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? ![2](https://europe1.discourse-cdn.com/brcommunity/original/2X/1/1d0af0ff18d992086e8baef6b2e82d1cf0c655ed.png) ![1](https://europe1.discourse-cdn.com/brcommunity/original/2X/5/54b6006e509850c0fb59a941c2920ae8a4689867.png) ---

> [@boyu.zhu](#): > > 8LSA35.R0030D000-0 I guess there is an issue in the configuration. When I open one configuration of similar motor, the number of pole pair is correct: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/0/01181a3f3d8170457374653fbabe69354f44f4c8.png) Please report the issue to your local Support so they can create a CASE and R&D will fix that.

The polar logarithm is different. ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/8/8dcd190c84a879d37aaa658cb2db650d54628901.png) ---

> [@valerio.manenti](#): > > last note your motor is -0 and not -3, values are a little bit different, but not for pole pairs: This diagram is correct, but this motor has four poles, with a pole-pair count of two.
