Install the latest version of the firmware
Redo offset detection (if the OBLAC Drives version is older than 21.3.0)
Perform Velocity Tuning or Position Tuning (depending on the application)
Attention
The analog calibration procedure must be repeated when the mechanical position of the magnetic ring
has changed or the Circulo was re-assembled. This can also occur when mechanical wear has impaired
the system performance.
An error will be triggered during startup in the Error Report Object 0x203F when the calibration is required

You can see a more detailed description of internal errors by using the CHECK ENCODER ERRORS button in
the Encoder Calibration tab.
1.2.2.3.2.3 Troubleshooting
If the Encoder Calibration Procedure has failed during recording, please check the error description and go
through the hints in this troubleshooting section. If the calibration is finished, but the resulting phase error
exceeds the permissible value, this is usually related to a mechanical issue or magnetic ring damage. It’s
possible to identify the cause based on the resulting Estimated phase error graph. There are typically 3
common outcomes:
1.2.2.3.2.3.1 The magnetic ring is too close to the encoder chip
Note the Nominal air gap for each encoder ring. If the ring is significantly closer, the following pattern will
appear in the calibration results: regular high frequency oscillations with a high amplitude.
