not occur at the peak or trough of count value changes.

• The comparison conditions (target value and count directions) cannot be set more than once
in the same table. An instruction error will occur if the same comparison conditions appear
twice.
• An instruction error will occur if “when decrementing” is set as the comparison condition when
the high-speed counter is set to Increment Pulse Input Mode.

Range Comparison
The specified interrupt task is executed when the high-speed counter PV enters or leaves the range
defined by the upper and lower limit values.
• The comparison conditions (upper and lower limits and entering or leaving the range) are registered
in the comparison table along with the corresponding interrupt task numbers. The specified interrupt
task will be executed once when the high-speed counter PV enters or leaves the range.

• There are two ways to register comparison tables for range comparison. You can register a fixedlength comparison table with eight ranges, or you can register a variable-length comparison table
with 1 to 32 ranges.
If you register a fixed-length table, the programming and data for CJ1M PLCs can be used without
modifications.
If you register a variable-length comparison table, you can register up to 32 ranges or you can register only the required number of ranges so that less memory is used.
• The ranges can overlap.

• A different interrupt task can be registered for each range.
• The counter PV is compared with the 8 ranges or 1 to 32 ranges once each cycle.
• When the PV of the high-speed counter is changed, the applicable interrupt tasks will be executed if
the new PV falls within any table ranges regardless of whether interrupt execution is specified when
the PV enters or leaves the range.
Precautions for Correct Use
• When more than one comparison condition is met in a cycle, the first interrupt task in the table
will be executed in that cycle. Even if more than one comparison condition is met when the PV
enters or exits the range, the first interrupt task in the table will be executed. The next interrupt
task in the table will be executed in the next cycle.
• Once an interrupt task has been executed from a table, the interrupt task will not be executed
again for the same table until the PV enters or leaves that comparison range. However, regardless of whether interrupt execution is specified when the PV enters or leaves a particular
range, the Range Comparison Condition In-range Flag will be ON when the PV is within the
set range
• Even if a table range is left because the PV is reset to zero (for either a software reset or phase
Z + software reset), the applicable interrupt task will not be executed.
CJ2M CPU Unit Pulse I/O Module User’s Manual
7-27
7-3-2 Present Value Comparison
• The leftmost bit (bit 15) of the word containing the interrupt task number specifies if the interrupt task
is to be executed when the range is entered or left.
Bit 15 = OFF: The interrupt task will be executed when the range is entered.
Bit 15 = ON: The interrupt task will be executed when the range is left.
7 High-speed Counters
Additional Information
The range comparison table can be used without starting an interrupt task when the comparison
condition is met. The range comparison function can be useful when you just want to know
whether or not the high-speed counter PV is within a particular range.
Use the Range Comparison Condition In-range Flags (bits 00 to 07 in A274, A275, A320, and
A312 or words A10128 to A10135) to determine whether the high-speed counter PV is within a
registered range.

Application Examples
Using a Rotary Encoder to Measure Positions
z Functions Used: High-speed Counting
A high-speed counter input can be used by connecting a rotary encoder to an input terminal. A
Pulse I/O Module is equipped with more than one high-speed counter input, making it possible to
control devices for multiple axes with a single PLC.
High-speed counters can be used for high-speed processing, using either target value comparison
or range comparison to create interrupts. Interrupt tasks are executed when the counter value
reaches a specific target value or range.
z Operation
A sheet feeder is controlled to feed constant lengths in a given direction, e.g., for vacuum packing of
food products.

7 High-speed Counters
Length Measurement (Using Interrupts to Read Input Pulses)
z Specifications and Operation
The number of encoder pulse inputs is counted with high-speed counter input 1. Sensor inputs 1
and 2 are read as interrupt inputs at terminals IN00 (CIO 2960.00) and IN01 (CIO 2960.01). The
workpiece length is measured by the number of pulses counted between an ON input at sensor
input 1 and an ON input at sensor input 2.
The program finds the difference between the high-speed counter PVs that are latched for interrupt
inputs IN00 and IN01 and outputs the difference to D10.

Precautions for Correct Use
When the output is being used as a pulse output, connect a load that requires an output current
between 7 and 30 mA.
The Unit's internal components may be damaged if the current exceeds 30 mA.
If the current is below 7 mA, the output waveform's rising edge and falling edge will be delayed
and the output frequency ratings may not be met. If the load requires less than 7 mA, install a
bypass resistor so that the circuit draws a current greater than 7 mA (10 mA is recommended.)
Use the following equations to determine the bypass resistor requirements.

This section provides examples of connections to pulse output 0 or 2. Refer to 3-2-1 Connector Pin
Allocations when using pulse output 1 or 3.
When using an OMRON Servo Drive, a Servo Relay Unit can be used to connect more easily. For
the configuration when using a Servo Relay Unit, refer to Using Servo Relay Units (Sinking Outputs
Only) on page 3-11.
When connecting to a stepping motor or a servo drive from another company, refer to Using Connector-Terminal Block Conversion Units on page 3-9 or Directly Connecting a Self-made Cable with
a Connector on page 3-15.
Precautions for Correct Use
• Any NC input terminals for unused inputs should be connected to the power supply and turned
ON.
• Use shielded cable for connections to stepping motor drives and servo drives. Attach the
shield to the FG terminals at both the Position Control Unit end and drive end of the cable.
• The length of the cable connecting the motor drive must not exceed 3 m.

z Positioning with S-curve Acceleration/Deceleration
With the S-curve acceleration/deceleration positioning, shock and vibration can be controlled by
reducing the initial acceleration rate in comparison with a trapezoidal acceleration/deceleration rate.
This can be selected when there is some leeway in the maximum allowable speed.
Additional Information
• The same type of S-curve acceleration/deceleration can be used for ACC(888) as well.
• The curve for S-curve acceleration/deceleration is formed by applying a tertiary function to the
straight line of the set acceleration/deceleration rates (a tertiary polynomial approximation).
The curve parameters cannot be changed. The maximum acceleration will be 1.5 times that of
trapezoidal acceleration/deceleration for the same acceleration/deceleration rate.
Precautions for Correct Use
• If the starting frequency is set to less than 100 pps, it will automatically be increased to
100 pps.

Implementing Interrupt Feeding
Interrupt feeding is useful for applications such as feeding wrapping material from a position where a
marker was detected for a specified number of pulses (distance), and then stopping it.
8-4-1
Using the IFEED(892) (INTERRUPT FEEDING) Instruction
Interrupt feeding is performed with the IFEED(892) (INTERRUPT FEEDING) instruction. IFEED(892)
controls interrupt feeding by combining the specified pulse output and interrupt input. An interrupt input
is used as a trigger during speed control to switch to position control and then move a specified amount
before decelerating to a stop. An interrupt task is not necessary, so no delays are caused by the interrupt startup time or the occurrence of other interrupts. The accuracy of feeding after an interrupt input
occurs can therefore be improved.

instruction is executed when the interrupt is not masked.
• Interrupt inputs 0, 1, 4, and 5 are used with the IFEED(892) instruction. The terminals used for
interrupt inputs 0 and 1 are also used for the origin and origin proximity inputs for pulse output
0. The terminals used for interrupt inputs 4 and 5 are also used for the origin and origin proximity inputs for pulse output 2. If the IFEED(892) instruction is used for pulse output 0 or 2, do
not use the origin search function.

Defining the Origin
The CJ2 CPU Units have two methods that can be used to define the origin position.
• Origin searches
The ORG(889) instruction outputs pulses to turn the motor according to the pattern specified in the
origin search parameters. As the motor turns, the origin search function defines the origin from the
following three position input signals.
• Origin input signal
• Origin proximity input signal
• CW limit input signal and CCW limit input signal
• Changing the present value of the pulse output
When setting the current position as the origin, execute INI(880) to reset the pulse output PV to 0.
8-5-1
Origin Searches
When the ORG(889) instruction executes an origin search, it outputs pulses to actually move the motor
and defines the origin position using the input signals that indicate the origin proximity and origin positions. The input signals that indicate the origin position can be received from the servomotor's built-in
phase-Z signal or external sensors, such as photoelectric sensors, proximity sensors, or limit switches.

The motor can be moved even if the origin position has not been defined, but positioning operations will be limited as follows:
• Origin return: Cannot be used.
• Positioning with absolute pulse specification: Cannot be used.
• Positioning with relative pulse specification: Outputs the specified number of pulses after setting the present position to 0.

8-5 Defining the Origin
In the following example, the motor is started at a specified speed, accelerated to the origin search high
speed, and run at that speed until the origin proximity position is detected. After the origin proximity
input is detected, the motor is decelerated to the origin search low speed and run at that speed until the
origin position is detected. The motor is stopped at the origin position.

Two sensors, an origin proximity sensor and an origin

an origin search.
An origin proximity sensor and the phase-Z signal from
a Servo Drive are used to execute an origin search.
• Movement is decelerated
when the origin proximity
input is received and the
search is completed on the
origin input.
• If the origin signal is
received while decelerating
for the proximity input, and
origin signal error will occur
and movement will decelerate to a stop. (error code
2002)
• After decelerating for the
origin proximity input,
movement stops on the
phase-Z input from the
Servo Drive. Here, the
error counter reset output
is output to the Servo
Drive to complete the
search.
• Phase-Z inputs are
ignored during deceleration for the proximity
input.
• After decelerating for
the origin proximity
input, movement stops
on the phase-Z input
from the Servo Drive.
Here, the error counter
reset output is output to
the Servo Drive and the
search is completed
when the positioning

received from the Servo
Drive.
• Phase-Z inputs are

An origin return operation moves the motor to the origin position from any other position.
The origin return operation is controlled by the ORG(889) instruction.
The origin return operation returns the motor to the origin by starting at the specified speed, accelerating to the target speed, moving at the target speed, and then decelerating to a stop at the origin position.

The workpiece is set at the starting position using the jogging switch input (IN00: CIO 2960.00).
The workpiece is fed the specified distance (relative) using the positioning switch input (IN01:
CIO 2960.01).
When feeding has been completed, the cutter is activated using the cutter start output (OUT03:
CIO 2961.03).
Feeding is started again when the cutter finished input (IN03: CIO 2960.03) turns ON.
The feeding/cutting operation is repeated for the number of times specified for the counter (C0,
100 times).
When the operation has been completed, the Cut Operation Finished Output (OUT02:
CIO 2961.02). is turned ON.

8-10 Precautions when Using Pulse
Outputs
Movement Direction when Specifying Absolute Pulses
When operating with absolute pulses, the movement direction (CW/CCW) is selected automatically
based on the relationship between the pulse output PV when the instruction is executed and the specified target position. The direction (CW/CCW) specified in an ACC(888), SPED(885), or PLS2(887)
instruction is ignored.
Using CW/CCW Limit Inputs for Pulse Output Functions other than
Origin Searches
Pulse outputs will stop according to the PLC Setup when either the CW or CCW limit input signals turns
ON. It is also possible to select whether the defined origin will be cleared when a CW or CCW limit input
signal turns ON for a pulse output function.
Differences between Set Frequencies and Actual Frequencies
The pulse output frequency of the Pulse I/O Module is determined by dividing the source clock frequency (33,330 MHz) by an integer ratio. Consequently, there may be a slight difference between the
set frequency and the actual frequency.
And that difference increases as the frequency increases. The actual frequency can be calculated from
the following equations.
z Pulse Output System

The INT function extracts an integer from the fraction. The non-integer remainder is rounded.

Combinations of Pulse Control Instructions
A second independent-mode positioning instruction can be started if an independent-mode positioning
instruction is being executed, and a second continuous-mode speed control instruction can be started if
a continuous-mode speed control instruction is being executed.
Operation cannot be switched between the independent and continuous modes. But a PLS2(887)
instruction can be executed while a ACC(888) instruction (continuous mode) is being executed.
It is possible to start another operation during acceleration/deceleration and start another positioning
instruction during positioning.

Origin Search Error Processing
The pulse output function of the Pulse I/O Module performs a basic error check before starting to output
pulses (when the instruction is executed) and will not output pulses if the settings are incorrect.
There are other errors that can occur with the origin search function during pulse output, which may
stop the pulse output.
If an error occurs that stops pulse output, the pulse output's Output Stopped Error Flag will be turned
ON and the Pulse Output Stop Error code will be written to the Error Code word. Use these flags and
error codes to identify the cause of the error.
The Pulse Output Stop Errors will not affect the CPU Unit's operating status. (The Pulse Output Stop
Errors do not cause a fatal or non-fatal error in the CPU Unit.)

PWM Outputs (Variable Duty Ratio
Pulse Outputs)
Overview
A PWM (Pulse Width Modulation) pulse can be output with a specified duty ratio. The duty ratio is the
ratio of the pulse's 'ON time and OFF time in one pulse cycle.
Use the PWM(891) instruction to generate PWM pulses from a pulse output.
The duty ratio can be changed during pulse output.
z Application Example
• Controlling temperature on a time-proportional basis using the PWM output.
• Controlling the brightness of lighting.

Precautions for Correct Use
The actual performance depends on a variety of factors that affect CPU Unit operation such as
the function's operating conditions, user program complexity, and cycle time. Use the performance specifications as guidelines, not absolute values.

Interrupt Input Response Time
The interrupt response time is the time it takes between an OFF-to-ON signal (or ON-to-OFF signal for
down-differentiation) at the interrupt input terminal until the corresponding I/O interrupt task is actually
executed. The total response time is the sum of the hardware response time and software response
time.
