LYMAN, S.C. - May 22, 2008 - A new AS-Interface offering improved diagnostic capabilities is now standard with MOVIMOT® C,
SEW-EURODRIVE's line of gearmotors with integral frequency inverters. Designed for real-time communications at the sensor
or actuator level, AS-Interface provides fail-safe connectivity under the most challenging ambient conditions. It links easily
to higher-level fieldbus and Ethernet networks.
The integration of AS-Interface, an unshielded two-wire bus, makes it easy to connect sensors and actuators to distributed
control systems using master and slave topologies. Up to 31 slaves can be connected to a drive system incorporating multiple
MOVIMOT® C gearmotors. Maximum communications cycle time is 5 ms for 31 stations. Maximum line length is 100 meters, or 300
meters with a repeater.
MOVIMOT® C gearmotors feature a built-in LED for quick display of machine diagnostics and motor protection information. Each
MOVIMOT® can accommodate up to two sensors.
The new MOVIMOT® C gearmotor with integrated AS-Interface is a multiple-speed drive with integrated brake management and soft
start capabilities. It features 16 scalable speed specifications, including clockwise and counterclockwise direction of rotation.
Power range is from 0.37 to 3.0 kW.
Actuator-sensor interfaces are a cost-effective alternative to conventional fieldbus systems, especially in conveyors and
other systems using decentralized control architectures. Installation is limited to connecting the AS-Interface cable, which
enables signal transmission as well as 24 volt power supply to the system. Power supply is daisy-chained from drive to drive
in the form of a network bus. This installation structure provides a flexible and cost-efficient solution using prefabricated,
