STO Fault Reset

To clear the STO Fault condition, a transition from logic 0 to 1 of the
SO.Reset tag is required after the SO.SafeTorqueOff tag has transitioned from
logic 0 to 1 (see Table 164
If the Kinetix 5700 servo drive safety controller detects a fault, the input
assembly tag SI.SafetyFault is set to 1.
To reset Axis.SafetyFault, an MAFR command must be issued.
IMPORTANT Transition of the SO.SafeTorqueOff tag to logic 1 must always be executed
prior to transition of the SO.Reset tag to logic 1.
IMPORTANT All Kinetix 5700 inverter axes enter the faulted state if any STO function
fault is detected. Refer to
troubleshooting.
Refer to Figure 156 for an understanding of the Kinetix 5700 STO state restart
functionality.
