9.12.3 Single block stop: inhibit according to situation

Suppress stopping in single cases

Depending on

MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (Prevent single block stop)

setting bits 0 to 12 = 1 can suppress stopping at the end of the block during the following machining processes.

Program execution must not stop after single blocks in the case of the following even if block-by-block processing

is selected:

1. An internal Asub

2. during a user ASUP

3. Subroutines with the attribute DISPLOF

4. Intermediate blocks

5. Block search group blocks

6. Init blocks

7. Blocks, which cannot be reorganized

8. Blocks, which are not repositionable

9. A repositioning block, which contains no traversing information

10.A prerun/main run/synchronization block, due to REORG

11.at a Tool selection block.

12.At a GET block

13.During a single block type 2

Sequence

If an ASUB is activated during the single block, for example, execution of the ASUB is completed. The

deceleration movement does not take place until after the end of the ASUB or the first IPO block in which single-

block suppression is not activated. If the velocity is too large for the deceleration to be performed in this block

(with continuouspath mode G64 active), G64), further block changes are allowed.

For decoding single block, MD10702 is only effective with "internal ASUB", "user ASUB" and "subroutines with

the attribute DISPLOF". In these cases, it is already clear at the time of interpretation that the block belongs to

one of the above categories. In these cases, further blocks can be generated.

SBLON in ASUB

The single block stop of an internal ASUP or user ASUP that is suppressed with MD10702

$MN_IGNORE_SINGLEBLOCK_MASK can be reactivated in ASUP by programming SBLON.

This functionality can be suppressed again with MD20117 $MC_IGNORE_SINGLEBLOCK_ASUB. The SBLON

command then becomes ineffective.
