U
Measuring log
Q281: Definition of whether the TNC is
to create a measuring log: 
0: No measuring log
1: Generate measuring log: with the standard setting 
the TNC saves the log file TCHPR421.TXT in the 
directory in which your measuring program is also 
stored.
2: Interrupt the program run and display the 
measuring log on the screen. Resume program run 
with NC Start.
U
PGM stop if tolerance error
Q309: Definition of
whether in the event of a violation of tolerance limits 
the TNC is to interrupt the program run and output an 
error message: 
0: Do not interrupt program run, no error message
1: Interrupt program run, output an error message
U
Tool number for monitoring
Q330: Definition of
whether the TNC is to monitor the tool (see “Tool 
monitoring” on page 388). Input range: 0 to 32767.9, 
alternatively tool name with max. 16 characters
0: Monitoring not active 
>0: Tool number in the tool table TOOL.T
U
No. of measuring points (4/3)
Q423: Specify
whether the TNC should measure the stud with 4 or 
3 probing points: 
4: Use 4 measuring points (standard setting) 
3: Use 3 measuring points
U
Type of traverse? Line=0/Arc=1
Q365: Definition of
the path function with which the tool is to move 
between the measuring points if "traverse to 
clearance height" (Q301=1) is active.
0: Move between operations on a straight line
1: Move between operations on the pitch circle
