Concurrent Positioning Axis - Siemens SINUMERIK Series Function Manual

10.2.3

Concurrent positioning axis

Concurrent positioning axes are positioning axes with the following properties:
● Activation from the PLC need not take place at block limits, but can be implemented at
● Program command
● The part program continues to run uninhibited, even if the concurrent positioning axis has
● An automatic axis change is possible, depending on the setting in the machine data
● With programming commands:
Activation from PLC
For SINUMERIK 840D sl, the concurrent positioning axis is activated via FC 18 from the
PLC.
● Feedrate
● Absolute dimensions (
The following functions are defined:
● Linear interpolation (
● Feedrate in mm/min or degrees/min (
● Exact stop (
● Settable zero offsets currently selected are valid
Applications
Typical applications for concurrent positioning axes include:
● Tool magazines with manual loading and unloading during machining
● Tool magazines with tool preparation during machining
