Safety
Use of safety functions
NOTICE!
The safety sub-functions STO and SBC are already available on the CMMT-AS on delivery without the
need for any additional parameterisation. Prior to initial commissioning, you must – as a minimum –
wire safety sub-functions STO and SBC.
1. Make sure that each safety function of the system is analysed and validated. It is the responsibil-
ity of the operator to determine and verify the required safety classification (safety integrity level,
performance level and category) of the system.
2. Put the servo drive into operation and validate its behaviour in a test run.
During integration of the PDS, observe the measures stipulated by standard EN ISO 13849-1 chapter
G.4:
–
Functional test
–
Project management
–
Documentation
–
Performance of a black-box test
6.2
Check lists
The safety functions must be validated after installation and after every modification to the installa-
tion. This validation must be documented by the person who commissions the device. To assist you
with commissioning, we have put together some sample questions for risk reduction in the form of the
check lists below.
The following check lists are no substitute for safety training. No guarantee can be provided for the
completeness of the check lists.
No.
Question
Relevant
Done
