Programmable Parameter Set Changeover (Scpara) - Siemens SINUMERIK 840D sl Programming Manual

3.15.7

Programmable parameter set changeover (SCPARA)

The changeover to a specific parameter set can be requested for an axis using the SCPARA
command.
Note
No parameter set changeover during thread cutting
During thread cutting G33 and tapping G331/G332, the parameter set is selected by the control
and cannot be changed.
Disabled parameter set changeover
A parameter set changeover can also be requested via the NC/PLC interface. In order to avoid
changeover conflicts, the parameter set changeover of the NC (SCPARA) can be blocked via
the NC/PLC interface:
DB31, ... DBX9.3 (parameter set specification disabled by NC)
Note
If a parameter set changeover is requested by SCPARA while the parameter set changeover
is locked via the NC/PLC interface, the changeover is rejected without an error message.
Syntax
