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 thread cutting 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: Modify the NC part program by removing any programmed "Stop at end of block" G09.
Modify general MD11110 $MN_AUXFU_GROUP_SPEC [n] for selecting the output time of an auxil-
iary 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 Con- Clear alarm with the Delete key or NC START.
tinuation:
10604 [Channel %1: ] Block %2 thread pitch increase too high
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The thread pitch 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 pitch increase or path length in the NC program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10605 [Channel %1: ] Block %2 thread pitch decrease too high
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The thread pitch decrease is causing an axis standstill in the thread block.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Reduce the thread pitch decrease or path length in the NC program.
