While up to 3 Motion CPUs control the movements via
the max. 96 connected MR-J2S-B series servo amplifiers
and HC-xxx series motors, all modules of
the System Q, including network connections, are available
to the Q CPU. The user is provided with a broad spectrum
of applications by distributing the actuation tasks
to several different CPU modules, which automatically
and cyclically exchange data via the system bus of the
base unit.
Motion controllers can tap huge performance reserves
for optimising production processes and improving product
quality.
Today, motion controller systems play
a dominant role in machine tools, printing and paper
processing machines, modern packaging machines, filling
and canning machines in the food industry, grinding,
polishing and engraving machines, X-Y-Z indexing tables
and many automation and handling systems in semiconductor
production lines.
Mitsubishi motion controllers can control 8 (Q172CPUN)
or even up to 32 servo axes (Q173CPUN) simultaneously.
The servo amplifiers communicate through
high speed synchronous communication network SSCNET
(Servo System Controller NETwork), which is a high-speed
synchronous serial communication network that delivers
better performance and more reliability than conventional
control networks. SSCNET supports batch control of up
to 96 axes and fast and simple connections with one-touch
bus cabling. The bus cycle time is only 0.8 ms.
A powerful, Windows-based programming
environment ensures a fast learning curve for new users,
despite the power and complexity of the system. The
comprehensive range of standardised software tools cuts
programming time.
All parameters and settings are configured with a standard
software package; no separate servo setup software is
required! The motion controller and its associated servo
drives and motors are also configured directly on the
computer screen.
The individual combinations of system components are
checked through automatically and any errors are signalled
immediately, thus eliminating the possibility of system
crashes!
Mitsubishi Electric’s specially-developed SFC
sequential function chart language isolates the system’s
multitasking operation from external influences. This
means drastically faster servo amp response times and
ultra-short movement cycles.
Mitsubishi motion controllers can synchronise up to
96 axes simultaneously. Programming is performed quickly
and efficiently online with a Virtual Mechanical Editor.
Mechanical master shafts, clutches and gears can be
replaced by more efficient electronic versions. And
you can forget about time-consuming text programming!
Complex mechanical processes can be solved with graphical
cam disks (CAM). The logic of the motion controller
is programmed in instruction list (IL), ladder diagram
(LD), function block diagram (FBD) or in IEC 1131.3-compatible
structured text.

A
Motion CPU cannot be operated alone in a multi CPU
system, but rather only in conjunction with a Q CPU.
