H2: Auxiliary function outputs to PLC

8.1

Brief description

8.1.1

Function

Auxiliary functions permit activation of the system functions of the NCK and PLC user functions. Auxiliary
functions can be programmed in:
• Parts programs
• Synchronized actions
• User cycles
References:
For detailed information on using auxiliary function outputs in synchronized actions, refer to the Function Manual,
Synchronized Actions.
Predefined auxiliary functions
Predefined auxiliary functions activate system functions. The auxiliary function is also output to the NC/PLC
interface.
The following auxiliary functions are predefined:
Type Function
M Special function
S Spindle function
T Tool number
D, DL Tool offset
F Feed
User­defined auxiliary functions
User-defined auxiliary functions are either extended predefined auxiliary functions or user-specific auxiliary
functions.
Extension of predefined auxiliary functions
Extension of predefined auxiliary functions refers to the "address extensions" parameter. The address extension
defines the number of the spindle to which the auxiliary function applies. The spindle function M3 (spindle right) is
predefined for the master spindle of a channel. If a 2nd spindle is assigned to a channel, a corresponding user-
defined auxiliary function must be defined that extends the predefined auxiliary function.
