(Part 2) Note
If several limits are violated simultaneously, the limit with the greatest restriction on
the specified traversing distance is signaled.

-8 ≤ x ≤ 100000
Meaning
The distance can be traversed completely.
At least one component is negative in <Limit>.
Error in a transformation calculation.
Example: The traversing distance passes through a singularity
so that the axis positions cannot be defined.
The specified traversing distance <Dist> and the maximum
possible traversing distance <MaxDist> are linearly dependent.
Note
Can only occur in conjunction with <TestLim>, bit 4 == 1.
The projection of the traversing direction contained in <Dist>
on to the limitation surface is the zero vector, or the traversing
direction is perpendicular to the violated limitation surface.
Note
Can only occur in conjunction with <TestLim>, bit 5 == 1.
In <TestLim>, bit 4 == 1 AND bit 5 == 1
At least one machine axis that has to be considered for check‐
ing the traversing limits has not been homed.
Collision avoidance function: Invalid definition of the kinematic
chain or the protection zones.
Collision avoidance function: This command cannot be execu‐
ted because of insufficient memory.
Units digit
Software limit switches are limiting the traversing distance
Working area limits are limiting the traversing distance
Protection zones are limiting the traversing distance
Tens digit
The initial value violates the limit
The specified straight line violates the limit.
This value is also returned if the end point does not violate any
limit itself, but the path from the starting point to the end point
would cause a limit value to be violated (e.g. by passing through
a protection zone, curved software limit switches in the WCS
for non-linear transformations, e.g. transmit).
