Chapter 9 Kinetix 5700 Safe Torque-off Function
Table 164 - STO Tag Name Changes in the Logix Designer Application
The SO.Command tags are sent from the GuardLogix safety output assembly
to the Kinetix 5700 safety output assembly to control the safe torque-off
function.
The SI.Status tags are sent from the Kinetix 5700 inverter to the GuardLogix
safety input assembly and indicate the Kinetix 5700 safety control status.
The SI.ConnectionStatus tags indicate the safety input connection status.
Table 165
and Table 166 list the safety tags added to the controller tags when a
Kinetix 5700 servo drive is added to a GuardLogix I/O Configuration and the
connection is configured for Motion and Safety or Safety Only.
The attribute values listed are the Assembly Object attribute values.
