11.2 NCK safety alarms for SINUMERIK 840D sl
27033 Axis %1 parameterization of the MD %2[%3] invalid, error code %4
Parameter %1 = axis name, spindle number
%2 = MD name
%3 = MD field index for MD name
%4 = error code, note regarding the cause
Explanation The parameterization of the machine data is incorrect. An additional indication is the field index of the machine
data. If the machine data is a single item of machine data, a zero is specified as a field index. This alarm
occurs in the following contexts:
● 1: The conversion of the specified MD into the internal computation format resulted in an overflow.
● 2: Error when parameterizing the input/output assignments for SGE/SGA.
● 3: One of the activated cam positions is outside the actual value modulo range.
● 4: The function "actual value synchronization 2-encoder system" (slip) is selected for a single-encoder
system.
● 5: The function "actual value synchronization 2-encoder system" (slip) is simultaneously selected with a
function with absolute reference (SE/SN).
● 6: A safety function was enabled in MD36901 $MA_SAFE_FUNCTION_ENABLE without the safety
functions SBH/SG having been enabled.
● 7: An axis-specific SGE/SGA was parameterized at the SPL interface (segment number = 4) and the
function enable for the external stops is missing (MD36901 $MA_SAFE_FUNCTION_ENABLE, bit 6).
● 8: In MD36901 $MA_SAFE_FUNCTION_ENABLE using bit 7 cam synchronization is activated, without
the cams having been enabled using bits 8...15.
● 12: A zero was entered in MD36917 $MA_SAFE_ENC_GRID_POINT_DIST.
