We suggest a system of dynamical difference equations with respect to $λ$ compatible with the KZ equations. The dynamical equations are constructed in terms of intertwining operators of $\g$-modules.23 pages, AmsTeX, third version, some misprints were correctedQuantum Algebra17B10, 81R05, 39A05text
