Version Upgrade Information
The following tables outline changes made for the most recent version upgrade for SYSMAC CJ-Series
Position Control Units.
■ Enhanced Functions for Unit Version 2.0
Changing Multiple-start Acceleration for Relative and Absolute Movement during Direct Operation
Previous versionPresent version (Ver. 2.0 or later)
When executing multiple starts during direct
operation, the acceleration/deceleration times
set for the first start were used.
Changing Accelerations/Decelerations and Changing Deceleration Following Interrupt Inputs for Interrupt Feeding during Direct Operation
Previous versionPresent version (Ver. 2.0 or later)
The speed command could be changed as
long as it was done before the interrupt signal
was input. If an acceleration/deceleration time
was changed, the change would not be effective until the next interrupt feed command. The
acceleration/deceleration times set for the first
start were used for speed changes. The deceleration time set for the first start was used after
interrupt signal input.
Allowing Changes to Acceleration/Deceleration Time during Jogging
Previous versionPresent version (Ver. 2.0 or later)
The only speed changes allowed during jogging were those made with the speed command. If acceleration/deceleration times
changed, the changes were not effective until
the next JOG command. The deceleration time
set when the JOG operation was started was
used for accelerations/decelerations for speed
changes as well as for JOG stops or deceleration stops.
When executing multiple starts during direct operation, the acceleration time set for each of the multiple starts is used and the deceleration time set for the first start is used.
The acceleration/deceleration times can be changed and changes
can be made with the speed command as long as the changes are
made before the interrupt signal is input. The acceleration/deceleration times can also be changed during acceleration and deceleration. The deceleration time set for when the interrupt input occurs is
used following interrupt signal input.
In addition to changes made during JOG operation with the speed
command, speed changes can also be made during JOG operation
by changing the acceleration/deceleration times. Accelerations/decelerations can also be changed during acceleration/deceleration. Accelerations/decelerations can also be changed during
acceleration/deceleration to a fixed speed. The deceleration time
set when the stopping the JOG operation is executed is used for
JOG stops or deceleration stops.
Setting Acceleration/Deceleration Time in Axis Parameters as Time Required to Reach Target Speed
Previous versionPresent version
Acceleration/deceleration times could be set
only as the time required for each axis to go
from the initial speed to the maximum speed.
The acceleration/deceleration time can be set in one of the following ways.
• Set as the time required for each axis to go from the initial
speed to the maximum speed (previous setting method).
• Set as the time required for each axis to go from the present
speed to the target speed. (This simplifies calculating acceleration/deceleration times.)
Addition of Easy Backup Function
Previous versionPresent version
There was no easy backup function.The easy backup function of the CPU Unit can be used to automat-
ically back up and restore the following data from/to flash memory
in the PCU along with all data from the CPU Unit using a Memory
Card in the CPU Unit. It can also compare the data. This makes it
easier to back up all PLC data or to prepare backup data in case
Units are replaced.
• Axis parameters
• Sequence data
• Speed data
• Acceleration/deceleration time data
• Dwell time data
• Zone data
NoteData for all Unit axes is stored at the same time.

■ Enhanced Functions in the Upgrade from Unit Version 2.0 to
Unit Version 2.3
Setting the Number of Unused Axes
Previous versionPresent version (Ver. 2.3 or later)
Emergency stop input wiring was also required
for unused axes.
Setting the CW/CCW Pulse Output Direction
Previous versionPresent version (Ver. 2.3 or later)
The pulse output direction could not be
changed.
Addition of Origin Search Pattern Setting
Previous versionPresent version (Ver. 2.3 or later)
Operation was uneven if a return was performed at the origin proximity and operation
immediately stopped at the origin input signal.
Setting the Position Data When the Origin Signal Stops
Previous versionPresent version (Ver. 2.3 or later)
The stopping point was always 0.The value of the stopping point can be set. Applications in which
Setting the number of unused axes in the common parameters
eliminates the need for emergency stop input wiring for unused
axes.
Bits for reversing the output direction have been added to the axis
parameter areas. Specifying reversal reverses the output section
and is effective for applications using the same wiring but reversed
coordinates.
Reverse mode 3 has been added to enable stopping at the origin
signal at the proximity speed when a return is performed at the origin proximity.
the stopping point is not 0 do not require presetting the present
position.
Jog Operation Setting
Previous versionPresent version (Ver. 2.3 or later)

6-1Applicable Directives
•EMC Directives
6-1-1Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the
customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
The PCUs comply with EC Directives. To ensure that the machine or device in
which a PCU is used complies with EC Directives, the PCU must be installed
as follows:
1,2,3...1. The PCU must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. PCUs complying with EC Directives also conform to the Common Emission Standard (EN61000-6-4). With regard to the radiated emission (10-m
regulations), countermeasures will vary depending on the devices connected to the control panel, wiring, the configuration of the system, and
other conditions. The customer must, therefore, perform final checks to
confirm that devices and the overall machine conform to EC Directives.
6-1-3Installation within Control Panel
Unnecessary clearance in cable inlet or outlet ports, operation panel mounting holes, or in the control panel door may cause electromagnetic wave leakage or interference. In this case, the product may fail to meet EC Directives. In
order to prevent such interference, fill clearances in the control panel with conductive packing. (In places where conductive packing comes in contact with
the control panel, ensure electrical conductivity by removing the paint coating
or masking these parts when painting.)

pulse trains to various motor drivers for positioning.
1-1-1Functions
High-speed ResponseThe Position Control Unit (PCU) responds to instructions from the CPU Unit
within 2 ms. (For more details on the conditions required, refer to Appendix A
Performance Characteristics.)
Memory Operation and
Direct Operation
There are two different control methods. The first is memory operation, in
which the data required for positioning is transferred to the PCU and then
specified for position control, and the second is direct operation, in which the
target position and target speed are set each time from the CPU Unit.
Number of Control Axes
and Output Type
The PCU is available with 1, 2, or 4 control axes. With 2-axis and 4-axis models, linear interpolation is possible for all axes. Either open collector output or
line driver output is available for any number of control axes. Choose the most
appropriate model according to the number of controlled axes and the desired
output type.
Motor Driver Selectable by
Axis
A stepping motor driver and a pulse train input type Servo Drive can be connected to the PCU. It is possible to set different operating modes for different
axes allowing the combined use of different types of motor driver.
Interrupt FeedingWhen an interrupt is input during pulse output, positioning is continued for
only a specified amount and then stopped.
Position and Speed
Control Ranges
Positioning can be performed for positions in the range –1,073,741,823 to
1,073,741,823 pulses and speeds in the range 1 to 500,000 pps in 1-pulse
units. This means that positioning is possible over a wide range with speed
precision.

following table:
Type of dataNumber of data items per axis
Positioning sequences, speeds, positions100

Dwell times19
Zones3
These data items are transferred to the PCU for use. Once they have been
transferred to the PCU they can be saved to the PCU’s flash memory, so
there is no need for battery maintenance.
NoteThere is a limit to the service life of the flash memory. A total of up to 100,000
data saving operations can be performed.
CX-PositionThe PCU is compatible with the Windows-based NC Support Software (CX-
Position) that enables setting of the PCUs in a Windows environment. Using
the CJ-series single-port multi-access function, creation and transfer of
parameters and data for PCUs as well as operation monitoring are possible
from the same environment as the software used for CPU Unit ladder programming (CX-Programmer).
Simple Programming
Using Function Blocks
(See note.)
Function blocks can be used to simplify operation of the PCU in programming
complicated diagrams. There are function blocks for origin searches, ABSOLUTE MOVEMENT commands, and RELATIVE MOVEMENT commands.
NoteRefer to the following documents for details on function blocks.

System ConfigurationSection 1-2
1-2System Configuration
The PCU receives control signals (CW limit, CCW limit, origin, origin proximity, emergency stop, and external interrupt input signals) from devices and a
control panel, and outputs pulse trains to stepping motor drivers and Servo
Drives.

1-3-1Position Control
Positioning can be executed with either an absolute value (i.e., to an absolute
position from the origin) or with an incremental value (i.e., to a relative position
from the present position).
There are two methods for positioning: memory operation and direct operation. Interrupt feeding, in which operation proceeds for a specified amount
after an interrupt input, is also possible.
Direct OperationWith direct operation, positions and speeds are set directly from the CPU Unit
(ladder program), and positioning is executed according to operating commands. It is also possible to change the speed and send commands to move

to different positions while positioning is being performed. Linear interpolation,
however, is not possible during direct operation.
operations, which include data such as positions and speeds) are transferred
to the PCU in advance, and then positioning is executed from the CPU Unit by
specifying those positioning sequences by number. Depending on the completion code that is set, positioning sequences can be executed using independent positioning, automatic positioning, or continuous positioning. In the
following illustrations, “#0” “#1” “#2” and “#3” indicate positioning sequence
numbers.

Control System PrinciplesSection 1-7
1-7-2Control System Principles
Open-Loop SystemIn an open-loop system, positioning is controlled according to the number of
input pulses that the motor receives, and no position feedback is provided.
The PCUs all employ pulse-output-type open-loop systems, and the most
commonly used motor for this type of control system is a stepping motor. The
angle of rotation of a stepping motor can be controlled through the number of
pulse signals supplied to the motor driver. The number of rotations of the stepping motor is proportional to the number of pulses supplied by the PCU, and
the rotational speed of the stepping motor is proportional to the frequency of
the pulse train.

3-3-1System Configuration Considerations
• The additional functions supported by Unit version 2.0 can be used only if
the PCU is installed with a CJ1-H or CJ1M CPU Unit (either CPU Unit Ver.
2.0 or Pre-Ver. 2.0 CPU Unit). These functions cannot be used by PCUs
installed with CJ1 CPU Units.
For details on Unit versions, refer to Unit Versions of CJ-series PositionControl Units on page vi. For details on additional functions supported for
Unit version 2.0, refer to Unit Versions of CJ-series Position Control Units
on page vi.
• The I/O bits allocated to a particular Special I/O Unit are determined by
the unit number that is set by the switch on the front panel of the Unit, and
not by the position in which the Unit is mounted.
• The PCU can be connected to CPU Racks or Expansion Racks (up to 10
PCUs per Rack). Up to 40 PCUs can be connected per CPU Unit.
3-3-2Mounting the Unit
Follow the procedure outlined below to mount the Position Control Unit.
1,2,3...1. Join the PCU to the Rack, ensuring that the connectors engage properly.
2. Secure the PCU by sliding the yellow sliders on the top and bottom until

3. To remove the PCU, slide the sliders in the “release” direction and then
separate the PCU from the Rack.
3-3-3Precautions When Handling the PCU
• Before installing or disconnecting the PCU or connecting cable, be sure to
first turn off both the Programmable Controller and the power supply.
• To minimize any influence from noise, place I/O wiring, high-voltage lines,
and power lines in separate ducts.
• Wire clippings tend to get scattered around during wiring, so leave the
label in place on top of the PCU to prevent any clippings from getting
inside the PCU. Once the wiring has been completed, be sure to remove
the label to provide ventilation.
Remove the label after
completing the wiring.

3-3-5Mounting Precaution for CJ1W-NC413/NC433
Ambient Operating Temperature
The ambient operating temperature of the CJ1W-NC413/NC433 PCUs is 0 to
°C. The ambient operation temperature range, however, can be increased
50
to 0 to 55
lowing conditions.
• A Space Unit is mounted between CJ1W-NC413/NC433 PCUs and any
adjacent Units other than CJ1W-NC413/NC433 PCUs.
• Whenever there are two or more CJ1W-NC413/NC433 PCUs mounted
together on a Rack, a Space Unit is mounted between every two CJ1WNC413/NC433 PCUs.
The following example shows how to use the Space Units when three CJ1WNC413/NC433 PCUs are mounted to the same Rack.
Power Supply Unit
NoteA maximum of 10 Units can be connected in the CPU Rack or any Expansion
Rack, including Space Units. The CPU Unit and CX-Programmer, however,
will not detect the Space Unit as a Unit on the Rack. An error will thus not
occur for any Rack that exceeds the maximum of 10 Units because of the
presence of Space Units. If there are more than 10 Units on a Rack, operating
errors may occur with other Units, such as Special I/O Unit errors. Always be
careful not to have more than 10 Units in any Rack when using Space Units.

3-5Wiring
This section provides motor driver connection examples. When actually connecting a motor driver, be sure to first check the specifications of the motor
driver to be used.
The maximum length of the wiring between the PCU and the motor driver is
2 m for open collector output models and 5 m for line driver output models.

3-5-2Connecting Input Signals
!Caution If the switching capacity is too low it may cause damage to the switch. Con-
nect a switch with a switching capacity of at least 5 mA for each input.
With N.C. inputs, be sure to connect a power supply for unused terminals and
turn them on.
This section shows examples of connecting interrupt, emergency stop, and
CW/CCW limit input signals.
The input section has both N.O. and N.C. inputs. Either can be used depending on the axis parameter settings. For details regarding axis parameters,
refer to 4-4 Axis Parameter Area.
Depending on the setting of the origin search operation pattern, the point at
which the origin proximity signal or the CW/CCW limit signal changes from
ON to OFF is used as the timing for origin signal detection. In this case, use a
sensor with no chattering, such as a photoelectric sensor, for the input. Using
a switch with contacts may cause the position of the origin to be displaced due
to chattering. For details on setting operation patterns for origin searches,
refer to page 153.

3-5-4Wiring Precautions
Operational errors such as dislocation can occur in most electronic control
devices if they are subjected to electronic noise from nearby power lines or
loads. Recovery from such errors is usually very difficult and time consuming.
To avoid such noise-generated operational errors and improve system reliability, always observe the following precautions in wiring the system.
Be sure to use the sizes and materials indicated in the specifications when
connecting power lines and cables.
Power lines (e.g., AC power supply, motor power line) and control lines (e.g.,
pulse output lines, external I/O signal lines) must be wired separately. Never
put these lines into the same duct or make them into a single bundle.
• Attach a multi-layer ceramic capacitor of a thickness of less than 1
the pulse output power supply to improve noise resistance.
• Do not use a 24-V DC or 5-V DC power supply for pulse output in common with the power supply for other I/O.
• Use shielded cable for control lines.
• Connect the shielded cable to the frame ground at both the PCU and the
driver.

• Insert a noise filter into the power supply inlet if noise enters the power
line (e.g., when it is connected to the same power supply as an electric
welder or an electric spark machine or when there is any supply generating high frequency noise).
• Connect to a ground of 100
greater than 1.25 mm

Ω or less and use the thickest possible wire,
.
• Twisted-pair cable is recommended for power lines.
3-6Connection Examples for Different Types of Motor Driver
This section provides examples of wiring the X and Y axes. If the Y and U
axes are also to be used, check the connector pin numbers in 3-4 External I/OCircuitry and wire them in the same way.
Note1. Be sure to connect a power supply for unused N.C. input terminals and turn
them on.
2. Use shielded wire for connecting to stepping motor drivers and Servo
Drives. Connect the shielded cable to an FG at both the PCU and the driver.

Connection of Unused AxesSection 3-7
3-7Connection of Unused Axes
This section provides connection examples for the CJ1W-NC213 and CJ1WNC233 in applications where not all axes are used.
3-7-1Using Only the X Axis and Not the Y Axis on the CJ1W-NC213/
NC233 (with Unit Version 2.3 or Later)
On PCUs with unit version 2.3 or later, wiring is not required for the CW/CCW
limit input signal and the emergency stop input signal for specified unused
axes.
The following figure, based on Example 2: Mode 1 Connection in 3-6 Connec-tion Examples for Different Types of Motor Driver, shows an example of connecting external I/O when only the X axis and not the Y axis is used on the
CJ1W-NC213/NC233. The limit input signal for the X axis is assumed to be
set as an N.C. connection.

To set only the X axis as the axis to be used, set the number of unused axes
to 01 in Axis Parameter Designation of 4-4 Common Parameter Area.
The following table shows the relation for each Unit between the number of
unused axes and the settings.
Setting1-axis Unit2-axis Unit4-axis Unit
0All axes used.All axes used.All axes used.
1Error 0013 occurs. Axis Y not used.Axis U not used.
2Error 0013 occurs.Error 0013 occurs.Axes Z and U not used.
3Error 0013 occurs.Error 0013 occurs.Axes Y, Z, and U not used.
Making this setting eliminates the need to perform wiring for the Y axis.
If other parameters are used in their default settings, the CW/CCW limit input
signal will be set to a N.C. contact input. Therefore, current will flow for the signal when the power supply for the inputs is connected.

Connection of Unused AxesSection 3-7
3-7-2Using Only the X Axis and Not the Y Axis on the CJ1W-NC213/
NC233 (Unit Versions Earlier Than 2.3)
On PCUs with a unit version earlier than 2.3, specified unused axes require
wiring only for the emergency stop input signal.
Based on Example 2: Mode 1 Connection on page 50, the following example
shows the connections for the CJ1W-NC213/NC233 when only the X axis
(and not the Y axis) is used. In this example, the limit input signals for both
axes are set to N.C. contacts. With the CJ1W-NC413/NC433, if the Z axis is
used and the U axis is not used, the connection will be the same with X and Y
replaced by Z and U respectively.

When there is an unused axis, connect the emergency stop input signal (N.C.
contact) and the CW/CCW limit input signals (N.C./N.O. switchable) for that
axis so that they are ON. If the parameters are at their default settings, the
CW/CCW limit input signals are N.C. contact inputs and so connect an input
power supply and keep power ON.
If the emergency stop input signal and the CW/CCW limit input signals for an
unused axis are not ON, a sensor input error (error codes 6000, 6100, or
6101) will be generated for the axis, and the ERC indicator as well as the LED
indicator for the axis will light or flash. The used axis, however, will continue to
operate normally even if an error is generated for the unused axis.
62
NoteIf the CW/CCW limit input signals for the unused axis are set to N.O contacts
using the parameter settings, it is not necessary to wire the CW/CCW limit
inputs. For details, refer to 4-4 Axis Parameter Area.

The common parameters must be set
when using the PCU.
This area contains the parameters for
settings related to axis operation, such
as pulse output type, logic for input signals, operation modes, and maximum
speed values.
Outputs for controlling PCU operation,
such as for direct operation, memory
operation, jogging, and origin search, are
allocated to this area. Information (see
note) relating to the status of the PCU,
such as busy flags, error flags, and external input are input to this area.
This area is for settings such as positions, speeds, and acceleration/deceleration times for direct operation, origin
searches and jogging, as well as positioning sequence numbers for memory
operation. It also contains PCU status
data (see note), such as present positions and the number of the currently
executed positioning sequence.
This area is for settings related to memory operation, such as operation
sequences, positions, speeds, and acceleration/deceleration times. The memory
operation area contains the following six
types of data:
• Positioning sequences
• Speeds
• Positions
• Acceleration times
• Deceleration times
• Dwell times
This data determines zones for the
present positions of axes controlled by
the PCU.

m+1 will be allocated. Specify the bank number in the bank designation setting (word m, bits 08 to 15).
Bank Designation (Word m, Bits 08 to 15)
If user-specified EM Area words (0E) are designated as the location for the
operating data area using the area designation setting (word m, bits 00 to 07),
use this setting to designate a bank number. The following bank numbers can
be designated: 0 (00) to 9 (09), A (0A), B (0B), C (0C). Do not, however, select
a bank that is being used as PLC file memory. If the DM Area words allocated
to Special I/O Units (00) or user-specified DM Area words (0D) are designated as the location of the operating memory area, set the bank designation
to 0 (00). Any other setting will result in an operating data area specification
error (error code 0010).
NoteDo not set a bank number for a bank that is being used as PLC file memory. If
a bank that is being used as PLC file memory is set, the operating data area
settings will not be reflected in PCU operation and this will result in malfunction. When there are several PCUs mounted to the same PLC, be sure to set
the operating data areas for the PCUs so that they do not overlap with each
other. The PCU will not detect an error if operating data areas overlap, and
this may result in malfunction.
For details on the EM Area banks and how to use them as PLC file memory,
refer to the SYSMAC CS/CJ Series Programmable Controllers ProgrammingManual (W394).
Beginning Word of Operating Data Area (Word m+1)
If user-specified DM Area words (0D) or user-specified EM Area words (0E)
are designated as the location for the operating data area using the area designation setting (word m, bits 00 to 07), use this setting to designate the
beginning word of the operating data area. The beginning word is set in hexadecimal. The following settings are possible (varies with the model):
NC1@3: 0000 to 7FE8 Hex (0 to 32744)
NC2@3: 0000 to 7FD8 Hex (0 to 32728)
NC4@3: 0000 to 7FB8 Hex (0 to 32696)
If DM Area words allocated to Special I/O Units (00) are designated as the
location for the operating data area, this setting will not be used.
