One CNC CPU module up to 7 part systems and 16 axes.
Up to two CNC CPU modules can be installed on iQ Plat-
form.
Multi-axis, Multi-part System Control
Sequence processing time is widely accelerated, including
3.5 times faster basic instruction performance compared to
our conventional one.
Reduced scan time also reduces the tact time.

For data transfer between CNC CPUs and PLC CPUs, we
have newly developed a dedicated high-speed bus. Data
are transferred at a high-speed cycle (0.88ms) between
the high-speed shared memories of each CPU, so each
CPU speed can be fully utilized.
Ultrahigh-speed network between CNC CPUs and PLC CPUs
This function enables safety signal comparison, speed obser-
vation and duplexed emergency stop. This function complies
with the European safety standard EN ISO 13849-1 PL d.
Customized screens can be easily developed with the GOT
Screen Design Software (GT Works3). It is possible to
operate a machine via a touch panel instead of a
conventional machine operation panel.
NC Monitor is installed in SVGA and XGA models as
standard, which enables setting of each NC data and editing
of machining programs, etc.
