We study parameter space in the axion monodromy inflation corrected by dynamically generated terms involving with the axion .
The potential has the linear term with multiple sinusoidal functions , which play a role in generating modulations .
We show that this potential leads both to a large tensor-to-scalar ratio r _ { T } \sim 0.16 and to a large negative running of spectral index \alpha _ { s } \sim - ( 0.02 - 0.03 ) , ameliorating the tension between the result of the PLANCK and that of the BICEP2 .
To realize these results , a small hierarchy among dynamical scales is required whereas the decay constants in sinusoidal functions remain sub-Planckian in this model .
We discuss also reheating process after the inflation in a bottom-up approach .
