4. Perform this step for non-spinning (fixed) applications. For spinning

applications, skip to Step 5.

A. Verify the value for AngleMode.

Set the AngleMode=1

In this mode, the sine and cosine RAM address is fixed. The encoder is
not used, nor is the encoder offset.

B. Edit the value for AngleFixed.

The AngleFixed value is used for non-spinning applications. This
value addresses the sine and cosine in memory when the angle mode is
set to 1 (fixed). Negative angles are converted to their positive
equivalent so that the readback value range is 0–360°.

You may set the fixed angle value when you are operating in fixed
angle mode (non-spinning applications) only if the transducer is rotated
from its correct Fz–Fx orientation on the road simulator. For
installations where the Fz-Fx orientation on the SWIFT cover(s) is
aligned with gravity. The correct setting is:

AngleFixed=0

If the SWIFT is installed at an angle to the desired Fz–Fx output axis,
set the AngleFixed value equal to the installed angle offset in degrees,
with clockwise rotation positive.

For example: AngleFixed = 45.

5. Save the changes and exit the editor.

6. Download the calibration file to the appropriate TI box. See
