Abstract
A method for detecting a short circuit to ground or to the operating voltage of a signal line () of a resolver () has the following steps: —measuring the potential of the signal lines () of the receiver coil () with respect to ground at two sampling times (R and F) provided symmetrically at the middle of the excitation period; —calculating an offset value for a signal line pair () by calculating the average value of the four measured values (U, U, Uand U) for the associated receiver coil (); and —identifying a short circuit and the potential to which the short-circuited line is connected in that the offset value is compared to threshold values.
