Abstract
A method for controlling an installation for a revolving passenger transport comprised of steps or pallets moving along a transport path that includes a plurality of drives. At least one drive is arranged in a reversing area and at least one further drive is arranged in an area of the transport path. Each drive is actively connected to a frequency converter. All of the frequency converters are monitored by a higher-order control. A defined drive pattern is memorized in the higher-order control. Measured values of the drives are transmitted to the higher-order control by individual frequency converters. The measured values are compared in the higher-order control with respect to each other. In case of divergences from the memorized drive pattern of the respective frequency converter, the respective frequency converter which diverges from a comparative value is corrected with aid of the higher-order control.
