Selecting the transition function
The direct selection of the following transition functions is realized
via the active "SafeMotion“profile by means of parameter "P‑0‑3264,
SMO: Safety function selection":
● "Safely-monitored deceleration with ramp-based trend monitoring"
(SMD
RampTrend
)
● "Safely-monitored deceleration with time-based trend monitoring"
(SMD
TimeTrend
)
● "Safely-monitored deceleration based on actual velocity" (SMD
ActVel
) .
Transition to the safe state
Transition function "Safely-monitored deceleration with ramp-based trend mon-
itoring"
When the transition function Safely-monitored deceleration with ramp-based
trend monitoring (SMD
RampTrend
) is selected, the NC-controlled or drive-con-
trolled transition of the axis is performed in accordance with the configuration
(P-0-3280.0.1).
In the case of NC-controlled transition, the higher-level control unit adjusts
the command value system for the drive in accordance with the monitoring
thresholds of the selected safety function.
