These are the attributes associated with the built-in Safety functionality of an axis.
These attributes relate to the behavior of a configurable Safety Core within the
drive that executes basic drive safety functions using hardwired safety inputs and
safety outputs. These functions do not require the services of a CIP Safety network
connection. This safety functionality covers the following safety functions as
defined by IEC-61800-5-2, EN-954-1, and IEC-60204 standards:
• Safe Restart
• Safe Stop
• Safe Limited Speed
• Safe Speed Monitoring
• Safe Maximum Speed
• Safe Direction Monitoring
• Safe Door Monitoring
• Safe Door Monitoring
The Guard Status and Guard Fault attributes are defined in the axis to monitor
the behavior of built-in Drive Safety functionality. The term Guard is used for
these status attributes to differentiate these attributes from the Safety status
