Axis %1 difference safe input %2, NCK %3, drive %4
%1 = axis name, spindle 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 MD36950
$MA_SAFE_MODE_SWITCH_TIME.
Monitoring function involved (%2):
SS/SV Difference in SGE "deselect safe operating stop / safely
reduced speed"
SS Difference in SGE "deselect safe operating stop"
SV Difference in SGE "select safely reduced speed"
SP Difference in SGE "select safe limit positions"
SVOVR Difference in SGE "select SG correction"
Interface identifier NCK input (SPL interface):
<io> = parameterized system variable range (01=$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)
Interface identifier, drive input (%4):
DBX<byte><bit>=<value>
<byte> = byte number in the axis--specific DB (22, 23, 32, 33)
<bit> = bit number in the byte (0...7)
<value> = value of the drive SGE (0,1)
This alarm can be suppressed using the MD10096 $MN_SAFE_DIA-
