9.3 Mode types and mode type change
● JOG
Manual traversing of axes via traversing keys of the machine control panel or via a
handwheel connected to the machine control panel:
– Channel-specific signals and interlocks are taken into account for motions executed by
– Couplings are taken into account.
– Every channel in the mode group can be active.
● MDI
Manual Data Automatic (the blocks are entered via the user interface)
– Restricted execution of part programs and part program sections.
– Part program test.
– A maximum of one channel per mode group can be active (applies only to TEACH
– Axes can only be traversed manually in subordinate machine functions such as JOG,
Applies to all modes
Cross-mode synchronized actions
Modal synchronized actions can be executed by means of IDS in all modes for the following
functions parallel to the channel:
● Command axis functions
● Spindle functions
● Technology cycles
Selection
The user can select the desired mode by means of softkeys on the user interface.
This selection (AUTOMATIC, MDI, or JOG) is forwarded to the PLC on the NC/PLC interface,
but is not activated:
DB11 DBX4.0, 0.1, 0.2 (strobe mode)
Activation and priorities
The mode of the mode group is activated via the NC/PLC interface:
DB11 DBX0.0, 0.1, 0.2 (mode)
If several modes are selected at the same time, the following priority applies:
Priority
1st priority, high
2nd priority, medium
3rd priority, low
