Aborting reference point approach
In axis-specific reference point approach, the machine axis is traversed in the channel that
was assigned as the master channel of the machine axis.
MD30550 $MA_ AXCONF_ASSIGN_MASTER_CHAN
Therefore, to cancel reference point approach, either a mode group reset:
DB11, ... DBX0.7 (mode group reset)
or a channel reset for the master channel of the machine axis:
DB21, ... DBB7.7 (reset)
must be initiated.
All machine axes that have not yet successfully completed reference point approach when
the action is cancelled remain in status "Not referenced":
DB31, ... DBB60.4 (referenced / synchronized 1)
DB31, ... DBB60.5 (referenced / synchronized 2)
2.2 2.2 Channel-specific 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, ... DBB0.2 (JOG mode)
DB11, ... DBB0.1 (MDA mode)
Then, select machine function REF (reference point approach):
DB11, ... DBB1.2 (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
Number Meaning
-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 are referenced simultaneously.
