9.6 Set Reference Point
Definition
With the “set reference point” job, you can synchronize the axis. The job shifts the
working range. All offsets resulting from set actual value are retained.
Requirement
• Positioning must be completed.
• You have set the parameters for the axis.
Sequence of the Job
1. Enter the value for the reference point coordinate (REFPT).
– Linear axis:
The reference-point coordinate must not be located outside the software limit
switches. This also applies to the reference point coordinate in a shifted
coordinate system.
– Rotary axis
The following rule applies to the reference point coordinate:
0 ≤ reference point coordinate < end of the rotary axis
2. Set the corresponding trigger bit (REFPT_EN).
