Signals To Channel (Db21 - Siemens SINUMERIK 840D sl Function Manual

DB11
DBX7.1 Active REPOS machine function
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.
