DB11, ... DBX0.7 (mode group reset)DB21, ... DBX7.7 (channel reset)All machine axes that have not yet successfully completed reference point approach when theaction is cancelled remain in status "Not referenced":DB31, ... DBX60.4 (referenced / synchronized 1)DB31, ... DBX60.5 (referenced / synchronized 2)15.3 Channelspecific referencingFor channel-specific referencing, all machine axes of the channel are referenced in theparameterized sequence when reference point approach is initiated.Selecting mode and machine functionBefore starting the reference point approach of the machine axes, the associated mode groupmust be switched into the JOG or MDI operating mode:DB11, ... DBX0.2 (active JOG mode)DB11, ... DBX0.1 (active MDI mode)Then machine function REF (reference point approach) must be selected:DB11, ... DBX1.2 (REF machine function)Parameterizing the axis sequenceThe following machine data element is used to specify the sequence in which the machineaxes of the channel are referenced:MD34110 $MA_REFP_CYCLE_NR = 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 will be referenced simultaneously.Simultaneous reference point approach of several machine axesSeveral machine axes can be referenced simultaneously, depending on the control:Start of reference point approachChannel-specific reference point approach is started with:DB21, ...
