Calibration File Elements
The following figure shows some elements of the calibration file:
Typical Calibration File
Items you may edit
• OutputPolarities—defines the polarities of the six outputs. Change these
only if your application requires different polarities from those on the
transducer label.
• ZeroAlgorithm—selects a zero algorithm for the application.
• AngleMode—selects the mode used for determining the encoder sine and
cosine.
• AngleFixed—used for non-spinning applications.
• AngleOffset— used for spinning applications. Normally you do not need to
change this value.
• EncoderSize 1 –defines the size of the encoder. The value will vary
depending on whether the application is using telemetry (0) or spinning slip
ring (1).

1. Some older versions of TI electronics may have firmware versions that are
not compatible with this parameter. If you are not using telemetry, this will
not affect the function of the SWIFT. To allow proper function, load a
current version of TIXFER or delete this line from the calibration file.
