Spindle runs backwards

Help!

I think my Chuck(Spindle) is running backwards!
When the chuck is viewed end on it is running counter clockwise. It should be running clockwise.

My VFD is controlled from 0-5Vdc and the speed runs ok from 0 through 1800rpm in keeping with whatever I feed into the M3  i.e M3 S500 I get 500rpm

Any ideas why this is happening, Looks like I have some incorrect setting.

Thanks

Sorted,
I reversed two of the connections on my spindle drive and all was well.
Thanks
