3.0 Risk Assessment & Responsibility of the Installer
The STO feature of the
Accelnet & Stepnet Plus Panel
drives is capable of the safety integrity level (SIL) and
category/performance level (PL) stated in this manual and operates in accordance with the characteristics and
limitations described herein. But it must be noted that the drive STO function is intended to be used only as one
element of an overall safety chain and is not a complete safety function unto itself. Therefore the suitability for use
of the
Accelnet & Stepnet Plus Panel
drives in a given application must be determined in part by one or more risk
assessments of the overall safety of the end machine conducted in accordance with the applicable standards.
Such risk assessments normally consist of a thorough review of overall machine operation to identify potential
hazards. For each identified hazard, typical risk assessments take into account the severity of any potential injury
resulting from the hazard, the frequency of exposure of persons to the hazard and the probability that persons are
able to avoid the hazard if it were to occur. The machine designer is solely responsible for conducting any
necessary risk assessments and for the ultimate determination as to the suitability of the
Accelnet & Stepnet Plus
Panel
drives and the STO function for use in realizing a given overall safety function.
The installer should be experienced in motion control and functional safety.
