By this method, the masses and the frictional forces of all movably interconnected installation parts are referred to the door leaf (2) in a sliding door system (1) and ascertained numerically with the aid of the closing weight (G). For this purpose, the door leaf (2) is subjected to an opening learning travel (öL) and a closing learning travel (SL) and in that case guided without drive over a respective test section TS1 and TS2 and a first energy balance (EB1) and a second energy balance (EB2) respectively are set up from then measured kinematic parameters (v1, v2, s1) and (v3, v4, s2). The energy balances (EB1, EB2) contain the potential energy (Ep) of the closing weight (G) with positive or negative sign and in combination result in special formulae for the numerical values of the dynamic mass (md) and the mean frictional force (Fr*) of the sliding door system (1). The microprocessor (3.1) and the incremental transmitter (3.2) of the door drive (3) serve for the measuring, storing and processing of the kinematic parameters as well as for the computation of the numerical values of the dynamic mass (md) and the mean frictional force (Fr*). The method is generally applicable to mass systems and their physical characteristic values and is suitable particularly for the ascertaining of the closing speed (vsmax), which is the maximum permissible for reasons of safety technique, of sliding and pivoting doors.
