SRAM memory
Free memory
The free SRAM memory is displayed via the following machine data:
●
MD18060 $MN_INFO_FREE_MEM_STATIC (free static memory)
The free SRAM should not be less than 15,000 bytes to ensure that data (e.g. tool offsets)
can be read in at all times.
Reconfiguation of the SRAM memory
Modifying the machine data listed in the following table results in a reconfiguration of the
SRAM with a loss of all user data. Before the change becomes effective in the NC, the
following alarm message is generated:
●
Alarm "4400 MD change results in reorganization of the buffered memory (loss of data!)"
NOTICE
When reconfiguring the SRAM memory, all user data are lost. To avoid data losses, a
series startup file should be created before reconfiguration (see Section "Creating a
