Reference Points; System Variables For Path Interpolation And Transformation On The Path Object - Siemens SIMOTION Function Manual

2.13.2.2

Reference points

The following reference points are used in path interpolation:
● Cartesian zero point
● Kinematic zero point
● Kinematic end point
The path object calculates the position on the path. This is also the kinematic end point.

System variables for path interpolation and transformation on the path object

Figure 2-28
The position values and dynamic values can be accessed via a system variable:
Path data
System variables
path.acceleration
path.command
path.dynamicAdaption
path.length
