Good afternoon. I looked around the forum and did a search, and I apologize if this question has already been asked and answered. For the VFD included in the ATC system, what is the input voltage for the VFD? Some VFD’s allow for both 110 and 220. Is the PWN vfd set up to allow for either input voltage? If the capability is there, would I be able to select the input voltage to meet my needs? thank you.

Thanks Bjtroupjr, I managed to get a response from support. Depending on the spindle/ATC kit you order, the input voltage for the VFD is ‘locked’ and cannot be changed. So a 110 spindle would use a VFD with 110 single phase input, and a 220 spindle would use a vfd with 220 single phase input.
For those international customers… it is possible to adjust the 220v input up to 240 for international customers. It’s one of the vfd settings but that is the extent of the adjustability.
110v can go up to 120v iirr… but i believe this is simply within the acceptable deviation range.
