The basic device already contains the STO safety sub-function with activation via safe inputs. Higher-level functional safety requirements can be added by inserting a CS.. safety option. Safety sub-functions of varying quality are implemented in 5 different variants.
Features:
- SIL3 according to EN 61800-5-2, EN 61508
- PL e according to EN ISO 13849-1
- Internal connection to the motor encoder, the external encoder, safe communication, and the STO
- Parameters of the safety option are included in the device data set
- Easy to replace during servicing via pluggable safety key on the safety option
- Parameterization and diagnostics using MOVISUITE® engineering software
- Process data and safety data in the same Scope recording
- Safe output for controlling functionally safe braking systems
The MOVISAFE® CS..A safety options provide further safety sub-functions according to EN IEC 61800-5-2 in addition to the STO function. The MOVISAFE® CS..A safety options and the CES11A multi-encoder card are intended to be used in the same slot and thus cannot be used simultaneously. For this reason, there are CS.31A safety options with an additional multi-encoder input.
