The Axis Safety State attribute is an 8-bit enumerated value that indicates the state
of the associated Safety Supervisor object of the device as it applies to this axis
instance. There is only one Safety Supervisor object servicing the CIP Motion
device so its state generally applies to all applicable Axis instances of the device.
This means that all instances of this object generally have the same state for this
attribute.
The two exceptions to this general state behavior are the Waiting for TUNID
with Torque Permitted (state=51) and Executing with Torque Permitted
(state=8) states that have axis specific qualification. When the Safety Supervisor
State is Waiting for TUNID with Torque Permitted, if the Axis Safety Status bit,
Safe Torque Disabled, is set, the Axis Safety State is set to Waiting for TUNID.
When the Safety Supervisor State is Executing with Torque Permitted, if the Axis
Safety Status bit, Safe Torque Disabled, is set, the Axis Safety State is Executing.

Description
0 = Undefined/Unknown (No
MotionConnection)
Undefined
No motion connection has been opened to the drive. Actual
safety state is unknown.
1 = Self-Testing Self-Testing
The safety function of drive has been initialized; all
attributes given appropriate defaults and safety faults have
been reset.
Device is performing tests to determine if it is qualified to
execute its safety function.
