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