This machine data defines the limit speed n
If this velocity limit is fallen below, SGA "n < n
Refer to Section 6.6: "SGA "n < n
$MA_SAFE_STOP_VELO_TOL
Velocity tolerance for the safe braking ramp.
Min. input limit: 0.0
Protection level: 7/2
Tolerance actual velocity for Safe Braking Ramp (SBR).
After the safe braking ramp has been activated (by initiating a Stop B or C), then this
tolerance is applied to the actual velocity.
It is not permissible that the actual velocity is greater than the limit that is therefore
specified.
Otherwise, a Stop A is initiated; this means that if the drive accelerates, then this is
detected as quickly as possible.
Refer to Section 6.4: "Safe braking ramp (SBR)"
(a recommended setting and setting formula are specified in this Chapter).
