Configuration Of A Multi-Spindle Turning Machine - Siemens SINUMERIK Series Function Manual

B3: Distributed systems - 840D sl only
2.3 Examples
Example 3.3 Use internal wait
AXCTSWE(CTL) ; If an axis container is reenabled for rotation,
; an internal wait takes place for the end of the earlier
; axis container rotation.
N2150 WHILE (rl == $AN_AXCTAS[ctl])
Note
Programming in the NC program:
WHILE ($AN_AXCTSWA[n] == 0)
ENDWHILE
cannot be used as a reliable method of determining whether an earlier axis container rotation
has finished. Although in software version 7.x and later, $AN_AXCTSWA performs an
implicit preprocessing stop, this type of programming cannot be used, as the block can be
interrupted by a reorganization. The system variable then returns "0" as the axis container
rotation is then ended.

Configuration of a multi-spindle turning machine

Introduction
The following example describes the use of:
● Several NCUs in the NCU link group
● Flexible configuration with axis containers
Machine description
● Distributed on the circumference of a drum A (front-plane machining) the machine has:
126
– 4 main spindles, HS1 to HS4
Each main spindle has the possibility of material feed (bars, hydraulic bar feed, axes:
STN1 - STN4).
– 4 cross slides
– Each slide has two axes.
– Optionally a powered tool S1-S4 can operate on each slide.
