In this method and with this device for the regulation of a drive, apart from an existing drive regulation (1) provided with subordinate rotational speed and torque regulation, a superimposed rapid rotational speed regulation (2) is provided for holding of th e load after opening of the holding brake. In addition, computation of the load in a lift cag e (5) is possible by means of a processing unit (3) with the aid of a target torque value (TMSOLL) and an actual rotational speed value (vist) Thereby, the drive can be so regulat ed with little material effort that jerk-free starting is made possible. Furthermore, ap preciable cost savings result, since no additional hardware, such as load-measuring devices at the lift cage (5), is needed. Beyond that, the lift cage construction is simplified and e xpensive rebuilding of the cages during modernisation of lift installations becomes super fluous.
