Machine safety in Japan

The situation in Japan is different from that in Europe and the US. Legislation such as that
prescribed in Europe does not exist. Similarly, product liability does not play such an
important role as it does in the US.
Instead of legal requirements to apply standards have been defined, an administrative
recommendation to apply JIS (Japanese Industrial Standard) is in place: Japan bases its
approach on the European concept and uses basic standards as national standards (see
table).

Equipment regulations

In addition to the requirements of the guidelines and standards, company-specific
requirements must be taken into account. Large corporations in particular (e.g. automobile
manufacturers) make stringent demands regarding automation components, which are often
listed in their own equipment specifications.
Safety-related issues (e.g. operating modes, operator actions with access to hazardous
areas, EMERGENCY STOP concepts, etc.) should be clarified with customers early on so
that they can be integrated in the risk assessment/risk reduction process.

Safety Integrated function - STO
The Safe Torque Off (STO) is a safety function that prevents the drive from restarting
unexpectedly, in accordance with EN 60204-1:2006 Section 5.4.
The STO function is in conformance with the IEC 61508, SIL2 standard, in the operating
mode with a high demand, Category 3 and Performance Level d (PL d) acc. to ISO 13849-
1:2006, as well as IEC 61800-5-2.
Controlling the STO Function
The STO function can be controlled via terminals. For the details about STO wiring, refer to
the chapter "24V power supply/STO - X6 (Page 101)".
