(7) Changes can be made to the operating system (OS).
A comprehensive range of software packages is available to suit all
applications, and the applicable OS can be written directly to the CPU built-in
Flash memory to realize a motion controller suitable for any machine.
Furthermore, functional upgrades to software packages are also possible.
1) SV13 for conveyance and assembly
SV13 can perform tasks such as 1 to 4-axis linear interpolation with
dedicated servo commands, 2-axis circular interpolation, 3-axis helical
interpolation, CP control (constant speed control), speed control, and
fixed-pitch feeding, making it ideal for equipment such as conveyors and
assembly machines.
2) SV22 for automatic machines
Multiple servo motors can be controlled simultaneously with a mechanical
support language, and cam control is possible using software, making
SV22 ideal for automatic machines and so on.
Motion controllers come preinstalled with SV22 when shipped.
Furthermore, the latest versions of the OS software for all motion controllers
can be downloaded from the Mitsubishi Electric FA site and then installed.
(8) Mechanical support language (mechanical system program): valid only
for SV22
In the past, synchronous motion and cooperative motion were required for
industrial equipment and automatic machines, and these motions were
combined as an implementation tool.
This method used transfer mechanisms such as main shafts, which were the
driving forces, and gears, clutches, and cranks to drive output mechanisms
such as rotational motions, linear motions, reciprocating motions, and feed
motions,. This method was excellent in terms of synchronous and cooperative
motions, but was lacking in flexibility.
Separating the mechanical support language from the previous mechanical
combination, and using software to process machine mechanism motions has
led to improvements in the functionality and performance of the positioning
control used to control servo motors, and because this is an electrical method,
there are few mechanical limitations, facilitating a logical design.
Transfer mechanisms from main shafts to gears, clutches, transmissions, and
differential gears, and output mechanisms such as roller output, ballscrew
output, rotary table output, and cam output are shown in diagrams on
peripheral equipment screens, and simply by setting the respective module
parameters, synchronous and cooperative motions can be realized, facilitating
the easy construction of flexible control systems.
Consequently, mechanical parts such as main shafts, gears, clutches, cranks,
transmissions, differential gears, and cams can be significantly eliminated or
omitted, meaning lower costs and less wear.
(9) Software cam: valid only for SV22
By replacing the cam mechanism for which synchronous control was being
performed mechanically with software, and then setting synchronous control
parameters, the following features can be obtained by synchronizing control
with input axes.
1) Cam curved line data can be created easily with cam curved line creation
software, eliminating the need to manufacture cam parts.
2) Cams can be replaced easily by changing the cam No. from the motion
SFC program or sequence program.
3) There is no need to consider the wear or short life characteristic of cams.
