  The gravitation interaction between particles is taken into account in
central configuration model. After that, the resonance perturbation of the
particle of the central configuration by distant satellite is considered in the
restricted 3-body problem approach. A shift between simple mean motion
resonances and parametric resonance zones is derived. This shift depends upon
mass satellite and central configuration properties. Unexpectedly, the
resonance structure depends only on particle density and number of particles in
the central configuration, but not depends on particles mass. Then, the system
of few non-interacted planar central configurations is considered. The
resonance structure, which follows from parametric instability, is more
abundant than for simple mean motion resonance case. The areas of parametric
instability restrict stable central configuration, placed in exact
commensurability, from both sides. The possible application to the planetary
ring structure is discussed.
