Boundary conditions for standard functions

3.2.1

Axis exchange, 1st and 2nd geometry axis

As long as RESU is active, the first two geometry axes in the channel must not be
transferred to another channel via axis exchange (RELEASE(x)/GET(x)).
RESU is active:
• Start: Part program command CC_PREPRE(1)
• End: Program end or part program command CC_PREPRE(-1)
3.2.2

Channel axes

Channel axes other than the 1st and 2nd geometry axes on the channel are not affected by
RESU.
If traversing movements in other channel axes are required for retrace support and/or
reverse travel, these can either be set manually by the machine operator or programmed as
a traversing block in the RESU-specific subroutine CC_RESU_INI.SPF.
Warning
Throughout the continue machining operation in the context of the RESU technological
function, the machine operator must ensure that the associated traversing movements
remain free of collisions.
3.2.3

Block numbers

The following RESU-specific subroutines and their subroutines must not contain block
numbers:
• CC_RESU_INI.SPF
• CC_RESU_END.SPF
The following alarm appears in the event of an error:
• Alarm "75604 reverse travel not possible, error no.
Special functions: Retrace Support (TE7)
