Abstract
In a method and a circuit for the monitoring of electromotive setting elements which are connected to a bridge output stage, the actual values of the currents in the branches of the bridge are compared with the desired values which apply to the corresponding state of switching. Depending on the result of the comparison and the state of switching of the bridge output stage, an error possibly present is read from a table. It should be emphasized, in particular, in this connection that with only one bridge circuit, two motors which are connected in parallel can be completely monitored.
