Method and device for actuating an actuator device, and actuator device

A method of actuating an actuator unit (102) of a roll stabilizer for a vehicle (100), the actuator unit (102) has a supply line port (118) for providing a supply voltage, a converter (112) for providing an AC voltage using the supply voltage, and at least two phase lines (114, 116;

• 314) for providing alternating voltage to actuator ports (132, 134) of an actuator (110) operable using AC voltage, and the method comprising:
• importing (201) an interrupt signal (140) indicating either an interruption (130) of a provision of or a deviation from the supply voltage at the supply line port (118);
• and
• providing (203) a protection signal (142, 144, 146, 148), using the interrupt signal (140) at an interface, to protection equipment (152, 154, 156, 158), which is designed to at least partially prevent a generator voltage that either is fed or can be supplied to the phase lines (114, 116;
• 314) from being transmitted via the actuator ports (132, 134) in response to the protection signal (142, 144, 146, 148).

A device (104) for actuating an actuator unit (102) of a roll stabilizer for a vehicle (100), the actuator unit (102) having a supply line port (118) for providing a supply voltage, a converter (112) providing an AC voltage using the supply voltage, and at least two phase lines (114, 116;

• 314) providing alternating voltage to actuator ports (132, 134) of an actuator (110) operable using AC voltage, the device comprises:
• an import device (160) for importing an interrupt signal (140) indicating an interruption (130) of a provision of the supply voltage at the supply line port (118);
• and
