We derive analytically the pinning potential and the pinning barrier of kinks due to discreteness of lattices for the Remoissenet-Peyrard substrate potential by means of the residue method. The theoretical analysis in the low discreteness effect regime is compared in detail with numerical results of Peyrard and Remoissenet [Phys. Rev. B 26, 2886 (1982)], yielding a very satisfactory agreement.
