Part-program interruption

"Interrupted" status

Channel status

The STOP command is executed only if the channel concerned has the status

IS DB21, ... D35.5 ("Channel active").

STOP commands

There are various commands that stop the program execution and set the channel status to "interrupted". These

are in particular the interface signals:

DB21, ... DBX7.2 ("NC stop at the block limit)

DB21, ... DBX7.3 ("NC stop")

DB21, ... DBX7.4 ("NC stop, axes plus spindles")

DB21, ... DBX2.0 ("Single block")

Programming command "M00" or "M01".

Execution of command

After execution of the STOP command, the IS DB21, ... DBX35.3 ("Program status interrupted") is set.

Processing of the interrupted program can continue from the point of interruption with the command START.

The following actions are executed when the STOP command is triggered:

Part program execution is stopped at the next block limit (with NC stop at block limit, M00/M01 or single

block), processing is stopped immediately with the other STOP commands.

Any auxiliary functions of the current block not yet output, are no longer output.

The axes of each channel are brought to a standstill along a braking ramp and part program execution is then

The block indicator stops at the point of interruption.
