Abstract
The invention relates to an arrangement for identifying an electrical line interruption during operation of a drive system (), which comprises two parallel-connected DC motors (), which are mechanically coupled to one another by means of a part that is to be driven, a driver for driving the two parallel-connected DC motors () and a measuring device for detecting different electrical variables of the drive system (). The measuring device comprises a rotational speed determination apparatus () for determining the rotational speed of the two DC motors () and for supplying a piece of rotational speed information representing the rotational speed. The measuring device further comprises a current measuring apparatus () for determining a summation current flowing in the two DC motors () and for supplying a piece of current information representing the summation current and a voltage determination apparatus () for determining the terminal voltage of the two DC motors () and for supplying a piece of voltage information representing the terminal voltage. A computation unit () is designed to ascertain a motor parameter (k) for the drive system () from the voltage information, the current information and the rotational speed information and to compare said motor parameter with a setpoint value (k) of the motor parameter (k), wherein the presence of a line interruption to one of the two DC motors () can be inferred from the result of the comparison.
