We consider Wada's representation as a twisted version of the standard action of the braid group, Bn, on the free group with n generators. Constructing a free group, Gnm, of rank nm, we compose Cohen's map BnBnm and the embedding BnmAut(Gnm) via Wada's map. We prove that the composition factors of the obtained representation are one copy of Burau representation and m1 copies of the standard representation after changing the parameter t to tk in the definitions of the Burau and standard representations. This is a generalization of our previous result concerning the standard Artin representation of the braid group.
