The torque and the temperature signal are already digitized in the rotor and
transmission is noise-free.
The torque signal can be zeroed
, scaled (2-point scaling) and
filtered via two low passes (LP1 and LP2). A further scaling of the frequency
output and the analog output is then possible.
Important
Scaling at position  (see Fig. 4.1) changes the internal calibration of the
torque transducer.
The rotational speed signal can be filtered and also scaled for analog output.
The angle of rotation signal, the power signal (low-pass filter LP) and the
temperature signal are only available on fieldbuses.
The torque signal and the rotational speed signal can be filtered via two low
passes connected in series, with filter outputs also being available separately.
The scaled, unfiltered torque signal is used to calculate power. The resultant,
highly-dynamically calculated power signal is filtered via a further low pass.
