Channel %1 block %2 zero velocity at block end point during thread cutting


%1 = Channel number

%2 = Block number, label


This alarm occurs only when several blocks with G33 follow in succession. The block end velocity in the specified block is zero although a further velocity block follows. The reasons for this can be, for instance:



Auxiliary function after motion

Auxiliary function output before the motion of the following block

Positioning axis in the block

-    Interpreter stop

-    NC Start disable in this channel.


-    Interface signals are set.

-    Alarm display.

Please inform the authorized personnel/service department. Modify the NC part program by removing any programmed "Stop at end of block" G09.

Modify general machine data 11110 AUXFU_GROUP_SPEC [n] for selecting the output time of an auxiliary function group by changing "Auxiliary function output before/after the movement" to "Auxiliary function output during the movement".

Bit 5 = 1: Auxiliary function output before movement

Bit 6 = 1: Auxiliary function output during movement

Bit 7 = 1: Auxiliary function output after movement
