12.12.5 Influence of the modes on the path dimension function from the PLC
• Software limit switch (SW-L):
The following effects occur:
SW-L
SW-L
SW-L
SW-L
The path dimension is traversed
The path dimension is not traversed
and aborted
The path dimension is not traversed
and aborted
The path dimension is traversed
1.
2.
3.
4.
• Transformation
Requirement: Transformation is selected and active.
The following conditions apply:
1. Fictitious axis as a path dimension axis
The path dimension axis is transformed into a real axis and traversed.
2. Real axis as a path dimension axis
The real axis is not traversed.
The path dimension function is aborted and a negative acknowledgement is sent to the
PLC.
If the transformation is not selected and not active and the path dimension axis is a
fictitious axis, the path dimension function is aborted.
Delete distance to go has no effect.
In-process measurement is not possible.
• Coupled motion
Requirement: Coupled motion is selected and active.
The following conditions apply:
1. Leading axis as the path dimension axis:
The coupled-motion axes traverse with the leading axis.
2. Coupled-motion axis as the path dimension axis:
Coupled-motion axes are not traversed.
Path dimension is aborted and a negative acknowledgement is sent to the PLC.
