Hi,
In the "Power Unit with Fixed-Displacement Pump Demo", the port R of the torque sensor is attached to the angular velocity source and port C to the shaft whose torque is being monitored. My question is that Port C is the reference probe, so why it is connected to the shaft? shouldn't it be connected to the angular velocity port?
(Type sh_power_unit_fxd_dspl_pump in the command window.This will open the model and the orientaiton can be checked)

Any comment will be highly appreciated. Thanks!
