Beckhoff’s AMI812x device series combines servomotor, output stage and fieldbus connection in a compact form factor.

Beckhoff unveiled its AMI812x series of integrated servo drives that integrate servomotor, output stage and fieldbus connection in the motion power range up to 400W. As an EtherCAT device, the servo drive can be placed directly on the machine without a control cabinet or upstream I/O. The AMI812x series includes three overall lengths in the F2 flange code with standstill torques from 0.5 to 1.1 Nm. Options include a multi-turn absolute encoder without battery backup and with a backlash-free holding brake. With an additional sealing ring, the servo drive achieves a IP65 protection rating and is suitable for all motor installation positions. STO safety functionality can be integrated as an option via TwinSAFE Logic. Power is supplied via an M12 interface. The M8 bus interface for EtherCAT offers a second port for simple cascading in an EtherCAT daisy chain and enables direct connection of two sensors or actuators in the 24 V DC signal range up to 0.5 A.
