Check the following after replacing any faulty Unit.
• Do not replace a Unit until the power is turned OFF.
• Check the new Unit to make sure that there are no errors.
• If you return a faulty Unit for repair, describe the problem in as much detail as possible, enclose this
description with the Unit before returning it.
• For poor contact, take a clean cotton cloth, soak the cloth in industrial alcohol, and carefully wipe the
contacts clean. Be sure to remove any lint prior to remounting the Unit.
Precautions for Correct Use
• Make sure that the required data, including the user program, settings and variables trans-
ferred to a CPU Unit that was replaced and to externally connected devices before restarting
operation. Be sure to include the tag data link settings and routing tables, 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.
• If you replace a slave or Unit, refer to operation manual for the slave or Unit for information
on the data required for individual slaves or Units and redo the necessary settings.
