Machining is stopped after loading of the last action block after block search, the NC/
PLC interface signal DB3300 DBX0.6 (last action block active) is set and alarm 10208
is output.
Bit 0 = 1:
Machining is stopped with the loading of the last action block after block search, and
the NC/PLC interface signal DB3300 DBX0.6 (last action block active) is set. Alarm
10208 is not output until the PLC requests it by setting the NC/PLC interface signal
DB3200 DBX1.6 (PLC action finished).
Application:
Starting an ASUB from the PLC after block search.
The message to the operator that another NC start is required in order to continue with
the program is not to be displayed until after the end of the ASUB.
Bit 1 = 1
Automatic ASUB start after output of the action blocks. Alarm 10208 is not output until
the ASUB has finished.
Bit 2 = 0:
Spindle: auxiliary functions are output in the action blocks.
Bit 2 = 1:
The output of the auxiliary functions in the action blocks is suppressed. The spindle
programming collected by block search can be output at a later point in time (e.g. in
an ASUB).
The program data for this are stored in the following system variables:
- $P_SEARCH_S,
- $P_SEARCH_SDIR,
- $P_SEARCH_SGEAR,
- $P_SEARCH_SPOS,
- $P_SEARCH_SPOSMODE
Bit 3 = 1:
The cascaded search run is disabled (default setting: release).
Cascaded search run means that the search run is restarted immediately after finding
a search target.
Bit 4:
Bit 5 = 0:
Bit 5 = 1:
During block search to a nibbling block, a punching stroke is triggered at block start
(1st nibbling stroke).
Bit 6 = 0:
Bit 6 = 1:
With block search, calculation is made with simple, computing-time-optimized
algorithms.
Bit 7 = 0:
Any adjustment movements that may be necessary on activation of a tangential axis
coupling, during or after an SSL, are performed with the feed conditions active in the
activation block (G0 or G1 with feedrate). In the case of G1, the feedrate can
additionally be set in SD 42121: $SC_AX_ADJUST_FEED.
Bit 7 = 1:
The adjustment movements necessary on activation of a tangential axis coupling, during
or after an SSL, are always performed with rapid traverse feedrate (G0). In this case,
the feedrate value in SD 42121: $SC_AX_ADJUST_FEED is ignored.
