Beschreibung
Zusammenfassung:	Proposed is a device for operating an actuator-motor drive (11) which includes a relay-controlled switchover device (12) for the clockwise/anticlockwise running of the actuator motor (10). A first semiconductor switch (23) is fitted to feed current to a first relay winding (15) and a second semiconductor switch (25) to feed current to a second relay winding (16). A third semiconductor switch (26) is connected in series with the first relay winding (15) and with the second relay winding (16). Switching the third semiconductor switch (26) on and off enables the current to the relay windings (15, 16) to be allowed to pass or to be shut off. Shorting in either of the first two semiconductor switches (23, 25) has no effect on the drive (11). No unintentional control operation takes place.
