Post a picture of the motor rating plate please

Also, what is the application?

 

[telectrix]

it's quite likelythat a motor that size will be 415V 3 phase star and 230V 3 phase delta. if so wiring it in delta will fry the motor. to be safe, I advise wiring in star config. unless the rating plate says otherwise.

You have a VSD with 400 3ph input and 400 3ph output, as long as your motor has a 400v option which I suspect it almost certainly will then there is no real advantage to setting the VSD up as though it was running a 230v 3ph.

Yes thanks you. I using star config and the system works fine ?
