Ini Program (Cc_Resu_Ini.spf) - Siemens SINUMERIK 840D sl Function Manual

TE7: Continue machining at the contour (retrace support) - 840D sl only
19.5 RESU-specific part programs
If the RESU main program is created in the static user memory, the following system alarm
appears at the same time as the RESU alarm:
Alarm 6500 "NC memory full"
Note
If the number of traversing blocks generated is reduced due to insufficient memory, the entire
retraceable contour can still be retraced for retrace support. To do this, proceed as follows:
● Reverse travel up to the end of the RESU main program
● Two-time change of the interface signal:
DB21, ... DBX0.1 (Reverse/Forward)
Using the current position as a new interruption point enables RESU to generate a new RESU
main program.
Subsequently, travel is possible as far as the end of the retraceable contour range or, if the
limits have changed, as far as the starting point of the last traversing block that can be
generated.
The procedure described can be repeated as many times as required both for reverse and
forward travel.

INI program (CC_RESU_INI.SPF)

Function
The RESU-specific subprogram "CC_RESU_INI.SPF" contains the defaults required for the
reverse travel:
● Metric input system:
● Absolute dimensions:
● To switch off the adjustable zero-point offsets / frames
(see Chapter "Frames (Page 727)"):
● To switch off the active tool offsets (see Chapter "Tool
offsets (Page 727)"):
● Switching off the tool radius offset:
● Traversing velocity:
