We present the $v_2$ measurement at midrapidity from Au+Au collisions at$\sqrt{s_{NN}}=$ 7.7, 11.5, 19.6, 27, 39 and 62.4 GeV for inclusive chargedhadrons and identified hadrons ($\pi^{\pm}$, $K^{\pm}$, $K_{S}^{0}$, $p$,$\bar{p}$, $\phi$, $\Lambda$, $\bar{\Lambda}$, $\Xi^{-}$, $\bar{\Xi}^{+}$,$\Omega^{-}$, $\bar{\Omega}^{+}$) up to 4 GeV/$c$ in $p_{T}$. The beam energyand centrality dependence of charged hadron $v_2$ are presented with comparisonto higher energies at RHIC and LHC. The identified hadron $v_{2}$ are used todiscuss the NCQ scaling for different beam energies. Significant difference in$v_{2}(p_{T})$ is observed between particles and corresponding anti-particlesfor $\sqrt{s_{NN}} <$ 39 GeV. These differences are more pronounced for baryonscompared to mesons and they increase with decreasing energy.
