Sinumerik Alarm 14770 Channel %1 block %2 auxiliary function programmed incorrectly
%1 = Channel number
%2 = Block number, label
The permissible number of programmed auxiliary functions per NC block has been exceeded or more than one auxiliary function of the same auxiliary function group has been programmed (M and S function). In the user-defined auxiliary functions, the maximum number of auxiliary functions per group in the NCK system settings has been defined for all auxiliary functions by means of the machine data 11100 AUXFU_MAXNUM_GROUP_ASSIGN (default: 1) For each user-defined auxiliary function to be assigned to a group, the assignment is effected through 4 channel-specific machine data. Return jump from asynchronous subprogram with M02/M17/M30, whereby the M code is not alone in the block. This is impermissible if the asynchronous subprogram interrupts a block with WAITE, WAITM or WAITMC.
Remedy: Program M02/M17/M30 alone in the block or replace via RET.
22010 AUXFU_ASSIGN_TYPE: type of auxiliary function, e.g. M
22000 AUXFU_ASSIGN_GROUP: required group
22020 AUXFU_ASSIGN_EXTENSION: any required extension
22030 AUXFU_ASSIGN_VALUE: function value
– Correction block is reorganized.
– Interface signals are set.
– Alarm display.
Correct the part program – max. 16 auxiliary functions, max. 5 M functions per NC block,max. 1 auxiliary function per group.
Clear alarm with NC START or RESET key and continue the program.
