2.4.3 Behavior with faulty T programming
The behavior with faulty T programming depends on the configuration of the machine:
MD22562 TOOL_CHANGE_ERROR_MODE
Bit Value Meaning
7 0 Basic setting!
With the T programming, a check is made immediately as to whether the NC recogni‐
zes the T number. If not, an alarm is triggered.
1 The programmed T number will only be checked following D selection. If the NC does
not recognize the tool number, an alarm is issued during D selection.
This response is desirable if, for example, tool programming is also intended to achieve
positioning and the tool data is not necessarily available (circular magazine).
