Overview of Alarms
NCK alarms
10601 Channel %1 block %2 zero velocity at block end point during thread
cutting
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: 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:
- G9
- Auxiliary function after motion
- Auxiliary function output before the motion of the following block
- Positioning axis in the block
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: 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
Program Clear alarm with the RESET key. Restart part program
Continuation:
10602 Channel %1 block %2 velocity limitation during thread cutting
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In the displayed thread block, the axis would exceed its maximum velocity when the spindle override
is in the maximum position.
Reaction: Local alarm reaction.
Alarm display.
Remedy: If the axis velocity is not limited (faultless thread) no remedial measures are necessary. Otherwise, a
lower spindle speed must be programmed for the thread block.
Program Clear alarm with the Delete key or NC START.
Continuation:
10604 Channel %1 block %2 thread lead increase too high
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The thread lead increase is causing an axis overload. A spindle override of 100% is assumed during
verification.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Reduce the spindle speed, thread lead increase or path length in the NC program.
Program Clear alarm with NC START or RESET key and continue the program.
