Function Explanation Of The Q173Hcpu/Q172Hcpu Motion Cpu Modules - Mitsubishi Electric Q173HCPU User Manual

2 SYSTEM CONFIGURATION

2.1.3 Function explanation of the Q173HCPU/Q172HCPU Motion CPU modules

(1) Up to 32 axes servo amplifiers per 2 systems (up to 16 axes per 1 system) can be
used in Q173HCPU. Up to 8 axes servo amplifiers per 1 system can be used in
Q172HCPU.
(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 Q173HCPU/Q172HCPU 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 Q173HCPU/
Q172HCPU.
(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
Q173HCPU/Q172HCPU 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
Q173HCPU/Q172HCPU 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 among modules
controlled by Motion CPU. The installation position of Q172EX 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 ).
(Q173HCPU-T/Q172HCPU-T only).
(10) It is possible to execute the synchronous control corresponding to resolution
(262144[PLS/rev]) of servo amplifier (MR-J3- B) by connecting the serial
absolute synchronous encoder (Q170ENC) to Q172EX.
