Abstract
The invention relates to a method for detecting undesired operating conditions of a driving device. A sensor () that is transformer-coupled between a stator side and a rotor side is triggered by a control circuit () for detecting a position value or a rotational speed value of the drive mechanism. An error signal (F) is emitted, if an undesired operating condition occurs. A test signal (ε) is supplied to a safety monitoring device () in order to determine and emit this error signal (F), said test signal being also supplied to the control circuit (). There, the test signal (ε) acts as an unbalance and is checked as regards its presence in the safety monitoring device.
