DBX7.1
Active REPOS machine function
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Machine function REPOS is active in the mode group.
Signal state 0 or
edge change
1 → 0
Machine function REPOS is not active.
Application
example(s)
When a fault occurs when executing a part program (e.g. tool breakage), the axis is manually
moved away from the fault location in the JOG mode in order to be able to replace the tool.
The axis can then be manually returned to the exact previous position using the REPOS machine
function so that the program can be continued in the automatic mode.

Active machine function REF
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Machine function REF is active in the mode group.
Signal state 0 or

DBX0.4
Activate single block
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
In AUTOMATIC and MDA modes, the operator must enable processing of each individual part
program block of the part program selected in the channel by reactivating NC START.
Signal state 0 or
edge change
1 → 0
No effect.
Special cases,
errors, ......
• In the case of active tool offset, intermediate blocks are inserted, when necessary. These blocks
must also be enabled using NC START.
• In a series of G33 blocks, a single block is only operative if "dry run feed" is selected.
• In the case of a decoding single block, calculation blocks are not processed in the single step.
