Sequence of referencing operation (AUTOMATIC mode)
1. Switch to AUTOMATIC mode.
2. Start the part program.
3. Activate follow-up mode of machine axis:
DB31, ... DBX1.4 (follow-up mode) = 0
DB31, ... DBX2.1 (servo enable) = 0
4. Take into account activation of follow-up mode:
DB31, ... DBX61.3 (follow-up mode active) = 1
5. The referencing operation is started internally in the NC as soon as part program
instruction G74 is processed.
6. External movement of machine axis across encoder zero mark or parameterized number
of distance-coded reference marks.
7. The measuring system is referenced after the encoder zero mark or the assigned number
of distance-coded reference marks have been successfully detected:
DB31, ... DBX60.4 / 60.5 (referenced/synchronized 1/2) = 1
8. The block change occurs after the referencing operation has been successfully
completed.
Aborting the reference operation
An active referencing operation can be aborted by:
• Deselecting follow-up mode
• NCK Reset
Response when measuring systems are already referenced
A measuring system that you have already referenced can be referenced again.
