9.3 Mode types and mode type change

1. Before POWERON, the following machine data must be set:
MD10735 $MN_JOG_MODE_MASK, Bit 0
2. The user switches to AUTO (PLC user interface DB11 DBX0.0 = 0 → 1 edge). “JOG in AUTOMATIC” is then
active if the NCK previously had channel status “RESET” and program status “Aborted” in all mode group
channels. The axis in question must also be “jog-capable”. DRF must be deactivated (if not already
deactivated).
3. RESET is initiated or the running program is finished with M30/M2 in all mode group channels that do not have
channel status “Reset” and program status “Aborted”.
4. The relevant axis is made "Jog-capable" (e.g. axis replacement PLC → NCK).
Comment: In most applications, the axes to be traversed are “JOG-capable” and switching to AUTO will also
activate “JOG in AUTOMATIC”!
Features of JOG in AUTOMATIC
• The +/– keys cause a JOG movement, and the mode group is switched internally to JOG. (i.e. “Internal JOG”).
• Moving the handwheels causes a JOG movement, and the mode group is switched internally to JOG, unless
DRF is active.
• An ongoing JOG movement is not complete until the end position of the increment has been reached (if this
has been set) or the movement has been aborted with “Delete distance-to-go”.
In this way an increment can be stopped using Stop and then moved to the end using Start. The NCK remains
in “Internal JOG” during this time. A partial increment is possible, but it must not be interrupted using Stop.
There is a mode in which releasing the travel key causes interruption within an increment.
• Without any JOG movement, “JOG in AUTOMATIC” responds in the same way as “Automatic”. In particular,
the Start key starts the selected part program and the appropriate HMI softkey initiates a block search.
• If JOG movement is active, the NCK is internally in JOG mode, and, thus, a block search request is refused
and a Start cannot start the part program. Start starts any remaining increment or has no effect.
• While a mode group axis is being traversed in JOG mode, the mode group remains internally in JOG mode.
Comment: This phase can begin with the JOG movement of an axis and end with the end of the JOG
movement of
another
axis.
• Axis replacement is not possible for an axis with active JOG movement. (The axis might change mode group).
The NCK blocks any axis replacement attempt.
