Detailed Description
2.2 Channel-specific referencing
Reference Point Approach (R1)
2-4 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Simultaneous reference point approach of several machine axes
Several machine axes can be referenced simultaneously depending on the control type:
• SINUMERIK 840D: Max. 8 machine axes
• SINUMERIK 810D: Max. 5 machine axes
Start reference point approach
Channel-specific reference point approach is started with:
DB21, ... DBB1.0 (activate referencing)
The status of channel-specific reference point approach is indicated by the channel with:
DB21, ... DBB33.0 (referencing active)
Referencing status
When reference point approach is started, the referencing status of the machine axis is
reset:
DB31, ... DBB60.4 (referenced/synchronized 1)
DB31, ... DBB60.5 (referenced/synchronized 2)
Terminating reference point approach
As soon as channel-specific reference approach has been successfully completed for all
machine axes involved, this is acknowleged with:
DB21, ... DBX36.2 (all axes with obligatory reference point are referenced)
Aborting reference point approach
In channel-specific reference point approach the machine axis is traversed in the channel to
which that axis is currently assigned as channel axis.
To cancel reference point approach, either a mode group reset:
DB11, ... DBX0.7 (mode group reset)
or a channel reset for the relevant channel:
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)
