8�6�15 Runtime monitoring
As standard, SEVEN actuators are equipped with runtime monitoring. When running the actuator
forthersttimeoveradistanceofatleast3%oftheentiretravelaftersettingtheendpositions,
the runtime is measured and stored in a non-volatile memory. The actual motor frequency or speed
is taken into account during the measurements.
During future operation, it will be checked whether the position reached after the runtime is plausi-
ble. Tolerances due to different loads and measurement inaccuracies during position measurement
are taken into account. If the expected position is not reached in time, the actuator changes over to
the “fault” state and signals “runtime error”.
This internal monitoring can be deactivated, i.e. exceeding the runtime will not cause a fault signal.
This can prove useful for special applications.

8�6�16 End position speed
Withintheendpositionranges,theactuatoroperatesatanendpositionspeeddenedforeach
devicetochangetothedenedspeedwhenleavingtheendpositions.
For extremely long total runtimes, it may be desired that the actuator changes as quickly as pos-
sible, even before leaving the end position range to the adjusted, typically high speed. It may,
however,alsoberequiredthattheactuatoroperatesaslongaspossibleatthedenedspeedwhen
approaching the end position to be able to quickly stop in the end position.
