If it is a constant hp application, it would be Delta - High speed and Wye - Low speed.
You need to contact the motor supplier to know which connection is applicable (is there not a nameplate on this motor that tells you how to connect it for both speeds ?)

RE: 3 phase 6 lead 2 speed european ac motor help
your connections will depend on the type of windings in the motor....the above connections by kuldipkenya are for a motor with a tapped winding..which can be identified by a continuity test between your terminals...on this type of motor there will be a circuit between all 6 output leads!!!
the other type is a dual wound motor with two completely seperate windings!! ie..U V W and X Y Z with circuits between themselves only...u-v-w x-y-z and nothing between the two windings...
if that is the case , it is as simple as supplying one winding or the other....leaving the other windings open.
hope this helps
