I'm encountering an issue where the polar logarithm in the AS configuration parameters doesn't correspond to the polar logarithm in the help documentation

The motor model 8LSA35.R0030D000-0 specified by B&R has 4 pole pairs. However, when I added this motor in AS, the configuration parameters show it as having 2 pole pairs. I have not modified any parameters. Is there an issue with the B&R specification, or is there a problem with the configuration?

I guess there is an issue in the configuration.
When I open one configuration of similar motor, the number of pole pair is correct:

Please report the issue to your local Support so they can create a CASE and R&D will fix that.

last note your motor is -0 and not -3, values are a little bit different, but not for pole pairs:

The polar logarithm is different.

This diagram is correct, but this motor has four poles, with a pole-pair count of two.
