Intended Audience 1
1 Intended Audience
This manual is intended for the following personnel, who must also have
knowledge of electrical systems (an electrical engineer or the equivalent).
• Personnel in charge of installing FA systems.
• Personnel in charge of designing FA systems.
• Personnel in charge of managing FA systems and facilities.
2 General Precautions
The user must operate the product according to the performance specifica-
tions described in the operation manuals.
Before using the product under conditions which are not described in the
manual or applying the product to nuclear control systems, railroad systems,
aviation systems, vehicles, combustion systems, medical equipment, amuse-
ment machines, safety equipment, and other systems, machines, and equip-
ment that may have a serious influence on lives and property if used
improperly, consult your OMRON representative.
Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide
the systems, machines, and equipment with double safety mechanisms.
This manual provides information for programming and operating the Unit. Be
sure to read this manual before attempting to use the Unit and keep this man-
ual close at hand for reference during operation.
!WARNING It is extremely important that the CX-Motion-MCH and related devices be
used for the specified purpose and under the specified conditions, especially
in applications that can directly or indirectly affect human life. You must con-
sult with your OMRON representative before applying Motion Control Units
and related devices to the above-mentioned applications.
3 Safety Precautions
!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing
so may result in electric shock.
!WARNING Never touch any of the terminals while power is being supplied. Doing so may
result in serious electric shock.
!WARNING Always back up programs, parameter data, position data, or cam data to the
flash memory after it has been transferred to the Motion Control Unit. If trans-
ferred data is not backed up in flash memory, the previous settings may be
used the next time the power is turned ON, resulting in a malfunction.
!Caution Check that the axis number is correct before operating an axis from the CX-
Motion-MCH.
!Caution Confirm safety at the destination node before transferring parameters or other
data to another node. Doing either of these without confirming safety may
result in injury.

xix
Operating Environment Precautions 4
!Caution Do not save data (i.e., do not write data to flash memory) while the motion
program is being executed or the motor is operating. Unexpected operation
may result.
4 Operating Environment Precautions
!Caution Do not operate the MC Unit in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified
in the specifications.
• Locations subject to condensation as the result of severe changes in tem-
perature.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
!Caution Take appropriate and sufficient countermeasures when installing the MC Unit
in the following locations:
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
5 Application Precautions
Observe the following precautions when using the CX-Motion-MCH.
• Confirm that the correct unit number is specified for the destination node
before transferring parameters or other data to the Motion Control Unit.
• Confirm that programs, set parameters, and position data operate prop-
erly before using them in actual applications.
• Do not turn OFF the power to the Unit while writing to flash memory.
Doing so may result in damage to the flash memory.
• After replacing an MC Unit, restart operation only after saving the
required parameters, position data, and other data in the MC Unit.
• After transferring system parameters, servo parameters, programs, posi-
tion data, or cam data to the MC Unit, always save the data to flash mem-
ory in the MC Unit before turning OFF the power supply using either the
Support Software or a command from the CPU Unit. If data is transferred
to the MC Unit without saving it to flash memory, the data will exist only in
S-RAM in the MC Unit and will thus be lost when the power supply to the
MC Unit is turned OFF.
• After transferring system parameters to the MC Unit, always save them in
flash memory and then either cycle the power supply to the MC Unit or
restart the MC Unit as a CPU Bus Unit from the CPU Unit. Some system
parameters will not be updated if the MC Unit is not restarted.
