572 Status Variables
Axis status conditions are prioritized from highest to lowest in the order
shown in the table. The higher the status value, the higher its priority (or
severity). This means that when a given status is active, other status
conditions of lower priority may also be active. For instance, if a
hardware overtravel fault is active for an axis, a servo output limited or
feedback OFF condition may also be active on the axis. When the highest
priority status is no longer active, Axis_status takes the value of the next
highest priority condition.
Seven of the Axis_status variable values (7 - 11, 13, 14) are fault
conditions. They are identical to the top seven Axis_fault variable values
as shown in the table below.
