Access rights
The access rights defined in a GUD definition file remain valid and refer only to the GUD
variables defined in this GUD definition file.
Deletion behavior
If the content of a particular GUD definition file is reactivated, the old GUD data block in the
active file system is deleted first. The configured synchronized-action GUD is also reset at
this point. This process is also possible using the HMI in the operator area "Services" >
"Define and activated user data (GUD)".
10.3.4 Default axis identifier (NO_AXIS)
Function
AXIS type variables or parameters which have not been initialized by a value can be
provided with defined default axis identifiers. Undefined axis variables are initialized with this
default value.
Non-initialized valid axis names are recognized in synchronized actions by querying the
"NO_AXIS" variable. This non-initialized axis identifier is assigned the configured default axis
identifier by machine data.
Machine manufacturer
At least one valid existing axis identifier must be defined and pre-assigned using machine
data. All existing valid axis identifiers can however be pre-assigned. Please refer to the
machine manufacturer's instructions.
Note
During definition, newly created variables are now automatically given the value saved in the
machine data for default axis names.
For additional information on a definition applicable via machine data, see:
