8.3 Userdefined auxiliary functions
There are two uses for user-defined auxiliary functions:
• Extension of predefined auxiliary functions
• User-specific auxiliary functions
Extension of predefined auxiliary functions
Because there is only one set of machine data for the predefined auxiliary functions, they can only ever be used
to address one spindle of the channel. To address further spindles, user-defined auxiliary functions must be
parameterized to supplement the predefined auxiliary functions.
Extension of predefined auxiliary functions refers to the "address extensions" parameter. The number of the
spindle that the auxiliary function refers to is entered in the "address extension" parameter.
The relevant predefined auxiliary functions can be extended for the following system functions:
Example:
Extension of the predefined auxiliary function for the system function "spindle right" for the second and third
spindle of the channel.
