Unique mode
The channels of a mode group operate in one mode.
A mode group is either in AUTOMATIC, JOG, or MDA 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 implicitly.
Modes in the mode group
The following operating modes are available:
• AUTOMATIC
• JOG in Automatic
• JOG

group's readiness to operate:
DB11, ... DBX6.7 = 1 (all channels in Reset state)
DB11, ... DBX6.3 = 1 (mode group ready)
Automatic processing of part programs.
– Part program test
– All channels of the mode group can be active at the same time.
JOG in AUTOMATIC is an extension of AUTOMATIC mode intended to simplify use. JOG
can be executed without leaving AUTOMATIC mode if supplementary conditions so
permit.
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.
