This information is part of the Modelica Standard Library maintained by the Modelica Association.
The cut-torque acting between the two frames to which this model is connected, is determined and provided at the output signal connector torque (= frame_a.t). If parameter positiveSign = false, the negative cut-torque is provided (= frame_b.t).
Via parameter resolveInFrame it is defined, in which frame the torque vector is resolved:
|world||Resolve vector in world frame|
|frame_a||Resolve vector in frame_a|
|frame_resolve||Resolve vector in frame_resolve|
If resolveInFrame = Types.ResolveInFrameAB.frame_resolve, the conditional connector "frame_resolve" is enabled and output torque is resolved in the frame, to which frame_resolve is connected. Note, if this connector is enabled, it must be connected.
In the following figure the animation of a CutTorque sensor is shown. The dark blue coordinate system is frame_b, and the green arrow is the cut torque acting at frame_b and with negative sign at frame_a.
Description: Frame in which output vector(s) is/are resolved (world, frame_a, or frame_resolve)
Description: = true, if animation shall be enabled (show arrow)
Description: = true, if torque with positive sign is returned (= frame_a.t), otherwise with negative sign (= frame_b.t)
Default Value: 1000
Type: Real (N·m/m)
Description: Torque arrow scaling (length = torque/Nm_to_m)

Type: Diameter (m)
Description: Diameter of torque arrow
Default Value: Modelica.Mechanics.MultiBody.Types.Defaults.TorqueColor
Description: Color of torque arrow

Description: Coordinate system a
Description: Coordinate system b
Description: Output vectors are optionally resolved in this frame (cut-force/-torque are set to zero)
Description: Cut torque resolved in frame defined by resolveInFrame
