The free SRAM memory is displayed in machine data
S
MD18060: INFO_FREE_MEM_DYNAMIC (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.
Modifying the machine data listed in Table 10-14 results in a reconfiguration of
the SRAM with a loss of all user data. Before the change comes into effect in
the NC, the following alarm message is output:
S
Alarm: "4400 MD change results in reorganization of the non–volatile
memory (loss of data!)"
Notice
When reconfiguring the SRAM memory, all user data are lost. To prevent data
loss, a series machine start-up file should be created prior to reconfiguration
(see Section 14.2, Page 14-451).
