Own Channel, Positioning Axis Or Concurrent Positioning Axis - Siemens SINUMERIK Series Function Manual

Motions and interpolations
Each channel has one path interpolator and at least one axis interpolator with the following
interpolation functions:
● for path interpolator:
● for axis interpolator:
● End-of-motion criterion:
● Path axes with rapid traverse movement:
● Autonomous singleaxis operations:
● Control by PLC:

Own channel, positioning axis or concurrent positioning axis

When axes are provided for auxiliary movements on a machine tool, the required properties
will decide whether the axis is to be:
● programmed in an internal part program (see Section "Own channel - only 840D sl
● programmed in the same part program as the machining operation (see Section
● started exclusively by the PLC during machining (see Section "Concurrent positioning

Linear interpolation (
G1
If a positioning axis is programmed, an axis interpolator starts in the control (with linear
interpolation ).

The programmed end position of a positioning axis has been reached when the end-of-

Path axes can be traversed in linear or non-linear interpolation mode with rapid traverse
movement ( ).
G0
Single PLC axes, command axes started via static synchronized actions or asynchronous
reciprocating axes can be interpolated independently of the NCK.
An axis/spindle interpolated by the main run then reacts independently of the NC
program. The channel response triggered by the program run is decoupled to transfer the
control of a certain axis / spindle to the PLC.
All channel-specific signals normally act to the same extent on path and positioning axes.
Positioning axes can be controlled via additional, axis-specific signals.
PLC axes are traversed by the PLC via special function blocks in the basic program; their
movements can be asynchronous to all other axes. The travel motions are executed
separate from the path and synchronized actions.
