Abstract: A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.
