I have a dual-rated SEW Eurodrive motor that I would like to use for a small project I 've been wanting to do for some time but I have a concern. The motor is rated 230YY or 400Y. I need variable speed anyway so it will be run off of a VFD. The available voltage is 480 and I don't want to buy a transformer. If I set P0.0 at 400, would I have to do anything else to limit the voltage to the motor? P2.07 is minimum output voltage but I don't see a maximum parameter. This is a project that I will only be allowed to do if I can use parts I have on hand and I don't want to go to all the mechanical work if it is not feasible electrically. TIA

As long as P6.04 is left at the default of 00, then the drive will regulate and limit the voltage to what you have set in P0.00 at the motor base frequency ( P0.02).

That makes sense, thanks. Just for the sake of conversation, if auto voltage regulation is turned off, would the output voltage be limited to the input voltage?

Correct. Output voltage will only be limited by the input voltage with AVR disabled.

Thanks very much.
