Edit the Calibration File
Setting up the Transducer Interface
2. If necessary, edit the value for Polarity (see the table below).
The polarities that match the coordinate icon on the transducer are:
Fx=0
Fy=0
Fz=0
Mx=1
My=0
Mz=1
3. Perform this step for spinning application. For non-spinning applications,
skip to Step 4.
A. Verify the value for AngleMode.
Set the AngleMode=0
In this mode, the encoder pulses are summed in with the offset. At the
end of the process the value in the TI internal memory and is used to
perform the rotational transformation of the output signals.
