Data block
Active mode AUTOMATIC
Signal(s) from the mode group (NCK → PLC)
Edge evaluation: No
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
AUTOMATIK mode is active.
Signal state 0 or
edge change
1 → 0
AUTOMATIK mode is not active.

DBX6.1
Active mode MDA
Edge evaluation:
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
MDA mode is active.
Signal state 0 or
edge change
1 → 0

DB11
DBX6.2
Active JOG mode
Edge evaluation: No
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
JOG mode is active.
Signal state 0 or
edge change
1 → 0
JOG mode is not active.
DB11
DBX6.3
Mode group ready
Edge evaluation: No
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
This signal is set after power on and all of the voltage have been established. The mode group is
now ready and parts programs can be executed and axes traversed in the individual channels.
Signal state 0 or
edge change
1 → 0
The mode group is not ready. Possible causes for this are:
• A critical axis or spindle alarm is present
• Hardware faults
• The mode group has been incorrectly configured (machine data)
If the mode group ready changes to signal state "0", then:
• the axis and spindle drives are braked down to standstill with the max. braking current.
• the signals from the PLC to the NCk are brought into an inactive state (cleared state).
Special cases,
errors, ......
An alarm that withdraws the interface signal
DB11 DBX6.3 (mode group ready)
ensures that all 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 be made.
