Q303 in meas. cycle undefined!

Cause of error:
In one of the measuring cycles 410 to 418, you did not
define the parameter Q303 (measured value transfer)(current
value = -1). For reasons of security, however, selection of
the measured value transfer is required to write the results
of measurement in a table (datum table or preset table).
Corrective action:
Change parameter Q303 (measured value transfer) in the
measuring cycle that is causing the error:
- Q303=0: Write the measured values with respect to the
active workpiece coordinate system into the active datum
table (activate in the program with Cycle 7!).
- Q303=1: Write the measured values with respect to the
active machine-based coordinate system (REF values) into the
preset table (activate in the program with Cycle 247!).
- Q303=-1: Measured value transfer is undefined. This value
is automatically generated by the TNC when you download a
program that was written on a TNC 4xx or with an old
software level of the iTNC 530, or if during the cycle
definition you skipped the prompt for the measured value
transfer with the END key.

holes to be probed.
Corrective action:
Check the probing sequence. Refer to the User's Manual for
Touch Probe Cycles.

5700
Contradictory measuring points

Cause of error:
- In one of the probing cycles 400, 403 or 420, you defined
a contradictory combination of measuring points and
measuring axes.
- The selection of measuring points in Cycle 430 results in
division by 0.
Corrective action:
- For measuring axis = reference axis (Q272=1), the
parameters Q264 and Q266 are defined at different values.
- For measuring axis = minor axis (Q272=2), the parameters
Q263 and Q265 are defined at different values.
- For measuring axis = probe axis (Q272=3), the parameters
Q263 and Q265 or Q264 and Q266 are defined at different
values.
- Select the measuring points so that they always have
different coordinates in all axes.

5709
Circle data error

Cause of error:

Cause of error:
The given tool vectors of two successive points permit no
interpolation.
Corrective action:
Define the interpolation points at a closer distance.

7969
Application %s cannot be started

Cause of error:
Due to insufficient system resources (e.g. memory-consuming
high-speed cutting) a part of the system software cannot be
loaded.
Corrective action:
Call the desired function again later.

7971
Process cannot be run

Cause of error:
One of the processes required for editing files (e.g.
background copying) could not be started. There may be too
many of these processes already active.
Corrective action:
- Wait until background copying processes are completed.
- Restart your control.

be identical to the old file name.
Corrective action:
Enter the new file name so that it differs from the old file
name.

7974
File type cannot be changed

Cause of error:
You tried to convert a binary-type file into another
binary-type file.

setting up the directory tree).
Corrective action:
- Allow sufficient time for the file operation to be
executed before you cancel it with the "END" key.
- Run the file operation in the background.
- Timeout on network drive: Check whether the server is
switched on and whether it reacts to access attempts.

Line/block too long

Cause of error:
The TNC found a data block or a line with a length of more
than 512 characters in the selected file.
The TNC is unable to read or process such files.
Corrective action:
- Copy the ASCII files to a network drive and shorten the
lines using an editor that has no line length limit.
- Binary-coded TNC files must be copied from an external
device to the TNC after the file contents have been checked
and corrected if required.

7981
File does not exist

Cause of error:
- The given file does not exist
- The given file has been deleted since last used
- smarT.NC: You selected an .HU program that uses a point
table that does not exist on the TNC hard disk
Corrective action:
- Use an existing file for the selected file operation
- Check the .HU program for missing point tables and restore
or read-in the missing files

8001

file(*.SEC.DEP).
- Reduce the path name to a permissible total length.
- Switch the window again later, e.g. after you have
selected another program.

8072
Read-only section file!

Cause of error:
You write-protected the section file (*.SEC.DEP) although
this is not permitted.

Remove the write-protection from the section file
(*.SEC.DEP), since otherwise the TNC will be unable to
update the section file. This also applies if the program
sections are currently not being displayed on the screen.

8090
Reciprocating not possible!

Cause of error:
In a pocket cycle (rectangular pocket, circular pocket, SL

SPAWN/SUBMIT is blocking a context switch

Cause of error:
The PLC in-code tracer cannot be started because one of the
SPAWN/SUBMIT jobs in the system blocked all context
switching for more than 3 seconds.
Corrective action:
Every program loop in a SPAWN/SUBMIT job must contain an
opportunity to switch contexts (cooperative multitasking).
You can do this by calling one of the PLC modules 9260,
9262, 9263, 9212, 9216, 9217, 9108 or 9109.
You can find the faulty SPAWN/SUBMIT job on the process
monitor because it stays the "RUN+" state for a long time.
