Axis configuration
1. Machine level
6-108
The SINUMERIK 840D is supplied as standard with the following configuration:
S
NCU 571: 1 channel and 5 axes.
S
NCU 572/573: 2 channels and 8 axes with simulated setpoint or
actual value channel.
> 2 channels are provided on the SINUMERIK 840D.
Machine axes are all axes existing on the machine. They are defined as geom-
etry axes or additional axes.
The workpiece geometry is programmed with the geometry axes. The geometry
axes form a rectangular coordinate system (2D or 3D).
In contrast to geometry axes, there is no geometric relationship between special
axes such as:
– rotary axes
– turret axes
– position-controlled spindles
The axis configuration is defined on 3 levels:
1. Machine level
2. Channel level
3. Program level
MD 10000: AXCONF_MACHAX_NAME_TAB
An axis name is defined here for each machine axis in
MD 10000: AXCONF_MACHAX_NAME_TAB.
