Positioning Axes (P2)

17.1
Concurrent positioning axis
If axes are available on a machine tool for auxiliary movements, they can only be triggered
from the PLC during machining operation.
Note
A positioning axis controlled by the PLC can also be an indexing axis. However, it is not
possible to control spindles in versions G/N plus and pro.
Function
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
any time in any operating mode (even when a part program is already being processed in
the channel).
●
The part program continues to run uninhibited, even if the concurrent positioning axis has
not reached the position defined by the PLC.
Activation from PLC
The concurrent positioning axis is activated via the user interface area
380x 3000 / 390x 3000 from the PLC.
●
Feedrate (with feedrate setting = 0, the feedrate is determined by the setting in the
following machine data):
MD32060 POS_AX_VELO (initial setting for positioning axis velocity)
●
Absolute dimension (G90), incremental dimension (G91),
Absolute dimension along the shortest path for rotary axes (rotary axis name =
DC(value))
The following functions are defined:
●
Linear interpolation (G01)
●
Feedrate in mm/min or degrees/min (G94)
●
Exact stop (G09)
●
Settable zero offsets currently selected are valid
