Please help me set the synchronous motor parameters using the following nametag.

Hello,

Check **[Guide: Motion Comissioning for Beginners](https://community.br-automation.com/t/guide-motion-comissioning-for-beginners/1679)** and **[Running different brand servo motor with ACOPOS 1016](https://community.br-automation.com/t/running-different-brand-servo-motor-with-acopos-1016/4793).** It should help you.

Hello @thachnt ,

Please post specific questions. Both of your posts show the same screenshot and no specific question at all (since the data seems to be filled in already). The latter one also ignores Pavel’s reply or at least you didn’t say why this answer wasn’t able to help you.

Best regards

Hi @thachnt ,  
if you need help for sure we need more information.  
In your hw configuration I see only CPU + drive + motor (and I suspect with no load) is very possible you have found some of our hw somewhere and you are doing some tests because you want to learn or system…that’s good.  
If I’m you I’ll check:

1. you need more information than the one reported on nameplate. In general, the parameters for the motor should come from the motor manufacturer. These are physical/electrical characteristics of their device, of which they are the experts. Again if I’m you, as a reference, I will try the auto motor identification available in our drive (steps described in the link below).
2. encoder: which encoder do you have, Have did you configure the encoder interface? You see this information in the network command trace
3. Are you sure all pars in the ACOPOS pars tables are active on the drive? Check the final values of them in the network command trace
4. Warning 38005:

 ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/1/1f0780e07f7d658c761fcc0b2bbf7e6f38b0be29.png)

Think about what happens when you power on the controller…the axis control installed on the drive is trying to keep the actual position of the motor, but in your case automatically you get the warning “Speed is too high during switch on”…so what about Commutation offset? are you sure is 0 rad? Can you do a phasing test just to be sure about that value?  
This step + additional info are described on this post [https://community.br-automation.com/t/sew-motors-parameter-for-acopos/3280](https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcommunity.br-automation.com%2Ft%2Fsew-motors-parameter-for-acopos%2F3280&data=05%7C02%7Cvalerio.manenti%40us.abb.com%7Cf54906edf16b40a6980a08dea44f79f7%7C372ee9e09ce04033a64ac07073a91ecd%7C0%7C0%7C639128858429214760%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=OjOJDLPsU5wvbU%2FlJntpU7RgXaRSQM8T1k7ni%2FGT22A%3D&reserved=0)

Hi @thachnt ,

you have to determine the commutation offset, too.

Your ‘0’ might be false.

This can be done using a ‘Phasing’ procedure. The ‘phasing mode’ depends on the type of the motor encoder.

Your resolver is most likely an absolute encoder and ‘stepper mode’ is reasonable for this.

‘stepper mode’ also checks the motor polepairs and the correct encoder rotation.

[Phasing](https://help.br-automation.com/#/en/4/ncsoftware%2Facp10_drivefunctions%2Fantriebsidentifikation%2Feinphasen%2Feinphasen_.html)

However, your motor might start working if you just swap two of its phases.

Hi @thachnt ,  
Any update?  
At the end have you spined your motor?  
Thanks
