10.2 NCK safety alarms for Sinumerik 840D sl
This is the case if the safe actual positions of the NCK and drive do not
differ but instead there is an entry in drive parameters r9710/r9711 (and
the 1 appears in parameter r9725) –> i.e. the fault code corresponds to
the fault profile of fault code 1. This can also be identified using the
fault message if for %3 = supplementary info comparison value NCK or
%4 = supplementary info comparison value drive no real limit value is
output but only the value of the calculated tolerance (refer to the
example above (SG1 = 2000 mm/min = 0.4 mm/monitoring clock
cycle), a value of 400 would be displayed as 4%).
Remedy: Refer to fault code 1.
– 44
Upper limit value for SG1 = position actual value + MD 36931
$MA_SAFE_VELO_LIMIT[0] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 45
Lower limit value for SG1 = position actual value – MD 36931
$MA_SAFE_VELO_LIMIT[0] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 46
Upper limit value for SG2 = position actual value + MD 36931
$MA_SAFE_VELO_LIMIT[1] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 47
Lower limit value for SG2 = position actual value – MD 36931
$MA_SAFE_VELO_LIMIT[1] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 48
Upper limit value for SG3 = position actual value + MD 36931
$MA_SAFE_VELO_LIMIT[2] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 49
Lower limit value for SG3 = position actual value – MD 36931
$MA_SAFE_VELO_LIMIT[2] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 50
Upper limit value for SG4 = position actual value + MD 36931
$MA_SAFE_VELO_LIMIT[3] referred to a monitoring clock cycle
Remedy
Refer to Section 44–57 (hidden fault code 3 or 1)
– 51
Lower limit value for SG4 = position actual value – MD 36931
$MA_SAFE_VELO_LIMIT[3] referred to a monitoring clock cycle
