SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_VELO_STOP_MODE
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.
= 0, 1, 2, 3 correspond to STOP A, B, C, D – common for each SG level
= 5 means that the stop response can be configured for specific SGs in MD 36963.
The ones position defines the selection of the stop response when the safely reduced
speed is exceeded.
The tens position defines the behavior when the drive bus fails if a time greater than 0 was
parameterized in $MN_SAFE_PULSE_DIS_TIME_BUSFAIL.
0: Stop A
1: Stop B
2: Stop C
3: Stop D
4: Stop E
5:
SAFE_VELO_STOP_MODE not valid – the stop response is parameterized using MD
SAFE_VELO_STOP_REACTION
10:
Stop A, in addition when the drive bus fails and SG is active, the pulses are not immediately
cancelled
11:
Stop B, in addition when the drive bus fails and SG is active, the pulses are not immediately
cancelled
12:
Stop C, in addition when the drive bus fails and SG is active, the pulses are not immedi-
ately cancelled
13:
Stop D, in addition when the drive bus fails and SG is active, the pulses are not immedi-
ately cancelled
14:
Stop E, in addition when the drive bus fails and SG is active, the pulses are not immediately
cancelled
For a value of 5 in this MD, the stop response for each SG stage is selectively defined
$MA_SAFE_VELO_ST OP_REACTION.
MD 36931: $MA_SAFE_VELO_LIMIT[n]
MD 36963: $MA_SAFE_VELO_STOP_REACTION[n]
$MA_SAFE_POS_STOP_MODE
Stop response, safe limit position
Min. input limit: 2
Protection level: 7/2
When passing a safe limit position 1 or 2, then the stop response specified in this machine
data is initiated.
2: STOP C
3 STOP D
4 STOP E
