■ Standard Models (CIMR-LA)
Table D.11 Safety Standards and Applicable Harmonized Standards for CIMR-LA
■ Models in Compliance with IEC/EN 61508 SIL3 (CIMR-LF)
Table D.12 Safety Standards and Applicable Harmonized Standards for CIMR-LF
The Safe Disable function is in compliance with these standards.
◆ Specifications
The Safe Disable inputs provide a stop function in compliance with “Safe Torque Off” as defined in the IEC/EN
61800-5-2. Safe Disable inputs have been designed to meet the requirements of the ISO/EN 13849-1 and IEC/EN 61508.
A Safe Disable Status Monitor for error detection in the safety circuit is also provided.
