Precautions for Safe Use

• Use the NX_AryDOutTimeStamp (Write Digital Output Array with Specified Time Stamp) instruction
only after you confirm that InOperation from the MC_DigitalCamSwitch (Enable Digital Cam Switch)
instruction is TRUE.
• If you change the unit conversion settings, perform homing again. If you do not perform homing, un-
intended operation of the controlled system may occur.
Restoring Data
• You cannot back up, restore, or compare some or all of the settings for certain slaves and Units.
Also, you cannot back up, restore, or compare data for disabled slaves or Units. After you restore
data, sufficiently confirm that operation is correct before you start actual operation.
• If any of the following conditions is met, clear the absolute encoder home offsets from the list of data
items to restore, and then restore the data. Then, define the absolute encoder home again. If you do
not define home, unintended operation of the controlled system may occur.
a) The Servomotor or Servo Drive was changed since the data was backed up.
b) The absolute encoder was set up after the data was backed up.
c) The absolute data for the absolute encoder was lost.
Transferring Programs
• When you use the program transfer from SD Memory Card whose Startup Mode setting is set to
RUN mode, the operating mode changes to RUN after the transfer is completed regardless of the
status and setting before the transfer. Use this function after you confirm that system startup does
not cause any problem.
• Always confirm safety at the connected equipment before you perform the following operations
when the device output hold configuration is set to enable. The equipment may operate unexpected-
ly because the last status for outputs is retained.
a) Changing the operating mode of the CPU Unit
b) When downloaded
• When you transfer the values retained in the memory of the CJ-series Units, always check the set
values of the Device Output Hold Configuration and make sure that the destination is safe.
The devices or machines may perform unexpected operation regardless of the operating mode of
the CPU Unit.
Battery Installation and Replacement
• The Battery may leak, rupture, heat, or ignite. Never short-circuit, charge, disassemble, heat, or in-
cinerate the Battery or subject it to strong shock.
• Dispose of any Battery that has been dropped on the floor or otherwise subjected to excessive
shock. Batteries that have been subjected to shock may leak if they are used.
