DBX0.6 Mode group stop axes plus spindles
Edge evaluation: no
Signal state 1 or An NC stop is activated for all the channels of the mode group. The channel status of all of the
edge change active channels changes to the channel status "interrupted". All of the channels in channel status
0 → 1 "reset" remain in the channel status "reset". Programs that are running at this point are immediately
interrupted (at the earliest possible point, even within a block) and the program status changes to
"stopped". All the moving axes and spindles of the mode group are decelerated according to their
acceleration characteristics without contour violation. The program can be restarted with NC start.
Signal state 0 or Channel status and program execution are not influenced.
edge change
1 → 0
Special cases, All the axes and spindles of a mode group that are not triggered by a program or a program block
errors, ...... (e.g. axes traverse because traverse keys are pressed on the machine control panel, spindles are
controlled by the PLC) decelerate to rest with "mode group stop plus spindles".

DBX0.7 Mode group reset
Edge evaluation: yes
Signal state 1 or A reset is activated for all the channels of the mode group. All of the channels are then in the
edge change channel status "reset". All of the current programs are then in the program status "aborted". All
0 → 1 moving axes and spindles are decelerated to zero speed according to their acceleration ramp
without contour violation. The initial settings are set (e.g. for G functions). The alarms for the mode
group are cleared if they are not POWER ON alarms.
Signal state 0 or Channel status and program execution are not influenced by this signal.
edge change
1 → 0
Corresponding to .... DB21, ... DBX7.7 (channel reset)
DB11, ... DBX6.7 (all channels in the reset state)
Special cases, An alarm which cancels the interface signal
errors, ...... DB11, ... DBX6.3 (mode group ready)
ensures that all of the channels of the mode group are no longer in the reset state.
In order to switch to another operating mode, a mode group reset (DB11, ... DBX0.7) must then be
initiated.

DBX1.0 Machine function TEACH IN
Edge evaluation: no
Signal state 1 or Machine function TEACH IN is activated in JOG mode for the mode group.
edge change
0 → 1
Signal state 0 or Machine function TEACH IN is not activated.
edge change
1 → 0
Signal irrelevant for If JOG mode is not active.
