• Tangential follow-up of individual axes
• Superimposed motion interpolation
• Travel to fixed stop
• Synchronous spindle grouping
On reaching the beginning of the target block (see "Time sequence of SERUPRO" below),
the user can activate a SERUPRO ASUB.
Special points should be noted during SERUPRO ASUB with regard to:
• Reference point approach
• Tool management
• Spindle ramp-up
Other functions after search target was found, such as:
• Continue machining after SERUPRO search target found (REPOS offset)
• Repositioning on contour with controlled REPOS
• Part program expansions for SERUPRO
Activation
SERUPRO is activated via the HMI. SERUPRO is operated using the "Prog. Test Contour"
softkey.
SERUPRO uses REPOS to approach the target block.
Chronological sequence of SERUPRO
1. The "Prog. Test Contour" softkey and the search target are operated via the HMI.
2. The NC now automatically starts the selected program in "Program test" mode.
– In this mode, axes are not traversed.
– Auxiliary functions $A_OUT and the direct PLC IO are output.
– The auxiliary functions of the target block are not output.
3. Numerous operator actions are permitted during this phase:
– Start, Stop
– Axis replacement
– Deletion of distance-to-go
– Mode change, ASUBs, etc.
The program and channel statuses of interface signal:
DB21, ... DBB35
or system variable:
$AC_PROG
is supplied analogous to real operation.
