SINUMERIK 802D sl, Diagnostics Manual, 06/2009

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

not possible to modify the value, as this would have cleared the contents of the user memory. This

was 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, for example, the LUD variables

are stored and the interpolation buffer size is entered). The capacity of this memory type is defined by

the current memory configuration and the value in MD18210 $MN_MM_USER_MEM_DYNAMIC.

- "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 configuration and the

value in MD18230 $MN_MM_USER_MEM_BUFFERED.

- "iS" stands for internal static or buffered user memory. This memory type is defined by the current

memory configuration (not settable). A few NCK functions use this memory.

Reaction: Alarm display.

Remedy: If the modification was unintentional, ignore the error message and continue. The alarm has no neg-

ative effects. The remedy depends on the access right and the current memory configuration of the

NCK:

- The intended change is not possible -> Try again with a smaller value. Observe the change in the

number of bytes.

- Is it possible to expand the memory? This option depends on the model in use. (Not possible if

parameter 4 equals "iS").

- The NCK user memory may have been set smaller than it could be. With the appropriate access

authorization, the machine data (see above) can be changed.

- If parameter 4 equals "iS" and no synchronous actions are used, then MD18232

$MN_MM_ACTFILESYS_LOG_FILE_MEM[2] = 0 can be set. Otherwise the desired machine data

change cannot be made.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

4090 Too many errors during power-up

Definitions: More than <n> errors occurred during control power-up.

Reaction: NC Start disable in this channel.

Alarm display.

Remedy: Set the machine data correctly.

Program Con-

tinuation:

Switch control OFF - ON.

4110 IPO cycle changed to %1 ms

Parameters: %1 = String (new IPO cycle time)

Definitions: The IPO cycle divisor was set to a value which was not an integral multiple of the position control cycle

divisor. The divisor (MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO) was increased.

For PROFIBUS/PROFINET: MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO has been modified

because of the modified DP cycle in the SDB (MD10050 $MN_SYSCLOCK_CYCLE_TIME).

Reaction: Alarm display.

Remedy: MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO has been modified.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

4111 PLC cycle increased to %1 ms

Parameters: %1 = String (new PLC cycle time)

Definitions: The PLC cycle divisor was set to a value which was not an integral multiple of the IPO cycle divisor.

The divisor (MD10074 $PLC_IPO_TIME_RATIO) has been increased.

For PROFIBUS/PROFINET: MD10074 $PLC_IPO_TIME_RATIO has been modified because of the

modified DP cycle in the SDB (MD10050 $SYSCLOCK_CYCLE_TIME).

Reaction: Alarm display.

Remedy: MD10074 $MN_PLC_IPO_TIME_RATIO has been modified.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program
