NJ-series CPU Unit Hardware User’s Manual (W500)
• Make sure that the required data, including the user program, configurations, settings, variables, and
memory used for CJ-series Units, is transferred to a CPU Unit that was replaced and to externally
connected devices before restarting operation.
Be sure to include the tag data link settings, routing tables, and other CPU Bus Unit data, which are
stored in the CPU Unit.
• The absolute encoder home offsets are backed up with a Battery in the CPU Unit as absolute
encoder information. When you change the combination of the CPU Unit and Servomotor, e.g., when
you add or replace a Servomotor, define the absolute encoder home again.
• The performance may be different if the hardware revisions are different. Before you transfer the user
program, data, and parameter settings to the CPU Units with the different hardware revisions, check
them for proper execution and then use them for actual operation.
• Dispose of the product and Batteries according to local ordinances as they apply.
• The following information must be displayed for all products that contain primary lithium batteries with a
perchlorate content of 6 ppb or higher when shipped to or transported through the State of California, USA.
