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.

Application exam‐ When a fault occurs when executing a part program (e.g. tool breakage), the axis is manually moved
ple(s) 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.

DBX1.2 Machine function REF
Edge evaluation: No
Signal state 1 or Machine function REF is activated in the JOG mode for the mode group.
edge change
0 → 1
Signal state 0 or Machine function REF is not activated.
edge change

DBX1.6 Single block type B
Edge evaluation: No
Signal state 1 or Bit set and DB11 DBX1.7 not set: Response across modes
edge change
● All channels are stopped.
0 → 1
● All channels receive a start command.
● Channel KS stops at the end of the block.
● The channels KA receive a STOPATEND.
● All channels are stopped at a block limit (at some point in time).
(If DB11 DBX1.6 and DB11 DBX1.7 are set simultaneously, it is impossible to determine which single
block type is required. The control then assumes: No single block across mode groups).
Signal state 0 or If Bit DB11 DBX1.6 is not set and Bit DB11 DBX1.7 is set, then it is single block type A.
edge change
(If DB11 DBX1.6 and DB11 DBX1.7 are not set, it is impossible to determine which single block type
