SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
The alarm is no longer displayed when the alarm cause has been re-
moved. No other operator actions are required.
The alarm automatically disappears after the delay time has expired
that is defined in MD $MA_SAFE_PULSE_DIS_CHECK_TIME – and
the withdrawal of the SGE "test stop selection" if the control detects
that the drive pulses have been cancelled – i.e. the test has been suc-
cessfully completed. An unsuccessful test can be recognized as a re-
sult of Alarm 27001 with fault code 1005 or Alarm 27024.
Checksum error occurred %1 %2
%1 = reference to the code section or table
%2 = table number
Checksum error in safety–related code or safety–related data.
The safety monitoring functions (Safety Integrated) in the NCK could
be corrupted.

Please take extreme caution when continuing with any work. Re–load
code and data as soon as possible (power on). If this fault occurs
again, contact the service department.
Power–down the control system and power–up again.
Axis %1 difference safe input %2, NCK %3, drive %4
%1 = axis number
%2 = monitoring function involved
%3 = interface identifier, NCK input
%4 = interface identifier, drive input
A difference has been detected at the specified safe input. The state of
the specified input signal differs in the two monitoring channels NCK
and drive during the time set in $MA_SAFE_MODE_SWITCH_TIME.
Monitoring function involved (%2):
SS/SV Difference in SGE "deselect safe operating stop/
safely reduced speed"
SS Difference in SGE "deselect safe operating stop"
SV Difference in SGE "select safely reduced speed"
SP Difference in SGE "select safe limit positions"
SVOVR Difference in SGEs "select SG correction"
For the case that SGE is parameterized at the SPL interface
<io> = parameterized system variable range (01=$A_INSID,
02=$A_INSED)
<dword> = system variable – double word (1,2)
<bit> = bit number in the system variable – double word (1...32)
<value> = value of the NCK–SGE (0,1)
