SINUMERIK 840D/810D Start-Up Guide (IADC) – 03/2006 Edition
If the NCU is used with a larger memory, this memory must be enabled.
S Enter the value 1900 in MD 18230: MM_USER_MEM_BUFFERED.
S Stream off a standard system start-up file.
S POWER ON (to reorganize the memory).
S Download the standard system start-up file to the control once more.
MD 18060 shows how much RAM is still free.
Recommendation:
Values > 15000 should be displayed so that data (e.g. tool offsets) can be read
in at any time.
Note
For normal applications, leave all other memory settings unchanged.
Changing the following machine data causes the control SRAM to be
reconfigured. In the event of a change, the “4400 MD change caused
reorganisation of the buffered memory (data lost!)” alarm is output. When this
alarm is output, all data must be saved because all buffered user data will be
erased during the next booting.
