SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

4075 Machine data %1 (and maybe others) not changed due to missing

permission level %2

Parameters: %1 = string: MD identifier

%2 = write-protection level of MD

Definitions: On executing a TOA file, an attempt has been made to write an item of data with a higher protection

level than the access authorization currently set in the control.

The item of data affected was not written.

This alarm is set only when access violation is detected for the first time.

Reaction: Alarm display.

Remedy: Set the required access level per password entry or delete the machine data concerned from the MD

file.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

4076 %1 Machine data could not be changed with permission level %2

Parameters: %1 = number of MD

%2 = access authorization set

Definitions: On executing a TOA file, an attempt has been made to write data with a higher protection level than

the access authorization currently set in the control.

The data affected was not written.

This alarm is issued when acknowledging Alarm 4075. It can be cleared only with Power On.

Reaction: NC Start disable in this channel.

Alarm display.

Remedy: Set the required access level by means of keyswitch or password entry or delete the machine data

concerned from the MD file program.

Program Con-

tinuation:

Switch control OFF - ON.

4077 New value %1 of MD %2 not set. Requested %3 bytes too much %4

memory.

Parameters: %1 = New value of machine data

%2 = Machine data number

%3 = Number of bytes to many requested

%4 = Type of memory

Definitions: An attempt was made to enter a new value in the specified memory configuration machine data.

The change is not made, since it would result in the user memory being deleted. 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 MD18210 MM_USER_MEM_DYNAMIC.

"S" stands for static or buffered user memory (typically the part programs but also compensation data,

R parameters and tool data). The capacity of this memory type is defined by the current memory

expansion and the value in MD 18230 MM_USER_MEM_BUFFERED.

Reaction: Alarm display.

Remedy: If the modification was unintentional, simply continue.

The alarm has no negative effects.

The remedy depends on the access authorization and the current memory expansion of the NC.

The intended change is mot possible -> try again with a lower value. Observe how the value of the

byte number changes.

Buy more memory? This option depends on the particular model used.

The NC user memory setting may be smaller than possible. The MDs (see above) can be altered using

the relevant access authorization.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.
