1 OVERVIEW
(c) High speed and high response processing is realizable with the step
processing method (only active steps) of Motion SFC.
(d) Not only positioning control but also numerical operations, device SET/RST,
etc. can be processed with Motion CPU side, making via PLC CPU is
unnecessary and a tact time can be shortened.
(e) By transition condition description peculiar to Motion SFC, the instructions to
servo amplifier is possible at completion of starting condition.
(f) By transition condition description peculiar to Motion SFC, after starting,
transition to next step is possible without waiting for positioning completion.
(g) Motion SFC program that responds and executes it at high speed for
interrupt input from external source can be set.
(h) Motion SFC program executed in the fixed cycle (0.88ms, 1.77ms, 3.55ms,
7.11ms, 14.2ms) by synchronizing to the Motion operation cycle can be set.
(3) High speed operation processing
(a) The minimum operation cycle of the Motion CPU is made 0.88[ms] (so far,
the ratio of 4 times), and it correspond with high frequency operation.
(b) High speed PLC control is possible by the Q series PLC CPU.

Q01CPU
(4) Connection between the Motion controller and servo amplifier with
high speed serial communication by SSCNET
High speed serial communication by SSCNET connect between the Motion
controller and servo amplifier, and batch control the charge of servo parameter,
servo monitor and test operation, etc.
It is also realised reduce the number of wires.
(5) The operating system software package for your application needs
By installing the operating system software for applications in the internal flash
memory of the Motion CPU, the Motion controller suitable for the machine can be
realized.
And, it also can correspond with the function improvement of the software
package.
(a) Conveyor assembly use (SV13)
Offer liner interpolation, circular interpolation, helical interpolation, constant-
speed control, speed control, fixed-pitch feed and etc. by the dedicated
servo instruction. Ideal for use in conveyors and assembly machines.
