If any issue is detected on the
dual-channel STO function
(their state is different for a
long period of time), an
abnormal fault is active can be
reported. This state avoids the
application of torque to the
motor. If this persists for > 1.4 s
~ 3.4 s the STO will lock in
FAULT state. To reset this fault
a power cycle is needed.

After >1.4 s ~ 3.4 s of abnormal
STO active, the driver will stay
in this state until the power

If a voltage out of the limits is
detected on the internal logic
voltages, the system is
conducted to a safe state,
similar to power-off. Only if the
safe logic voltages are
recovered (usually after
reparation or restart), the
system can return to any other
state.

The wiring of the recommended STO circuit is shown next.
