SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_STOP_VELO_TOL
Speed tolerance for safe acceleration monitoring
Min. input limit: 0.
Min. input limit: 0.
Protection level: 7/2
Actual speed tolerance for safe acceleration monitoring (SBR).
After the safe acceleration monitoring has been activated (by initiating a Stop B or C), then
this tolerance is applied to the actual speed.
It is not permissible that the actual velocity is greater than the limit that is therefore speci-
fied.
Otherwise, a Stop A will be initiated. This means that if the drive accelerates, this will be
identified very quickly.
/FBSIsl/ see Chapter 6.4: "Safe acceleration monitoring (SBR)"
(a recommended setting and setting formula are specified in this Chapter).
$MA_SAFE_SLIP_VELO_TOL
Speed tolerance, slip
Min. input limit: 0.
Min. input limit: 0.
Protection level: 7/2
Speed/velocity difference that, for a 2- -encoder system, is tolerated between the motor and
load sides without the crosswise data comparison between the drive and NCK signaling an
error.
MD36949 $MA_SAFE_SLIP_VELO_TOL is only evaluated, if MD36901
$MA_SAFE_FUNCTION_ENABLE, bit 3 is set.
