4.6.1

Rapid lift with G10.6

A retraction position for the rapid lifting of a tool can be activated with G10.6 <Axis position>
(e.g., in case of tool breakage). The retraction motion itself is started with a digital signal.
The 2nd rapid input of NC is used as the start signal.
Another rapid input (1-8) can also be selected with machine data 10820
$MN_EXTERN_INTERRUPT_NUM_RETRAC (1 - 8).
The interrupt program (ASUB) CYCLE3106.spf must always be available for the rapid
retraction with G10.6. If the CYCLE3106.spf is not available in the part program memory, the
Alarm 14011 "Program CYCLE3106 not available or not released for processing" is output
with G10.6 in a part program block.
The response of the control system after the rapid retraction is defined in ASUB
CYCLE3106.spf. If the axes and the spindle are stopped after the rapid retraction, M0 and
M5 must be programmed in CYCLE3106.spf. If CYCLE3106.spf is a dummy program that
contains only M17, the part program is continued without any interruption after the rapid
retraction.
If the rapid retraction is activated with the programming G10.6 <Axis position>, then the
change in the input signal of the 2nd NC rapid input from 0 to 1 aborts the current movement
and the position programmed in the G10.6 block is moved at rapid traverse. Here, the
positions are approached as absolute or incremental, as programmed in the G10.6 block.
The function is deactivated with G10.6 (without position specification). Rapid retraction via
the input signal of the 2nd rapid NC input is blocked.
Restrictions
Only one axis can be programmed for rapid retraction.
4.6.2

Measuring with "delete distance-to-go" (G31)

Measuring with "Delete distance-to-go possible" is activated by specifying "G31 X... Y... Z...
F... ;". The linear interpolation is interrupted and the distance-to-go of the axes is deleted if,
during the linear interpolation, the measurement input of the 1st probe is active. The program
is continued with the next block.
Format
G31 X... Y... Z... F... ;
G31: Non-modal G function (operates only in the block in which it is programmed)
