SoftTravelLimitNegativeAlarm
SoftTravelLimitNegativeFault
This exception condition occurs when Soft Travel Checking is
enabled and when actual position has exceeded the configured Soft
Travel Limit - Negative attribute value while commanding motion
in the negative direction.
If the Motion Exception Action for this bit is set for Stop Planner, the
faulted axis can be moved or jogged back inside the soft travel
limits. Any attempt, however, to move the axis further beyond the
Soft Travel Limit - Negative value using a motion instruction will
result in an instruction error.
For commanded axes, the Soft Travel Limit Fault can be cleared
with a Fault Reset while the axis position is beyond the Soft Travel
Limit - Negative value to allow the axis to be moved back within the
Soft Travel Limits. As long as the axis is not commanded to move
further away from the travel limit, no Soft Travel Limit Fault shall be
generated.
