SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
10.2 NCK safety alarms for Sinumerik 840D sl
Axis %1 checksum error %2 safety-relevant monitoring functions.
Acknowledgement and acceptance test required!
%1 = axis number
%2 = index of $MA_SAFE_ACT_CHECKSUM
The relevant MDs $MN_SAFE_..., $MN_PROFISAFE_..., $MA_SAFE
... are protected by a checksum. The alarm indicates that the current
checksum is no longer the same as the reference checksum that has
been saved, i.e. this means that an MD value has either been changed
illegally or data is corrupted. The 2nd index specifies in which field
entry of $MA_SAFE_ACT_CHECKSUM the error was detected.

Check MDs. Have the checksum re-calculated. Safety functions should
be subject to a new acceptance test.
Power-down the control and power-up again
Axis %1 parameterization of the MD %2[%3] not valid
%1 = axis number
%2 = machine data identifier
%3 = machine data index
The parameterization of machine data %2 is incorrect. An additional
indication is the field index of the machine data. If the machine data is a
single machine data, a zero is specified as array index. This alarm
occurs in the following contexts:
– The conversion of the specified MD into the internal computation
format resulted in an overflow.
– Error when parameterizing the input/output assignments for the
SGEs/SGAs.
– One of the activated cam positions is outside the actual value
modulo range.
– The function "actual value synchronization 2-encoder system" (slip)
is selected for a single-encoder system or a function with absolute
reference (SE/SN) is simultaneously selected .
– $MA_SAFE_FUNCTION_ENABLE
A safety function was enabled without the safety function SBH/SG
having been enabled.
An axial SGE/SGA was parameterized at the SPL interface
(segment number = 4) and the function enable for the external stops
(bit 6) is missing.
The cam synchronization was activated via bit 7 without the cams
having been enabled via bit 8 ... bit 15 or via
$MA_SAFE_CAM_ENABLE.
