Function
A synchronous motor drives the drive shaft with a mounted camshaft via a gear. The
camshaft actuates end switches and auxiliary switches. The switch position of each end
switch and auxiliary switch can be adjusted by an assigned cams disk within the
running range. Some actuator versions are equipped with electronic switching modules
that perform additional functions in connection with the end switches and auxiliary
switches and external units, such as controllers (refer to Circuit diagrams).
