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 the Q5 B and Q6 B extension base units are used in the same system, there
are no restrictions on the connection order of the Q5 B and Q6 B.
However check whether they are applicable or not, referring to the QCPU User's
Manual (Hardware Design, Maintenance and Inspection).
• The QA1S6 B and Q6 RB cannot be used as extension base units.
• 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)
• The C Controller module does not allow bus connection of the GOT.
• "No. of CPU" indicates the number of CPU modules set in the "No. of CPUs" on
the <<Multiple CPU setting>> tab of the C Controller setting utility.
• Refer to the Motion CPU manual for details of the Motion CPU.
• When a multiple CPU system is configured using the C Controller module, the
redundant power base unit is not applicable.
