(2) Modules controlled by a Motion CPU cannot be installed in the extension base
unit QA1S6
B. Install them in the CPU base unit Q3 B or extension base unit
Q6
B.
(3) A total of eight base units including one CPU base unit and seven extension base
units can be used. However, the usable slots (number of modules) are limited to
64 per system including vacant slots. If a module is installed in slot 65 or
subsequent slot, an error (SP. UNIT LAY ERROR) will be occur. Make sure all
modules are installed in slots 1 to 64. (Even when the total number of slots
provided by the CPU base unit and extension base units exceeds 65 (such as
when six 12-slot base units are used), an error does not occur as long as the
modules are installed within slots 1 to 64.)
