2 SYSTEM CONFIGURATION
2.1.4 Restrictions on Motion controller
(1) Only extension base unit (Q52B/Q55B) of type not requiring power supply module
can be used.
(2) Q170MCPU Multiple CPU system is composed of the PLC CPU area (CPU No.1
fixed) and Motion CPU area (CPU No.2 fixed). Other CPU (CPU No.3, CPU No.4)
cannot be set.
(3) It takes about 10 seconds to startup (state that can be controlled) of Motion
controller. Make a Multiple CPU synchronous startup setting suitable for the
system.
(4) Execute the automatic refresh of the Motion CPU area and PLC CPU area by
using the automatic refresh of Multiple CPU high speed transmission area setting.
(5) The Motion modules, I/O modules and intelligent function modules, etc. can be
installed on the extension base unit only.
(6) The CPU modules cannot be installed on the extension base unit.
(7) When using the GOT with bus connection, connect the GOT after the extension
base unit of stage 1 in the case with the extension base unit use, and connect
directly to the Motion controller in the case with the extension base unit unused.
(8) The synchronous encoder interface module Q172DEX/Q172EX(-S1/-S2/-S3)
cannot be used.
(9) Be sure to control the Motion modules (Q172DLX, Q173DPX) with the Motion
CPU area. They will not operate correctly if PLC CPU area is set by mistake.
(10) Q172LX/Q173PX(-S1) for Q173HCPU(-T)/ Q172HCPU(-T)/Q173CPUN(-T)/
Q172CPUN(-T)/Q173CPU/Q172CPU cannot be used.
(11) Motion CPU area cannot be set as the control CPU of intelligent function module
(except some modules) or Graphic Operation Terminal(GOT).
(12) Be sure to set the battery.
(13) There are following methods to execute the forced stop input.
• Use a EMI connector of Q170MCPU.
• Use a device set in the forced stop input setting of system setting
(14) Forced stop input for EMI connector of Q170MCPU cannot be invalidated by the
parameter.
When the device set in the forced stop input setting is used without use of EMI
connector of Q170MCPU, apply 24VDC voltage on EMI connector and invalidate
the forced stop input of EMI connector.
