Abstract

The invention relates to a method for actuating an actuator unit ( 102 ) of a roll stabilizer for a vehicle ( 100 ), wherein the actuator unit ( 102 ) has a supply line port ( 118 ) for supplying a supply voltage, a converter ( 112 ) for supplying an alternating voltage using the supply voltage, and at least two phase lines ( 114, 116 ) for supplying the alternating voltage to actuator ports ( 132, 134 ) of an actuator ( 110 ) which can be operated using the alternating voltage, comprises a step for importing an interrupt signal ( 140 ), which indicates an interruption ( 130 ) in the provision of the supply voltage or a deviation from the supply voltage at the supply line port ( 118 ) and a step providing ( 203 ) a protection signal ( 142, 144, 146, 148 ) in response to the protection signal ( 142, 144, 146, 148 ) at an interface having protection equipment ( 152, 154, 156, 158 ) using the interrupt signal ( 140 ) in order to at least partly prevent a generator voltage from being transmitted, which is fed or can be fed into the phase lines ( 114, 116; 314 ) via the actuator ports ( 132, 134 ).
