Tripping torque/tripping force
The setting determines the torque or force to be achieved in relation to the load, to cause the motor
to trip. This applies to torque/force-dependent tripping in the end position as well as to a block. For
this reason, tripping torque or force also have to be set for travel-dependent cut-off mode.
Thetrippingtorque/trippingforceofanactuatorisbasedonthesizing,denedbytheapplication.
The tripping torque of the actuator is listed on the name plate.
A programmed addtional gear is considered during programming (refer to chapter „7.2 Additional
gear“ on page 36): The values for tripping torque/force are converted using the factor output/input
torque or input torque/output force and displayed. Only those values are provided for programming
in the display which are revelant to the combination of the actuator with the connected gearbox.
Setting values are displayed accordingly:
– Rotary gearbox: Tripping torque [Nm];
– Linear thrust unit: Tripping force [kN];
– Part-turn gearbox: Tripping torque [Nm].
The setting range for actuators of classes A and B ranges from 30 – 100 % and for modulating
actuators of classes C and D from 50 – 100 % in 10 % steps of the maximum torque each (for
some additional gears, other limit values apply) Default setting is the lowest possible value (typically
30 % of the maximum value for classes A and B, and 50 % of the maximum value for classes C and
D).
The following table shows the possible parameter values without additional gear.
■
For 2SG7 part-turn actuator, the tripping torque cannot be changed.
■
For 2SQ7, the tripping torque can be set via the torque switching, refer to supplement to opera-
tion instructions Y070.449.
■
If a cut-off mode or torque setting is selected that is not appropriate for the valve, the valve may
be damaged!

For reasons of simplicity, the designation “torque” shall also apply to force in the following de-
scription. For example, instead of torque or force dependent, only torque dependent will be used.
