ABSTRACT:
A full-bridge circuit includes a first, second, third and fourth switch element. According to the method the checking includes at least one measuring process. For the at least one measuring process either only the second or only the third switch element or only the first and the second switch element or only the third and the fourth switch element is/are switched on. At least one recording time in each measuring process, a parameter is recorded which is representative of an electrical current flowing through a measuring resistance Rm. Depending on the recorded parameter and the switched-on switch element(s), a fault or lack of fault is recognized in an inductive load L of an electromechanical converter in the full-bridge circuit. A duration for the checking is set such that during said duration an idle condition for the electromechanical converter is maintained.
