Pos_abs is in NAN even after absolute reference configuration

Support ODrive S1 Support

Hi!

We have S1 and Pro. In Pro, we were able to get the absolute data via `pos_abs’ after setting the absolute reference frame configuration as mentioned in the documentation.

But in S1, same configuration doesn’t work, and the ‘pos_abs’ is still in ‘NaN’. We have tired this in several S1, it is still same.

We are looking for multi-turn absolute data in S1, any solutions to make `pos_abs’ to work or any other options.

Thanks!

Hi there!

Hm, interesting! There’s no fundamental difference in the firmware between the S1 and the Pro. Would you mind posting the exact configuration steps (effectively starting from a blank ODrive) you used for both the S1 and Pro?

Are the firmware versions the same? Latest is 0.6.9 / 0.6.9-1.
