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 and
actual value channels.
Note
With SINUMERIK 840D, this depends on the hardware/software version
up to 12 axes/spindles are permitted
up to 31 axes or 20 spindles are permitted
Reference material:
If DMP compact modules are used, then the number of axes, including DMP
modules, is limited to 31 in the axis configuration with NCU 573.3. If a DMP
compact module is used with 31-axis software, for example, then there are
30 axes available.
With the SINUMERIK 840D there are >2 channels available.
This means all the axes present on the machine. They are defined as geometry
axes or special axes.
The workpiece geometry is programmed with the geometry axes. The geometry
axes form a rectangular coordinate system (2D or 3D).
Unlike geometry axes, there is no geometrical connection for special axes,
e.g. for:
– Rotary axes
– Revolver axes
– Position-controlled spindles
The axis configuration is defined on three levels:
1. Machine level
2. Channel level
3. Program level
