Channel­specific Referencing - Siemens SINUMERIK 828D Function Manual

15.3 Channel­specific referencing
In channel-specific reference point approach, all machine axes of the channel are referenced in the
parameterized sequence when reference point appraoch is initiated.
Selecting mode and machine function
Before starting reference point approach of the machine axes, you must first set the mode group to JOG or MDA
mode:
DB11, ... DBX0.2 (active JOG mode)
DB11, ... DBX0.1 (active MDA mode)
Then machine function REF (reference point approach) must be selected:
DB11, ... DBX1.2 (REF machine function)
Parameterizing the axis sequence
The following machine data element is used to specify the sequence in which the machine axes of the channel
are referenced:
MD34110 $MA_REFP_CYCLE_NR =
Number Description
-1 The machine axis does not have to be referenced for NC START in the channel.
0 The machine axis does not participate in channel-specific reference point approach.
1 - 15 Sequence number in channel-specific reference point approach.
The machine axes are referenced in ascending order of numbers.
Machine axes with the same number will be referenced simultaneously.
Simultaneous reference point approach of several machine axes
Several machine axes can be referenced simultaneously, depending on the control:

Start of reference point approach
Channel-specific reference point approach is started with:
DB21, ... DBX1.0 (activate referencing)
The status of channel-specific reference point approach is indicated by the channel with:
DB21, ... DBX33.0 (activate referencing)
