<Dist>: Reference to a vector.
Input: Incremental traversing distance
● <Dist> [0]: 1st geometry axis
● <Dist> [1]: 2nd geometry axis
● <Dist> [2]: 3rd geometry axis
Output (only for set hundred thousands digit in <Status>):
<Dist> contains a unit vector v as output value which defines the further tra‐
versing direction in the WCS.
Case 1: Formation of vector v for <TestID>, bit 4 == 1
The input vectors <Dist> and <MaxDist> span the motion plane. This plane is
cut by the violated limitation surface. The intersecting line of the two planes
defines the direction of vector v.The orientation (sign) is selected so that the
angle between the input vector <MaxDist> and v is not greater than 90 de‐
grees.
Case 2: Formation of vector v for <TestID>, bit 5 == 1
Vector v is the unit vector in the projection direction of the traversing vector
contained in <Dist> on the limitation surface. If the projection of the traversing
vector on the limitation surface is the zero vector, an error is returned.
Parameter type: Input/output
Data type: VAR REAL [3]
Value range: -max. REAL value ≤ x[<n>] ≤ +max. REAL value
<Limit>: Reference to an array of length 5.
● <Limit> [0 - 2]: Minimum clearance of the geometry axes to the limits:
– <Limit> [0]: 1st geometry axis
– <Limit> [1]: 2nd geometry axis
– <Limit> [2]: 3rd geometry axis
The minimum clearances are observed with:
– Working area limitation: No restrictions
– Software limit switches: If no transformation is active, or a transformation is
active in which a clear assignment of the geometry axes to the linear ma‐
chine axes is possible, e.g. 5-axis transformations.
● <Limit> [3]: Contains the minimum clearance for linear machine axes which, for
example, cannot be assigned a geometry axis because of a non-linear trans‐
formation. This value is also used as limit value for the monitoring of the con‐
ventional protection zones and the collision avoidance protection zones.
● <Limit> [4]: Contains the minimum clearance for rotary machine axes which, for
example, cannot be assigned a geometry axis because of a non-linear trans‐
formation.
Note
This value is only active for the monitoring of the software limit switches for
special transformations.
