Please inform the authorized personnel/service department. Provide an interlock in the
PLC user program so that no axis stop can be initiated when tapping is active. If the tap-
ping operation is to be terminated under critical machine conditions, the spindle and the
axis should be stopped simultaneously if at all possible. Slight differences are then
accommodated by the compensating chuck.
Clear alarm with the RESET key. Restart part program
Channel %1 spindle %2 axis stopped during thread cutting
%1 = Channel number
%2 = Axis name, spindle number
The thread cutting axis has been stopped while a thread block was active.
The stop can be caused by VDI signals that cause the feed to be interrupted.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Please inform the authorized personnel/service department. Check the axis-specific/spin-
dle-specific stop signals (DB 31 - 48, DBX 4.3).
Clear alarm with the RESET key. Restart part program
Channel %1 spindle %2 thread might be damaged
%1 = Channel number
%2 = Axis name
%3 = Block number
When DECODING SINGLE BLOCK has been selected and there is a chain of thread
blocks, then machining pauses occur at the block limits until the next block is executed
with the new NC Start.
In normal single block mode, the program is stopped by a higher-level logic only at the
block boundaries at which no contour distortions or contour errors can occur. With
chained thread blocks, this is the last thread block!
- Alarm display.
If only one thread block has been programmed, the alarm message can be ignored.
If there are several consecutive thread blocks, this machining section must not be exe-
cuted in the automatic DECODING SINGLE BLOCK mode.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 maximum velocity of thread axis at position %3 reached
%1 = Channel number
%2 = Block number, label
%3 = Position
The axis velocity is too high for thread cutting. The maximum feedrate was reached at the
axis position indicated. The velocity of the thread axis depends on:
• The programmed thread pitch
• The programmed thread lead change (G34)
• The thread length (G34)
• The defined spindle speed (part program, FC18, synchronized action)
• The spindle override (path and individual axis overrides are ineffective)
- Alarm display.
Reduce the velocity for at least one of the above factors.
Clear alarm with the Delete key or NC START.
