Memory Configuring Machine Data, Sram - Siemens SINUMERIK 840D sl Programming Manual

Data description
9.1 Machine data for machine cycle runs
Notice
The following details in the machine data only refer to the use of SIEMENS measuring cycles
and are valid up to NCK software version 59.xx.yy
As of NCK software version 63.xx.yy, the standard machine data setting should be such that
the memory configuration requires no further adjustments when only SIEMENS measuring
cycles are installed for automatic mode and measuring in JOG.
If using applications requiring ShopMill, ShopTurn or another NC memory, the requirements
of these products must also be taken into account.
Notice
Machine data whose name starts "_MM" are memory configuring data. Changing these data
reallocates the memory. Data it contains will be lost.
If this memory is in the non-volatile memory range of the control (SRAM), the user data
(loaded programs and definitions, R-parameters, tool offsets, zero offsets, etc.) it contains
will be lost.
Therefore:
When first starting up the system, the following machine data should already be set at the
start of commissioning.
If user data is already present in SRAM, proceed as follows:
• Alarm 4400 (reorganization of the buffered memory) is displayed after changes to the
• In order to prevent the loss of data in this situation, the start-up archive MUST be read (in
• If this archive is then loaded into the NCU, the SRAM is configured and the archived data
