Positioning Axis - Siemens SINUMERIK 840D sl Function Manual

P2: Positioning axes
11.2 Own channel, positioning axis or concurrent positioning axis
Non-dependence between channels
Independence between channels is assured by means of the following provisions:
● An active part program per channel
● Channel-specific interface signals such as
– DB21, ... DBX7.1 (NC Start)
– DB21, ... DBX7.3 (NC stop)
– DB21, ... DBX7.7 (reset)
● One feedrate override per channel
● One rapid traverse override per channel
● Channel-specific evaluation and display of alarms
● Channel-specific display, e.g. for
– Actual axis positions
– Active G commands
– Active auxiliary functions
– Current program block
● Channel-specific testing and channel-specific control of programs:
– Single block
– Dry run (DRY RUN)
– Block search
– Program test

11.2.2

Positioning axis

Positioning axes are programmed together with path axes, i.e. with the axes that are
responsible for workpiece machining.
Commands for positioning axes and path axes can be included in the same NC block. Although
they are programmed in the same NC block, the path and positioning axes are not interpolated
together and do not reach their end point simultaneously (no direct time relationship, see also
Chapter "Motion behavior and interpolation functions (Page 660)").
