• The PLC user interface indicates "Automatic" mode:
DB11 DBX6.0=1
DB11 DBX6.1=0
DB11 DBX6.2=0
DB11 DBX7.0=0
DB11 DBX7.1=0
DB11 DBX7.2=0
• In “JOG in AUTOMATIC”, the PLC user interface displays whether the mode group is in “Mode group
RESET”. This enables the NCK to now automatically switch internally to JOG, if required.
DB11 DBX6.4
DB11 DBX26.4; For mode group 2
DB11 DBX46.4; For mode group 3
• In “JOG in AUTOMATIC”, the PLC user interface displays whether the NCK has automatically switched to
“Internal JOG”.
DB11 DBX6.5
DB11 DBX26.5; For mode group 2
DB11 DBX46.5; For mode group 3
Boundary conditions
“JOG in AUTOMATIC” can only switch internally to JOG if the mode group is in “Mode group RESET” state, i.e. it
is not possible to jog immediately in the middle of a stopped program. The user can jog in this situation by
pressing the JOG key or the Reset key
in all channels
of the mode group.
Selecting AUTOMATIC disables the INC keys and the user can/must press the INC keys again to select the
desired increment. If the NCK switches to “Internal JOG”, the selected increment is retained.
If the user attempts to jog the geometry or orientation axes, the NCK switches to “Internal JOG” and the motion is
executed. Several axes can be physically moved in this way; they must all be “JOG-capable”.
Following the JOG movement, the NCK deactivates “Internal JOG” again and selects AUTO mode again. The
internal mode change is delayed until the movement is complete. This avoids unnecessary multiple switching
operations, e.g. when using the handwheel. The PLC can only rely on the “Internal JOG active” PLC signal.
The NCK will then switch to “Internal JOG” if the axis is not enabled.
