Reposition is an internal procedure that is needed for mode change after JOG/
JOGREF..., switch skip block on and off, activate machine data, axis replacement,
switch on overstore, switch on single block, switch dry run feedrate on and off,
subroutine level cancelation, and possibly user ASUBs. Reposition is never needed in
Reset state.
Example blocks in which reposition is impossible:
- G33 + blocks in which reorganize is impossible.
Bit8 = 1
Means that there is no stop in a residual block that does not contain traversing
information.
Bit9 = 1
Means that there is no stop in a run in/main run synchronization block (e.g.STOPRE,
$Variable) that is repeated because of an interruption with Reorg (e.g. mode change).
Bit10= 1
Means that there is no stop in a "tool selection block". "Tool selection block" only
occurs
with tool
management (magazine management or TMMG) active. This block gives the
corresponding tool change command to the PLC.
This block is generally generated by T programming from the part program.
Example block "N1010 T="Drill" M6 D1"
Bit11= 1
The control has to automatically generate implicit GET blocks for the axis replacement
function (axis replacement: 2 or more channels control one axis alternately) if no
explicit GET(D) has been programmed and the following block wants to traverse the
axis. (The other channel had previously used this axis).
An explicitly programmed GET may appear as follows "getd(x1,y1,z1) or get(x1,y1,z1)".
There is no stop at explicit or implicit GET blocks in the single block with this bit
11.
Bit12= 1
There is no stop in the single block type 2 in the SBLON block.
Bit13= 1
If an axis is pulled out in the middle of a block and possibly assigned to another
channel,
then
there
is no stop at the PREMATURE end of this block. This block follows
a REPOSA in order to traverse it to the end, there is no stop until this end has been
reached.
Bit14=1
In a part program line, in which a substitution subroutine is called due to NC language
replacement, only one stop is performed under the condition that the subroutine
includes PROC attribute SBLOF. It is irrelevant whether the subroutine is called at
block start and/or end or whether it is exited with M17 or RET.
Bit15=1
Means that there is no stop in any user ASUB block. Exception: The single block stop
has been explicitly activated via the SBLON command.
There are three different internal ASUBs that are triggered by different events.
- Repos: In the case of the events: change of operating mode to a manual mode (JOG,
JOGREF,...)
unless MODESWITCH_MASK
is not set, switch skip block on and off, activate
machine data, switch-on overstore, axis replacement, subroutine level cancelation,
switch-on single block, switch dry run feedrate on and off, alarm with compensation
block.
- Return: Delete distance-to-go, switchover after TEACH-IN (if available), or
deselection of MDI with corresponding MODESWITCH_MASK.
Bit16=1
Activating SERUPRO (search run via prog test) prevents stopping at single blocks.
