While the motion CPU (PCPU) handles the motion control
via a connected servo amp of the MR-J2S-B series
and motors of the HC-xxx series the PLC
CPU (SCPU) communicates with the programmer and the
other system modules – for example I/O modules
and special function modules of the MELSEC AnS/QnAS
series. Both CPUs share common registers and memory,
which drastically enhances efficiency and overall system
performance.
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 contol 4 (A171CPUN),
8 (A172CPUN) or even up to 32 servo axes (A173UHCPU)
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 32 axes and fast and simple connections with one-touch
bus cabling.
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
32 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.
