Abstract
A method for checking a speed system of a motor-driven apparatus is proposed. In the absence of a speed signal, a first aspect provides for a control device to send a test signal via the speed system, the test signal being expected at an input of the control device. If the test signal is not detected, a fault in the speed system is identified.
