SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MA_SAFE_VELO_STOP_REACTION[n]: 0 ... 3
Stop response, safely–reduced speed
Min. input limit: 0
Protection level: 7/2
The stop response programmed in this machine data is initiated if a limit value for
safely-reduced speed 1, 2, 3 or 4 is exceeded.
n = 0, 1, 2, 3 stands for SG1, SG2, SG3, SG4
The ones position defines the SG-specific selection of the stop response when the
safely-reduced speed is exceeded.
The tens position defines the behavior when the drive bus fails on an SG-specific basis if a
time greater than 0 was parameterized in $MN_SAFE_PULSE_DIS_TIME_BUSFAIL.
Value means:
0: Stop A
1: Stop B
2: Stop C
3: Stop D
4: Stop E
10:
Stop A, in addition, when the drive bus fails, the pulses are not immediately cancelled if this
SG stage is active.
11:
Stop B, in addition, when the drive bus fails, the pulses are not immediately cancelled if this
SG stage is active.
12:
Stop C, in addition, when the drive bus fails, the pulses are not immediately cancelled if this
SG stage is active.
13:
Stop D, in addition, when the drive bus fails, the pulses are not immediately cancelled if this
SG stage is active.
14:
Stop E, in addition, when the drive bus fails, the pulses are not immediately cancelled if this
SG stage is active.
This function is only active when MD 36961 has the value 5.
MD 10089: $MA_SAFE_PULSE_DIS_TIME_BUSFAIL
