Vortices driven with both a transverse and a longitudinal ac drive which are out of phase are shown to exhibit a novel commensuration-incommensuration effect when interacting with periodic substrates. For different ac driving parameters, the motion of the vortices forms commensurate orbits with the periodicity of the pinning array. When the commensurate orbits are present, there is a finite dc critical depinning threshold, while for the incommensurate phases the vortices are delocalized and the dc depinning threshold is absent.
