US 12,237,793 B2 · Device and method for operating a drive system

Abstract

A drive system includes a frequency converter, a drive unit, and a power supply. The drive unit includes an electric motor and a further component, including a sensor element, actuator element, and/or data storage element. The frequency converter supplies the further component of the drive unit with energy via at least the power supply. The frequency converter is adapted to obtain a first piece of information about the maximum available electrical energy of the power supply and to obtain a second piece of information about the electrical energy requirement of the further component of the drive unit. The frequency converter is adapted to check the plausibility of the first piece of information with respect to the second piece of information. The decision-making criterion for the plausibility check is formed by a logical comparison of the first piece of information with the second piece of information. The frequency converter is configured to adapt the system state of the drive system in accordance with the result of the plausibility check.
