Insert main run blocks between the assignments if the program sequence allows. See
also $A_LINK_TRANS_RATE.
Clear alarm with the Delete key or NC START.
NCU link cannot transfer all link variables
A value assignment to a link variable (e.g. $a_dld[16]=19) is performed in the main run
and transferred via NCU link to all NCUs in the link network. The bandwidth of this con-
nection restricts the number of value assignments which can be transferred in one inter-
polation cycle. Assignment operations which are not transferred are stored in a buffer
memory. This buffer is full!
All value assignments are combined in the next main run block and performed immedi-
ately this block is executed.
A main run block is the block at which you would stop in single block mode SLB1.
Examples: Blocks with a real traversing movement (G0 X100), Stopre, G4, WAITM,
WAITE,...
Link variable scanning operations are not affected (e.g.: R100= $a_dld[16])
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Insert main run blocks which require a sufficient number of interpolation cycles for execu-
tion (e.g. G4 F10) between the assignments. A block with an additional preprocessor stop
does not improve the situation! See also $A_LINK_TRANS_RATE, for a variable which
you can test before an assignment.
Clear alarm with the RESET key. Restart part program.
NCU link is heavily loaded, impending memory shortage
Informational alarm for NC program developer.
The capacity of the NCU link is not large enough to transfer all the data. This non-cyclic
data includes link variable assignments, machine data write operations, values for con-
tainer switches and setting data write operations.
This type of data is buffered and is not lost. The buffer memory is now 70% full.
- Alarm display.
- Warning display.
The timing of cyclic data should not be distorted in the NC program.
Clear alarm with the Delete key or NC START.
Machine data matching via NCU link not complete
A non-released option has been used in the block.
- NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Change less setting or machine data at the same time.
Switch control OFF - ON.
