(1) For the use of our Motion controller, its applications should be those that may not result in a serious damage
even if any failure or malfunction occurs in Motion controller, and a backup or fail-safe function should operate
on an external system to Motion controller when any failure or malfunction occurs.

Therefore, applications substantially influential on the public interest for such as atomic power plants and other
power plants of electric power companies, and also which require a special quality assurance system, including
applications for railway companies and government or public offices are not recommended, and we assume no
responsibility for any failure caused by these applications when used.
In addition, applications which may be substantially influential to human lives or properties for such as airlines,
medical treatments, railway service, incineration and fuel systems, man-operated material handling equipment,
entertainment machines, safety machines, etc. are not recommended, and we assume no responsibility for any
failure caused by these applications when used.
We will review the acceptability of the abovementioned applications, if you agree not to require a specific quality
for a specific application. Please contact us for consultation.
