Erasure of SRAM
The following machine data cause a reconfiguration of the control SRAM when
their contents are changed. When a change is made, the alarm "4400 MD
through MD
alteration will cause reorganization of buffer (data loss!)" is displayed. When this
change
alarm is output, all data must be saved because all buffered user data will be
erased during the next booting.
