Quick start
Leaving the end position:
■
For travel-dependent cut-off, it will be imme-
diately changed to the set speed to keep the
runtimeasshortaspossible.Refertog.2,
curve a.
■
For torque-dependent cut-off, the end posi-
tion is left at the lowest possible speed for ap-
prox. 1 sec. prior to changing to the set speed;
refer to curve b.
The speed can however be lower than the end
position speed, refer to curve c.
Approaching the end position:
Shortly before reaching the end position range
(independent of the cut-off mode), the speed will
be reduced to the end position speed as for the
“Normal” setting.
Quick start/stop
Leaving the end position is identical to ’Quick
start‘ setting.
Approaching the end position:
■
For travel-dependent cut-off, the speed will
be reduced shortly before reaching the end
position so that the actuator is at standstill;
refertog.3,curvea.
■
For torque-dependent cut-off, the speed will
still be changed to the end position speed
before actually reaching the end position
range to avoid excessive torque and potential
damage to the valve, refer to curve b.
End position speed “Normal” is set in the factory.

8�6�17 Autom� TL adapt� end position
Due to longer operation, the travel between end positions OPEN and CLOSE (0 to100 %) for torque
dependent cut-off mode can change due to temperature, wear and deposits. If the actuator is in
torque dependent cut-off mode and should the change of the end position deviate by more than
±0.7 % from the currently set end position, the actuator will detect this deviation and reset the new
position as end position.
If the ‘Autom. TL adapt. end position‘ parameter is switched to ’Off‘, the autom. standardization
(adaption) is suspended and the end position set during commissioning remain unchanged. In case
of torque dependent tripping of the actuator during operation within the end position range, ‘End
position reached’ will be displayed. Should the actuator trip outside the end position range, the
actuator signals ‘Blocked in move“.
