(7) Operating system (OS) can be changed
Software packages to match applications are available, and by directly writing the
optical OS (refer to comparison table in section 2.1) into the CPU's built-in flash
memory, a motion controller matching each machine can be created.
This system is also compatible with software package function upgrades.
1) SV13 for transfer assembly
Using the dedicated servo commands, 1 to 4-axis linear interpolation, 2-axis
circular interpolation, 3-axis helical interpolation, CP control (uniform speed
control), speed control and position follow-up control can be carried out,
making this system suitable for applications such as transfer machines and
assembly machines.
Order control is enabled with SFC.
2) SV22 for automatic machine
Multiple servomotors can be simultaneously controlled with the mechanical
support language, and cam control can be carried out with the software. This
is suitable for applications such as automatic machines.
(8) Software cam ... Valid only with SV22
When the cam mechanism, often used in machine mechanisms is replaced with a
virtual mode cam for servomotor control, the following features can be realized.
1) Cam curve data can be created easily with the cam curve creation software
package, thereby eliminating the need to manufacture cam parts.
2) The cam can be replaced easily by changing the cam No. in the motion SFC
program.
3) There is no need to consider wear and life unique to the cam.
(9) Mechanism support language (Mechanism program) ... Valid only with SV22
Conventionally, synchronous operation and coordinated operation were required
for industrial machines and automatic machines, and as a means to achieve this,
each operation was mechanically connected.
With this method, the output mechanisms such as the rotation operation, linear
operation, reciprocating operation and feed operation, are operated from the main
shaft, which is the drive source, using a conveyance mechanism such as gears, a
clutch or crank. Although accurate synchronization operation and coordinate
operations are possible, this method lacks flexibility.
The mechanical support language frees the system from the conventional
mechanical connection, and allows the positioning control functions and
performance to be improved because the servomotor is controlled by processing
the machine mechanism movements with software. At the same time, this is an
electrical method, so there are few limitations to the mechanism and rational
designs can be made.
The system from the main shaft to the conveyance mechanism such as the gears,
clutch, reduction gears or differential gears, to the output mechanism such as the
roller output, ball screw output, rotary table output or cam output are described
with figures on the peripheral device screen. Just by setting each module
parameter, the synchronized operation and coordinate operation can be realized
and a flexible control system can be easily structured.
Thus, machine parts such as the main shaft, gears, clutch, crank, reduction gears,
differential gears and cam can be greatly reduced or omitted, allowing costs to be
reduced and wear to be eliminated.
