8. After calibration the results are displayed in a status bar. If calibration was successful Track Error, Phase, Oset and
Gain elds will lit green. If they lit orange it means that calibration was successful but the parameters are at limit
values.
If parameters lit red calibration was not successful. In such case instructions for error solving are listed in “Error solver”
window on the right. Mechanically adjust the system by listed recommendations and repeat Calibration.
After successful calibration press “Write EEPROM”, to permanently store calibration settings into encoder.
Error solver:
Error Solution for Radial Ring Solution for Axial Ring
Gain Adjust ride height (air gap between
readhead and ring)
Adjust ride height (air gap between
readhead and ring)
Sin/Cos oset
Adjust the parallelism between the
magnetic ring and the sensing surface of
the readhead
Adjust the parallelism between the
magnetic ring and the sensing surface of
the readhead
Phase Adjust ride height (air gap between
readhead and ring)
Adjust radial and tangential position of
encoder
Track Error
Check magnetic carrier and read
head orientation, note the above
recommendation and adjust axial encoder
position
Check magnetic carrier and read
head orientation and note the above
recommendation
NOTE: Unsatisfactory calibration results can also be caused by poor or damaged magnetic ring.
