Beschreibung
Zusammenfassung:	The invention relates to a method (300) for external monitoring of power electronics (450), wherein the power electronics (450) are actuated by means of first control electronics (460) and the method (300) is carried out by independent, second control electronics (420). The method comprises the following steps: determining (320) a parameter (P); determining (330) the difference (D) of between the determined parameter (P) and a target value (S); actuating (340) the power electronics (450) if the amount of the difference (D) exceeds a threshold (G).
