The required time has been shortened as follows:
7.5 ms to 37.5 ms
Using Interpolation Commands in Pass Operations
Previous versionsPresent version (unit Ver. 2.0 or later)
To execute a pass operation when the axis was
stopped required two interpolation commands just for
the first movement.
Example:
A pass operation can be executed when the axis is
stopped using a single interpolation command.
Example:
PASSMODE;
WHILE #MW0000==0;
INC MOVEL [J02]100 F1000;
WEND;
etc.
Acceleration/Deceleration Time During Pass Operation
Previous versionsPresent version (unit Ver. 2.0 or later)
Parallel processing had to be executed using the PARALLEL command to change the acceleration/deceleration time during a pass operation, making changes at
user-specified timing difficult.
• The acceleration/deceleration time can be changed
during pass operation.
• The acceleration/deceleration time can be easily
switched using the newly added parameter, as follows:
MOVEL [J01]1000 F1000

The interpolation feed deceleration time was used to
decelerate to a stop during pass operation.
Example:
Pass Mode Select P00M06 = 0
Interpolation feed acceleration time Ta=P0MM02
Interpolation feed deceleration time Td=P00M03
• The interpolation time used for the pass operation
(interpolation feed acceleration time or deceleration
time) is used to decelerate to a stop during pass operation.
Example:
Pass Mode Select P00M06 = 0
Interpolation feed acceleration time Ta=P0MM02
Interpolation feed deceleration time Td=P00M03
• To decelerate to a stop using the interpolation feed

xxii
Operating Environment Precautions5
• Do not pull on the cables or bend the cables beyond their natural limit. Doing so may break the
cables.
• Do not turn off the power supply to the Unit while data is being written to flash memory.
Doing so may cause problems with flash memory.
• Confirm that user program for proper execution before actually running it on the Unit.
Not checking the program may result in an unexpected operation.
• Check the user program for proper execution before actually running it on the Unit.
Not checking the program may result in an unexpected operation.
• Resume operation only after transferring to the new MC Unit the contents of the parameters, position
data, and other data required for resuming operation.
Not doing so may result in an unexpected operation.
• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area,
and other data required for resuming operation. Not doing so may result in an unexpected operation.
• After transferring the system parameters, servo parameters, programs, position data, and CAM data
to the MC Unit, be sure to save the data in flash memory within the MC Unit (using the data save
command from support tool or CPU Unit) before turning OFF the power supply to the Unit. Transferring the data to the MC Unit will simply save the data in the internal memory (S-RAM) of the MC Unit
and this data will be deleted when the power supply to the Unit is turned OFF.
• After transferring the system parameter data to the MC Unit and saving the data to flash memory, be
sure to reset the power supply to the unit or restart the Unit. Otherwise, some of the unit parameters
and machine parameters will not be changed.
• The Machine lock function is enabled in each axis, for the effects on the operations with multiple axes
such as interpolation operation be sure to machine lock all of relative axes in order to prevent the
interference with other axes or devices.
• If axes are stopped during a synchronized operation, however, the synchronization of the master axis
and slave axes positions will be cancelled. For that reason, be aware of the interference with other
axes or devices when restarting up.
• When the load OFF status is occurred in the CPU Unit during manual operation such as JOG, which
is performed by operating input variables from the MC Unit's program, the operation will be continued
for one-cycle of the Unit. Using the WHILE command to repeat until given condition is satisfied, however, it continues to operate even load-OFF has occurred, be aware of the interference with other
axes or devices.
• Parameters and programs for MC Units with unit version 2.0 or later can be transferred to pre-Ver. 2.0
MC Units, but the new and upgraded functions for unit Ver. 2.0 will be disabled.
• Do not attempt to take any Units apart, to repair any Units, or to modify any Units in anyway.
5Operating Environment Precautions

Conformance to EC Directives6
6Conformance to EC Directives
6-1Applicable Directives
EMC Directives
6-2Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards to 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). The customer, however, must check whether
the products conform to the standard in the system used by the customer.
EMC related performance of the OMRON devices that comply with EC Directives would 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 (Electro-Magnetic Compatibility) standards are as follows:
The CS1W-MCH71 “MC Unit” comply with EC Directives. To ensure that the machine or device in
which an MC Unit is used complies with EC Directives, the MC Unit must be installed as directed
below:
1. The MC Unit must be installed within a control panel.
Use a control panel like SA20-712 (Nitto Electronics) or similar to this.
2. Reinforced insulation or double insulation must be used for the DC power supplies used for the
communications and I/O power supplies.
3. MC Units complying with EC Directives also conform to the Common Emission Standard
(EN50081-2). 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 Directions.
6-4Installation 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.)

SECTION 1
Features and System Configuration
The section introduces the features and system configuration of the CS1W-MCH71 CS-series Motion Control Unit. It also
describes product operating principles and provides product specifications.
The CS1W-MCH71 model is a CS-series Motion Control Unit that can control
thirty axes. An internal motion language programming is mounted, so that it
can perform the advanced motion control operations.
1. Position Control
• Point-to-Point Control: With point-to-point (PTP) control, positioning is
controlled independently for each axis. The pathway varies according to the travel distances, the
feed rates, and so on.
• Continuous Path Control:With continuous path (CP) control, not only the
start position and target position are controlled
but also the path between those points. Functions such as linear interpolation, circular interpolation, helical circular interpolation, and
traverse can be performed.
2. Speed Control
It makes the motor run at the specified speed, it also specifies the rate of
speed change.
3. Torque Control
It generates specified Torque and specifies the rate of Torque change.
4. Synchronous Control
• Electronic Shaft: Functions the same as for the rolls connected to the
gearbox with a gearshift.
• Electronic Cam: Functions the same as for the Machine CAM.
The MC Unit has been developed for use in simple positioning applications
using servomotors. Applicable machines are as follows:
ers, etc. (Palletizers and depalletizers are devices
used for loading goods onto pallets or for unloading
them from pallets. Loaders and unloaders are
devices that have shelves corresponding with the
steps of a multi-step press and used for inserting or
removing all the materials at one time.)
automated assembling machines (such as coil
winding, polishing, hole punching), etc.
NoteThe MC Unit is not designed to perform the interpolation movement like a lin-
ear interpolation, a circular interpolation, or a helical circular interpolation with
horizontal articulated robots or cylindrical robots, because it does not support
coordinate conversions (cylindrical coordinate rotation function). The MC Unit
can, however, perform PTP control with these robots.

1-3Basic Operations
1-3-1Applicable Machines
The MC Unit was developed for the purpose of motion control using servomotors.
Even though it depends on the machine accuracy, use an encoder, which is
capable to detect 5-10 times more accurate than the machine accuracy.
Applicable machines
1,2,3...1. Assembling Systems
Simple robots, package machinery (horizontal type forming and vertical
type forming), filling machine, grinder, drilling machinery, simple automated assembling machines, etc.
2. Conveyor Systems
XY tables, palletizers/depalletizers, loaders/unloaders, etc.
NoteThe MC Unit is not designed to perform linear interpolation, circular interpola-
tion, or helical circular interpolation with horizontal articulated robots or cylindrical robots, because it does not support coordinate conversions. The MC
Unit can, however, perform PTP control with these robots.
1-3-2Position Control
The MC Unit offers the following three types of motion control:
•PTP Control
• CP Control (linear interpolation and circular interpolation)
• Interrupt Feeding
Control programs are created in the Motion language.
PTP ControlPTP control is used to control each axis (J01 and J02 axis) independently.
Positioning time depends on the travel distance and speed of each axis.
Example: Moving from the origin to the J01-axis coordinate of 100 and J02-
axis coordinate of 50 at the same speed.
Positioning is executed separately for each axis, so travel between the two
points is carried out as shown in the diagram below:

The servo system used by and the internal operations of the MC Unit are
briefly described below.
1-4-1Control System Configuration
Semi-closed Loop SystemThe MC unit uses the servo system called the semi-closed loop system.
This system is designed to detect actual machine travel distance for a command value using rotations of the motor and the detected value is fed back to
the MC unit. The unit computes and compensates the error between the command value and actual travel distance to make it zero.

Unit
Calculation Method for
Unit Cycle
The MC Unit holds Control Cycle for the entire Unit and Communication Control Cycle.
The system software calculates each control cycle, and it operates when "Unit
cycle: Communications cycle" is "1:1" or "2:1".
Calculation methods for each control cycle are as follows:
• Calculates the Unit Cycle
• Calculates the Communication Cycle
• Adjusts and matches the Unit Cycle and Communications Cycle.
Basic formula for calculating Unit Cycle is shown below:
Unit Cycle [
of parallel branches) + (0.3
µs] = (115.0 × No. of axes)+(165.0 × No. of motion tasks × No.
× No. of general allocated words) + 350.0 --- (1)
• No. of axes:No. of axes allocated in [P1AA01:Physical axis setting] (Sum
of virtual and actual axes)
• No. of Motion tasks: P00001 [No. of Motion tasks]
• No. of parallel branches: P00002 [No. of parallel branches]
• No. of general allocated words:
No. of Allocated words to be used as general purpose I/O (Sum of inputs
and outputs)
Note for P00003 [Unit Scan time]
When P00003 [Unit Scan time] is greater than the result of the formula (1), the
formula (2) below is to be used.
Unit Cycle [
µs] = P00003 × 1000 ---(2)
19
PerformanceSection 1-7
Determining Unit Cycle
The Unit Cycle can be determined by rounding up the Unit Cycle [us] that was
found by the formula (1) or (2) to 1ms/2ms/3ms/4ms/6ms/8ms.
Calculation Method for
Communications Cycle
Adjusting and Matching
Unit Cycle and
Communications Cycle
Basic formula for calculating Communications Cycle is shown below:
Communications Cycle [
µs]= ((No. of allocated nodes + No. of Retries) ×
133.3 + 26.2) × 1.1 ---(3)
• No. of Allocated Node:No. of MECHATROLINK-II slaves (only physical
axes) allocated in [P1AA01: Physical Axis Setting]
• No. of Retries: No. of retries specified in [P00009: MECHATROLINK No.
of retrial nodes setting] (= 0-7).
Note for W-series Servo Driver
When a W-series Servo Driver and NS115 communications module are allocated as slaves, Minimum communications cycle of MECHATROLINK-II will
be 1ms. If the Communications cycle that was found by the formula (3) was
less than 1ms, the formula (4) below is to be used.
Communications cycle [
µs] = 1000 ---(4)
Determining Communications Cycle
The Communications Cycle can be determined by rounding up the Communications Cycle [
µs] that was found by the formula (3) or (4) to 1ms/2ms/3ms/
4ms.
Determine the combination of the Unit Cycle and Communications Cycle
using the following table:
Control cycle relationsAdjusting/matching method
Unit Cycle < Communications Cycle
Unit Cycle = Communications Cycle
Unit Cycle > Communications Cycle
Communications Cycle remains the same, and Unit Cycle
is adjusted so that it is the same as Communications
Cycle.
Used as they are.
When Unit Cycle is 8ms:
The Communications Cycle is 4ms.
Other cases:
When Unit Cycle/Communications Cycle = 2 or less:
The Unit Cycle remains the same, and the Communications Cycle will be the half of the Unit Cycle.
Besides the above case:
The Unit Cycle remains the same, but the Communications Cycle will be the same as the Unit Cycle.

Always turn OFF the CPU Unit before mounting or removing a MC Unit or
connecting or disconnecting cables to or from the MC Unit.
Place the port connecting cables in a different duct from those for high-voltage
lines or power lines to prevent the effects of electrical noise from these lines.
Do not remove the protective label from the top of the unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring. Remove the label after wiring has been
completed to allow air circulation needed for cooling.

3-4-1Wiring Precautions
Heed the following precautions when wiring the MC Unit to the servo drivers
and motors.
Electronically controlled equipment may malfunction because of noise generated by power supply lines or external loads. Such malfunctions are difficult to
reproduce; hence, determining the cause often requires a great deal of time.
The following tips should aid in avoiding noise malfunction and improving system reliability.
Use electrical wires or cables of designated sizes as specified in the instruction manual for the servo driver.
Separate power cables (AC power supply lines and motor power supply lines)
from control cables (pulse output lines and external input signal lines). Do not
group the two types of cable together or place them in the same conduit.
Using the laminated ceramic capacitor of 1
supply will improve noise-resistance.
Use shielded cables for control lines.
For inductive loads such as relays or solenoid valves, connect surge absorb-
ers.
The connecting cable for the servo driver must be the specified cable with ring
core.

Note(1) Connect a surge-absorbing diode or surge absorber close to the relay.
Use a surge absorbing
diode with a voltage tolerance at least five times
greater than the circuit voltage.
(2) Noise may interfere from the power supply line if the same power supply
as the electric welder or spark erosion machine is used for the MC Unit,
or if there is a source of high-frequency noise around. If it occurs, insert
the noise filter at the input section of the power supply.
(3) Use the twisted pair-cable for the power line.
(4) Provide grounding of 100
Ω or less and use the thickest possible wire,
greater than 1.25 square mm.

Data Access MethodThe following methods are used to access to each data. For further details,
refer to SECTION 5 Data Transfer and Storage (page 194).
1,2,3...1. Use the support tool (MC-Miel).
2. Execute IOWR/IORD instructions (Intelligent I/O Write/Read) from the ladder program.
3. Variables can be used in the MC Unit's programs.
"IORD/IOWR Control Address" is the internal address to identify data when
IORD/IOWR instructions are executed from the ladder program. Global variables, input variables, output variables, or task variables cannot be accessed.
See 4-3 Variables (page 91) for details.
Basic Data UsageSystem parameters:Created with the support tool (MC-Miel), and transferred
to the MC Unit. Using the IOWR instruction during CPU
Unit's operation can change the system parameters as
needed.
Position data:Created with the support tool (MC-Miel), and transferred
to the MC Unit. Using the IOWR instruction during CPU
Unit's operation can change the position data as needed.
It is possible to change the position data also by using
MC Unit's program.
System variables:Read with the IORD instruction from the ladder program
while the CPU Unit is running.
It is also possible to read it from MC Unit's programs.
Servo parameters: Created with the support tool (MC-Miel), and transferred
to the MC Unit. Using the IOWR instruction during the
CPU Unit's operation can change the system parameters
as needed. To use the IOWR instruction, the axis whose
parameters are to be changed has to be specified in
advance.
Other variables:Global general variables, input variables, output vari-
ables, and task variables can be used in MC Unit's programs.

Explanation
Specifies the numbers of both parallel branching and simultaneous execution
commands in each motion task.
This setting affects the maximum number of branches for PARALLEL (parallel
execution) command. (It is limited by the value set here.) When the number of
parallel branches in a motion program is smaller than the value set in this
parameter, the value obtained from dividing the value in the parameter by the
actual number of branches becomes the number of commands that can be
executed simultaneously for each row of each branched program.
The number of multiple execution commands in each unit cycle is applied to
the simultaneous execution.

Explanation
• Sets the maximum speed on machine's side for when operating with commands, such as MOVE, MOVEL commands, etc., that include interpolation.
The maximum rapid feed rate can be set using the following calculation
formula:
× Max. No. of motor rotations [rotation/min] × P5AA06 [machine rotation
speed]/P5AA05 [motor rotation speed]
The maximum speed is limited by (32767 command unit/unit scan).
P2AA01 [command unit/min]
Ts[s]: Unit scan time
This indicates the unit cycle time of MC Unit determined by the numbers of
tasks, axes, parallel branches, and refreshed words.
1966020000:
The upper limit of speed resolution is 32767 [command unit/unit scan]. The
value 1966020000 is obtained by converting 32767 [command unit/unit
scan] to the unit of minutes (32767

(−2147483648 to 2147483647)
Explanation
Sets the software limit value in the positive direction.
An error will occur when the command value created in every unit scan
exceeds this software limit.
The value has to satisfy the following conditions:
P3AA02 [command unit] = + direction upper limit/minimum setting unit
P3AA03 [command unit] =
P3AA03 < P3AA02
Ex) When positioning X-axis (ball screw) in 0.01mm unit (P5AA01, P5AA2)
−100 to 100mm, the following values are to be set:
within
P3AA02 = 100mm/0.01mm = 10000 [command unit]
P3AA03 =
−100mm/0.01mm = −10000 [command unit]
NoteThe setting of this parameter is ignored in the following cases:
• When Software limit enabled/disabled (P3AA04) is set to either "0" or "2".
• When an origin has not been defined.
• When Axis feed mode (P5AA07) is set to 0010h (unlimited length).
