SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MN_SAFE_DIAGNOSIS_MASK
Safety Integrated diagnostic functions
Min. input limit: 0
Protection level: 7/2
Bit 0=0
SGE differences between NCK and the drive monitoring channels are not displayed
Bit 0=1
Default: SGE differences between NCK and the drive monitoring channels are displayed
Differences between the following SGEs are detected (the listed bit numbers refer to the
axial mapping of the SGEs – these correspond to the following VDI interface assignment):
Bit 0: SBH/SG de-selection
Bit 1: SBH de-selection
Bit 3: SG selection, bit 0
Bit 4: SG selection, bit 1
Bit 12: SE selection
Bit 28: SG correction, bit 0
Bit 29: SG correction, bit 1
Bit 30: SG correction, bit 2
Bit 31: SG correction, bit 3
The differences are indicated using message Alarm 27004.
Bit 1 = 0:
Default: Displays an unsuccessful SPL start after the timer defined in MD
SAFE_SPL_START_TIMEOUT has expired with Alarm 27097
Bit 1 = 1:
Display of Alarm 27097 is suppressed.
Alarm 27097 indicates, that in spite of the SPL configuration, SPL was not started after the
time set in MD SAFE_SPL_START_TIMEOUT expired. For the cause, refer to the
description of Alarm 27097.
$MN_SAFE_SPL_STOP_MODE
Stop response for SPL errors
Min. input limit: 3
Protection level: 2/7
Selects the stop response when errors are detected in the crosswise data comparison of
NCK and PLC-SPL
3: Stop D
4 Stop E
When the value 4 is entered in this MD (Stop E) without enabling the external Stop E in all
axes with SI function enable signals ($MA_SAFE_FUNCTION_ENABLE not equal to 0)
results in Alarm 27033, "Axis %1 Invalid parameterization of MD
MN_SAFE_SPL_STOP_MODE".
To remedy this, either parameterize Stop D or set bit 4 and bit 6 in
$MA_SAFE_FUNCTION_ENABLE for all of the axes involved. If this MD is set to 4, then
DBX36.1 in DB18 must also be set to signal the PLC about this parameterization. For a
different parameter assignment, Alarm 27090 is output, "Error for crosswise data
comparison NCK-PLC".
