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.
