22200 Channel %1 spindle %2 axis stopped during tapping
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: When tapping with compensating chuck (G63) the drilling axis was stopped via the NC/PLC interface
and the spindle continues to rotate. The thread and possibly also the tap were damaged as a result.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: 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 tapping 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.
Program Clear alarm with the RESET key. Restart part program
Continuation:
22250 Channel %1 spindle %2 axis stopped during thread cutting
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 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.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Check the axis-specific/spindle-specific
stop signals (DB 31 - 48, DBX 4.3).
Program Clear alarm with the RESET key. Restart part program
Continuation:
22260 Channel %1 spindle %2 thread might be damaged
Parameters: %1 = Channel number
%2 = Axis name
%3 = Block number
Definitions: 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!
Reaction: Alarm display.
Remedy: 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 executed in the
automatic DECODING SINGLE BLOCK mode.
Program Clear alarm with NC START or RESET key and continue the program.
