(Note-1): Be sure to use the cable for forced stop input (sold separately). The forced stop cannot be released without using it. If the cable for
forced stop input is fabricated on the customer side, make it within 30m(98.43ft.).
(Note-2): Put the SSCNET cable in the duct or fix the cable at the closest part to the Motion CPU module with bundle material in order to
prevent SSCNET cable from putting its own weight on SSCNET connector.
(Note-3): Q173DSCPU/Q173DCPU(-S1) only
(Note-4): This screw is auxiliary use for module installation to the main base unit. Be sure to fix modules to the main base unit using
supplied fixing screws.
(Note-5): Be sure to use the battery. The programs, parameters, motion devices(#), devices of latch data and absolute position data of
SRAM built-in Motion CPU module are not backed up if the battery is not set correctly.
(Note-6): Q173DSCPU/Q172DSCPU/Q173DCPU-S1/Q172DCPU-S1 only

Application
It takes about 10 seconds to initialize (RUN/STOP
display).
Execute the power cycle of the Multiple CPU
system if the operation stops at initializing for
Initializing several minutes. It may be Motion controller's
hardware fault when it is not improved.
Explain the error symptom (LED display) and get
advice from our sales representative for the
modules with failure.
