We propose a system of nonlinear integral equations (NLIE) which describes the thermodynamics of the U_q(sl(<r+>^^^^1)) Perk-Schultz model. These NLIE correspond to a trigonometric analogue of our previous result, and contain only r unknown functions. In particular, they reduce to Takahashi's NLIE for the XXZ spin chain if r=1. We also calculate the high temperature expansion of the free energy. In particular for r=1 case, we have succeeded to derive the coefficients of order O((J/T)^<99>).
