DBX7.3 NC STOP
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change

AUTOMATIC or MDA mode:
Processing of the part program active in the channel is stopped.
The axes (not spindles) are brought to a standstill within the assigned acceleration parameters.
• Program status: stopped
• Channel status: interrupted
JOG mode:
In JOG mode, incompletely traversed incremental paths (INC...) are retracted at the next NC
START.
Note
The signal must be present for at least one PLC cycle (OB1).

DBX7.7 Reset
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The channel is reset. The initial settings are set (e.g. G functions).
The alarms for the channel are cleared if they are not POWER ON alarms.
The reset signal must be issued by the PLC (e.g., using a logic operation with the reset key on the
MCP). The signal is only evaluated by the selected channel.
The program status changes to "Aborted", and the channel status changes to "Channel status
reset".
