Activate machine data (NEWCONF)

The NEWCONF command activates all machine data. The function can also be activated in the
HMI user interface by pressing the "MD data effective" softkey.
When the "NEWCONF" function is executed there is an implicit preprocessing stop; in other
words, path movement is interrupted.
Syntax
NEWCONF
Meaning
NEWCONF:
Cross-channel execution of NEWCONF from the part program
If changes are made to axial machine data from the part program and then activated
with NEWCONF, NEWCONF will only activate the machine data containing changes affecting the
part program channel.
Note
In order to ensure that all changes are applied, the NEWCONF command must be executed in
every channel in which the axes or functions affected by the changes to the machine data is
being calculated.
No axial machine data is effective for NEWCONF.
An axial RESET must be performed for axes controlled by the PLC.
