GuardStopInputFault
ATTENTION: The safe torque-off fault is detected upon demand of the safe
torque-off function. After troubleshooting the STO function or performing
maintenance that might affect the STO function, the STO function must be
executed to verify correct operation.
IMPORTANT The GuardStopInputFault can be reset only if both inputs are in the OFF-
state for more than 1 second. After the fault reset requirement is satisfied,
an MAFR command in the Logix Designer application must be issued to
reset the GuardStopInputFault.

Safe Torque-off Connector Data

Two rows of eight pins are provided for making drive-to-drive connections.
The dual-axis inverters have pins designated for axis A and axis B. The single-
axis inverters do not use STO-6, -7, -8 and STO-14, -15, -16.
