In case of a ring damage, the phase error curve would have a unique error peak.
1.2.3.3.2.4 Encoder system diagnostic
This set of features allows to:
Check the distance between the chip and the magnetic ring
Detect axial runout of the encoder ring
Read error states directly from the encoder chip
1.2.3.3.2.4.1 Magnetic ring distance checker
This feature can assist during the prototyping phase of the design. It computes the air gap based on the ring’s
magnetic field strength and recommends next action.
Note
Earlier batches of the encoder rings had a weaker field and thus the computed distances might be
overestimated. Please use this feature carefully with older encoder rings. It shouldn’t be a primary
information source during the ring mounting process, mechanical design should take a priority.
Note
The releases of the OBLAC Drives at version v21.1.0-beta.4 and before display the estimated air gap
based on nominal air gap of 0.5 mm. Please update the OBLAC Drives.
