2 SYSTEM CONFIGURATION
2.1.3 Function explanation of the Q173CPU(N)/Q172CPU(N) Motion CPU modules
(1) Up to 32 axes servo amplifiers per 4 systems (up to 8 axes per 1 system) can be
used in Q173CPU(N). Up to 8 axes servo amplifiers per 1 system can be used in
Q172CPU(N).
(2) It is possible to set the program which synchronized with the motion operation
cycle and executed at fixed cycle (0.88[ms], 1.77[ms], 3.55[ms], 7.11[ms],
14.2[ms]).
(3) It is possible to execute a download of servo parameters to servo amplifier, servo
ON/OFF to servo amplifier and position commands, etc. by connecting between
the Q173CPU(N)/Q172CPU(N) and servo amplifier with SSCNET cable.
(4) It is possible to select the servo control functions/programming languages by
installing the corresponding operating system software in the Q173CPU(N)/
Q172CPU(N).
(5) It is possible to use the signals such as stroke limit signals and synchronous
encoder connected to various Motion modules for motion control by setting the
Q173CPU(N)/Q172CPU(N) as the control CPU of various motion modules
(Q172LX/Q172EX, etc.).
(6) It is possible to execute not only servo control but also DI/O input/output control
according to programs described in Motion SFC program by setting the
Q173CPU(N)/Q172CPU(N) as the control CPU of Q series PLC I/O modules
(When the Motion SFC is used as the operating system software.).
(Refer to Section 2.2 (2) for Q series PLC I/O modules that can be controlled by
Motion CPU.)
(7) It is possible to exchange a data among CPUs such as automatic refresh, as the
Q series PLC Multiple CPU system.
(8) There is no restriction for installation position of Q172LX/Q173PX(-S1)/
Q172EX(-S1) among modules controlled by Motion CPU. The installation position
of Q172EX-S2/S3 is only CPU base unit.
Set the installation position in the system settings.
(9) It is possible to change a servo program, monitor or execute JOG operation by
connecting the teaching unit (A31TU-D3
/A31TU-DN ).
(Q173CPUN-T/Q172CPUN-T only).
(10) It is possible to execute the high-resolution (262144[PLS/rev]) synchronous
control by connecting the serial absolute synchronous encoder (Q170ENC) to
Q172EX-S2/S3.
