2.8 Referencing in followup mode
Basic logic functions: Reference Point Approach (R1)
50 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Sequence
1. Initial situation: Neither of the measuring systems are referenced:
DB31, ... DBX60.4 = 0 (referenced / synchronized 1)
DB31, ... DBX60.5 = 0 (referenced / synchronized 2)
2. Reference the indirect measuring system according to the measuring system type:
DB31, ... DBX60.4 = 1 (referenced / synchronized 1)
DB31, ... DBX60.5 = 0 (referenced / synchronized 2)
3. Traverse the machine axis across the parameterized number of reference marks.
This automatically references the direct measuring system:
DB31, ... DBX60.4 = 1 (referenced / synchronized 1)
DB31, ... DBX60.5 = 1 (referenced / synchronized 2)
2.8 Referencing in followup mode
Function
Incremental measuring systems and measuring systems with distance-coded reference
marks can be referenced even when the machine axis is in follow-up mode. This requires
that reference point approach be properly parameterized according to the measuring system
in use (see "Referencing with incremental measuring systems" and "Referencing with
distance-coded reference marks").
When referencing in follow-up mode the machine axis is moved not by the NC but by means
of an external travel movement over the encoder zero mark and the parameterized number
of distance-coded reference marks. The measuring system is referenced when the encoder
zero mark or parameterized number of distance-coded reference marks are detected.
Note
Reproducibility of the referencing result
In NC-guided reference point approach, reproducibility of the referencing result is ensured
through adherence to the assigned traverse velocities during the referencing operation.
During referencing in follow-up mode, responsibility for achieving reproducibility of the
referencing results lies with the machine manufacturer / user.
