Parameterization - Siemens SINUMERIK 840D sl Function Manual

B3: Distributed systems - 840D sl only
3.2 NCU link
Coupled axes
Lead link axes can be used in conjunction with following axis couplings:
● Master value coupling
● Coupled motion
● Tangential tracking
● Electronic gear (ELG)
● Synchronous spindle
Requirement
The NCU must communicate via the NCU link. See Section "Link communication (Page 83)"
3.2.5.2

Parameterization

Link communication
NC-specific machine data
Number Identifier $MN_
MD12510 NCU_LINKNO
MD18780 MM_NCU_LINK_MASK.Bit 0
MD18781 NCU_LINK_CONNECTIONS
MD18782 MM_LINK_NUM_OF_MODULES
122
Meaning
Unique numerical identification of the NCU within the link group. The
identifiers must be assigned without any gaps in ascending ordering
starting from 1.
Value range: 1, 2, ... Maximum NCU number
Note:
The NCU to which the value 1 is assigned as NCU identification is the
master NCU of the link group. The parameterization of link axes and axis
containers may only be made with the machine and setting data of the
master NCU.
Activation of the link communication
Number of internal link connections
Note:
It is recommended to retain the default value 0 (determination of the
number by the NC).
Number of NCUs to be connected with one another via NCU link.
