PRECAUTIONS FOR
USE OF AnS SERIES
MODULE
Precautions
• Do not use extension cable longer than 13.2 m (43.28 feet).
• When using an extension cable, keep it away from the main circuit (high voltage
and large current).
• When setting the number of extension stages, set the number in ascending order
to avoid duplicated setting.
• If Q5 B / Q6 B and QA1S6 B extension base units are used in the same
system, be sure to connect Q5 B / Q6 B at first and then QA1S6 B.
Make the setting of the stage number of extension base units, starting from
Q5 B / Q6 B in ascending order. Refer to the QCPU User's Manual (Hardware
Design, Maintenance and Inspection) and check if they can be used.
• The QA1S6 B extension base unit can be used only when all of the AnS series
modules are set to be controlled by the same High Performance model QCPU.
• The Q6 RB cannot be connected as an extension base unit.
• Connect an extension cable between the OUT connector of an extension base
unit and the IN connector of another extension base unit.
• When 66 or more modules are mounted, an intelligent function module
assignment error (error code: 2124, SP. UNIT LAY ERR.) occurs. (Including the
CPU module)
• "No. of CPU" indicates the number of CPU modules set in the "No. of CPU" on
the <<Multiple CPU setting>> tab of the C Controller setting utility.
• Refer to the manuals of the corresponding CPU modules for details of the
programmable controller CPU and Motion CPU.
• When a multiple CPU system is configured using the C Controller module, the
redundant power base unit is not applicable.
