9.3 Mode types and mode type change
Unique mode
The channels of a mode group operate in one mode.
A mode group is either in AUTOMATIC, JOG, or MDI mode.
Several channels of the same mode group cannot be in different modes at the same time. If individual channels
are assigned to different mode groups, a channel switchover activates the corresponding mode group. This
allows mode changes to be initiated via a channel switchover.
Modes in the mode group
The following operating modes are available:
• AUTOMATIC
Automatic processing of part programs.
- Part program test
- All channels of the mode group can be active at the same time.
• JOG in Automatic
JOG in AUTOMATIC is an extension of AUTOMATIC mode intended to simplify use. JOG can be executed
without leaving AUTOMATIC mode if boundary conditions so permit.
• JOG
Jogging (manual axis traversal)
- The axes can be traversed manually with the handwheel or the traversing keys.
- Channel­specific signals and interlocks are effective in ASUBs and when a movement is activated via IDS
synchronized actions. Links are also taken into account.
- Every channel in the mode group can be active.
• MDI
Manual Data Automatic (the NC blocks are entered via the operator panel)
- Restricted automatic execution of part programs and sections of part programs (can be only one block or a
sequence of blocks).
- Part program test
- A maximum of 1 channel per mode group can be active (applies only to TEACH IN)
- Axes can be manually traversed only in subordinate machine functions such as JOG, REPOS or TEACH
IN.
