SAM/SBR (extended functions)

Parameterize the alternative brake monitoring functions "Safe Acceleration Monitor" ("SAM")
and "Safe Brake Ramp" ("SBR") in the following dialogs:
Safe Acceleration Monitor (SAM)
The "Safe Acceleration Monitor" (SAM) function is used to safety monitor braking along the
OFF3 ramp. The function is active for "SS1", "SS2" or STOP B and STOP C.
As long as the speed reduces, the converter continuously adds the adjustable speed
tolerance p9548 to the current speed so that the monitoring tracks the speed. If the speed is
temporarily higher, the monitoring remains at the last value. The converter reduces the
monitoring threshold until the "Shutdown speed" has been reached.
