longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.
Observe the following precautions when using the MC Unit or the CPU Unit.
Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
• Always ground the system to 100
protect against electrical shock.
• Always turn OFF the power supply to the Unit before attempting any of the
following. Not turning OFF the power supply may result in malfunction or
electric shock.
• Mounting or dismounting the MC Unit or any other Units.
• Assembling the Units.
• Setting rotary switches.
• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
the CPU Unit, the MC Unit. or the system, or could damage the CPU Unit or
MC Unit. Always heed these precautions.
• Check the task configuration before creating MC program for the MC Unit.
Set the task configuration (axis configuration, number of tasks, and task
axis definition) using the unit parameters within the system parameters. If
changes are made to the task configuration, the MC program must be
changed as well.
• After transferring the system parameters, G-language program, or posi-
tion data to the MC Unit, be sure to save the data in flash memory within
the MC Unit (using the data save command from the CX-Motion 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, the unit parameters and machine parameters
will not be changed and the System Set Error, which can occur when the
system parameters are transferred to the MC Unit, will not be cleared.
• Do not turn OFF the power supply to the Unit while data is being written to
flash memory. Doing so may cause problems with the flash memory.
• Confirm that no adverse effects will occur in the system before changing
the operating mode of the Teaching Box.
• When a wiring error occurs, be sure to reset the power supply to the Unit,
check the wiring, and reset the machine parameters within the system
parameters.
