DBX1.1 Machine function REPOS
Edge evaluation: no
Signal state 1 or Machine function REPOS is activated in JOG mode for the mode group.
edge change
0 → 1
Signal state 0 or Machine function REPOS is not activated.
edge change
1 → 0
Signal irrelevant for JOG mode is not active.
...
Application When a fault occurs when executing a part program (e.g. tool breakage), the axis is manually
example(s) 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 precise previous position using the REPOS machine
function so that the program can be continued in the automatic mode.

(If DB11, ... DBX1.6 and DB11, ... DBX1.7 are set simultaneously, it is impossible to determine
which single block type is required. In this case, the control assumes: No single block across mode
groups).

Signal(s) updated: cyclic
Signal(s) updated:
All channels are stopped.
All channels receive a start command.
Channel KS stops at the end of the block.
The channels KA receive a STOPATEND.
(comparable with DB21, ... DBX7.2 (NC stop at the block limit).)
All channels are stopped at a block limit (at some point in time).
