1.3.5 Restrictions on motion systems
(1) Combination of Multiple CPU system
(a) Motion CPU module cannot be used as standalone module.
Be sure to install the universal model PLC CPU module (Q03UDCPU/
Q04UDHCPU/Q06UDHCPU) to CPU No.1.
For Universal model PLC CPU module, "Multiple CPU high speed
taransmission function" must be set in the Multiple CPU settings.
(b) Only Multiple CPU high speed main base unit (Q38DB/Q312DB) can be
used.
(c) The combination of Q173DCPU/Q172DCPU and Q173HCPU(-T)/
Q172HCPU(-T)/Q173CPUN(-T)/Q172CPUN(-T) cannot be used.
(d) Up to four modules of PLC CPU modules (Q03UDCPU/Q04UDHCPU/
Q06UDHCPU/Motion CPU modules can be installed from the CPU slot (the
slot on the right side of power supply module) to slot 2 of the main base unit.
CPU modules called as CPU No.1 to CPU No.4 from the left sequentially.
There is no restriction on the installation order of CPU No.2 to No.4.
For CPU module except CPU No.1, an empty slot can be reserved for
addition of CPU module. An empty slot can be set between CPU modules.
However, the mounting condition when combining with the High
performance PLC CPU module/Process CPU module/PC CPU module/C
controller module is different depending on the specification of CPU
modules, refer to the Manuals of each CPU modules.
(e) It takes about 10 seconds to startup (state that can be controlled) of Motion
CPU. Make a Multiple CPU synchronous startup setting suitable for the
system.
(f) Execute the automatic refresh of the Motion CPU modules and PLC CPU
modules (Q03UDCPU/Q04UDHCPU/Q06UDHCPU) by using the automatic
refresh of Multiple CPU high speed transmission area setting.
When the High performance PLC CPU module/Process CPU module/PC
CPU module/C controller module is mounted in the combination of Multiple
CPU system, the Motion CPU module cannot be execute the automatic
refresh with these modules.
(g) Use the Motion dedicated PLC instructions that starts by "D(P).". The Motion
dedicated PLC instructions that starts by "S(P)." cannot be used. When the
High performance PLC CPU module/Process CPU module/PC CPU
module/C controller module is mounted in the combination of Multiple CPU
system, the Motion dedicated PLC instruction from these modules cannot be
executed.
