A control device for operating an electric motor, in particular a steering system, includes a power electronics, a primary driver unit provided for actuating the power electronics in a normal operating state, and a secondary driver unit connected in parallel to the primary driver unit and provided for actuating the power electronics in at least one fault operating state in which a malfunction and/or failure of the primary driver unit occurs. The secondary driver unit comprises a power source having an adjustable current strength for controlling a switching state of at least one circuit breaker of the power electronics. An absolute value of the power source in the normal operating state is set to a first value which is below a first limit value, and in the at least one fault operating state it is set to a second value which is above a second limit value.
