SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
The axis--specific MD $MA_SAFE... and MD10393
$MN_SAFE_DRIVE_LOGIC_ADDRESS are protected by a checksum.
The alarm indicates that the actual checksum no longer matches the
saved checksum, i.e. that either a piece of data was illegally changed
or is corrupt.
In the commissioning phase (SPL commissioning mode active), instead
of the individual axis--specific checksum alarms (27032, 27035 and
27060), the axis--specific group alarm 27132 is displayed. MD10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL can be used to further
reduce the alarm display so that only one alarm is displayed for all axes
(global group alarm 27135).
