For Safe Use
Mitsubishi Electric CNC is designed and manufactured solely for applications to machine tools to be used for industrial
purposes.
Do not use this product in any applications other than those specified above, especially those which are substantially
influential on the public interest or which are expected to have significant influence on human lives or properties.
Not applicable in this manual.
 Items related to prevention of electric shocks
Do not operate the switches with wet hands. Failure to observe this caution could result in electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables. Failure to observe
this caution could result in electric shocks.
 Items related to product and manual
For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the
machine tool builder takes precedence over this manual.
Items not described in this manual must be interpreted as "not possible".
This manual is written on the assumption that all the applicable functions are included. Some of them,
however, may not be available for your NC system. Refer to the specifications issued by the machine tool
builder before use.
Some screens and functions may differ depending on each NC system (or version), and some functions may
not be possible. Please confirm the specifications before starting to use.
To protect the availability, integrity and confidentiality of the NC system against cyber-attacks including
unauthorized access, denial-of-service (DoS) (*1) attack, and computer virus from external sources via a
network, take security measures such as firewall, VPN, and anti-virus software.
(*1) Denial-of-service (DoS) refers to a type of cyber-attack that disrupts services by overloading the system or by
exploiting a vulnerability of the system.
Mitsubishi Electric assumes no responsibility for any problems caused to the NC system by any type of
cyber-attacks including DoS attack, unauthorized access and computer virus.
 Items related to connection
When using an inductive load such as relays, always contact a diode in parallel to the load as a noise
measure.
When using a capacitive load such as a lamp, always connect a protective resistor serially to the load to
suppress rush currents.
Since the analog output R registers are allocated in ascending order of channels and station numbers, the
analog output destination may change depending on added option.
 Items related to design
Always turn the spindle phase synchronization completion signal ON before chucking both ends of the
workpiece to the reference spindle and synchronized spindle. If the spindle phase synchronization signal is
turned ON when both ends of the workpiece are chucked to the reference spindle and synchronized spindle,
the chuck or workpiece could be damaged by the torsion that occurs during phase alignment.
