H2: Auxiliary function outputs to PLC 88.1 Brief description8.1.1 FunctionAuxiliary functions permit activation of the system functions of the NCK and PLC user functions.Auxiliary functions can be programmed in:● Part programs● Synchronized actions● User cyclesFor detailed information on the use of auxiliary function outputs in synchronized actions, see:References:Function Manual, Synchronized ActionsPredefined auxiliary functionsPredefined auxiliary functions activate system functions. The auxiliary function is also outputto the NC/PLC interface.The following auxiliary functions are predefined:Type Function Example MeaningM Additional function M30 End of programS Spindle function S100 Spindle speed 100 (e.g. rpm)T Tool number T3 Tool number 3D, DL Tool offset D1 Tool cutting edge number 1F Feedrate F1000 Feedrate 1000 (e.g. mm/min)Userdefined auxiliary functionsUser-defined auxiliary functions are either extended predefined auxiliary functions or user-specific auxiliary functions.Extension of predefined auxiliary functionsExtension of predefined auxiliary functions refers to the "address extensions" parameter. Theaddress 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.
