SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_STANDSTILL_VELO_LIMIT
Switchover speed SBH/SG
Min. input limit: 0.0
Min. input limit: 0.0
Protection level: 7/2
When the axis/spindle speed drops below this limit, it is considered to be at a "standstill".
A switch over to safe operating stop or to a lower velocity level is realized at the latest after
the time parameterized in MD37922 $MA_SAFE_STANDSTILL_DELAY expires. This
premature switchover is only realized if a velocity > 0.0 is parameterized in this MD.
MD37922 $MA_SAFE_STANDSTILL_DELAY and drive parameter p9567/p9569
$MA_SAFE_STANDSTILL_DELAY
Delay time, switchover to SBH/SG
Min. input limit: 0.0
Protection level: 7/2
If, when transitioning to a safe operating stop or to a lower velocity level, standstill is identi-
fied (see MD37920 $MA_SAFE_STANDSTILL_VELO_LIMIT), then at the latest, after this
transition time SBH or the selected SG stage becomes active. In this case, transition times
from Stop C, D and E as well as from SG to SBH or from a higher to a lower SG level are
interrupted or replaced by this delay time.
MD37920 $MA_SAFE_STANDSTILL_VELO_LIMIT and drive parameter p9567/p9569
$MA_SAFE_INFO_ENABLE
SIC/SCC and PROFIsafe enable
Min. input limit: 0
Protection level: 7/2
MD to enable evaluation of the SIC/SCC telegram between the control system and drive
and to enable the transfer of the PROFIsafe telegram between F- -PLC and drive.
Enables the evaluation of the Safety Contol Channel / Safety Info Channel (SCC/SIC).
Bit 0: For axes with NC safety functionality, only the drive- -integrated brake test is
supported via SIC/SCC.
Bit 1: Enables PROFIsafe communication between F- -PLC and drive
