%1 Machine data could not be altered with permission level %2
%1 = Number of MDs
%2 = Preset access authorization
On executing a TOA file or when writing data from the part program an attempt has been
made to write data with a higher protection level than the access authorization currently
set in the control. The data in question have not been written and program execution is
continued without hindrance. This alarm is issued on acknowledging the alarm
EXBSAL_MD_PERMISSION_DENIED. It can be cleared only with Power On.
- Alarm display.
- NC Start disable in this channel.
Please inform the authorized personnel/service department. Set the required access level
by means of keyswitch or password entry or delete the machine data concerned from the
MD file/part program.
Switch control OFF - ON.
New value %1 of MD %2 not set. Requested %3 bytes too much %4 memory.
%1 = New value of machine data
%2 = Machine data number
%3 = Number of bytes requested that exceeded availability
%4 = Type of memory
An attempt was made to enter a new value in the specified memory configuration
machine data. It was not possible to modify the value, since this would clear the contents
of the user memory. This is because the memory requested exceeded the available
capacity.
The third parameter specifies the number of bytes by which the maximum user memory
was exceeded.
The fourth parameter specifies the type of memory whose limit was exceeded.
• "D" stands for dynamic or non-buffered user memory (this is where the LUD variables
are stored and the interpolation buffer size is entered, for example). The capacity of this
memory type is defined by the current memory expansion and the value in MD
MM_USER_MEM_DYNAMIC (18210).
• "S" stands for static or buffered user memory (this is where part programs, offset data,
R parameters, tool data, etc. are stored). This memory type is defined by the current
memory expansion and the value in MD MM_USER_MEM_BUFFERED (18230).
- Alarm display.
If the modification was unintentional, ignore the error message and continue. The alarm
has no negative effects. The remedy depends on the access rights and the current mem-
ory expansion of the NCK.
• The intended change is not possible -> try again with a smaller value. Observe the
change in the number of bytes.
• Buy more memory? This option depends on the model in use.
• The NCK user memory setting may be smaller than possible. The MDs can be changed
with appropriate access rights.
Clear alarm with the Delete key or NC START.
Incorrect configuration of indexing axis in MD %1
%1 = String: MD identifier
The assignment of a position table to an indexing axis or the contents of a position table
contains an error, or the length of a position table has been parameterized with 0.
