The AMI812x series of integrated servo drives from Beckhoff comprises extremely compact devices for distributed field installation. Thanks to the integration of servomotor, output stage and fieldbus connection in a space saving design, the drives are fitted for automation outside of control cabinets in the motion power range up to 400 W. The AMI812x includes three overall lengths in the F2 flange code with standstill torques from 0.5 to 1.1 Nm.
As an EtherCAT slave, the AMI812x can be placed directly on the machine without a control cabinet and without upstream I/O level, enabling the implementation of highly compact machines without control cabinets. It handles highly dynamic positioning tasks through the fast control technology which is based on vector current and PI speed control. Electronics and motor are supplied via the M12 power interface. The M8 bus interface for EtherCAT offers a second port for simple cascading in an EtherCAT daisy chain. In addition, the introduction of a motor version with EtherCAT P connection is planned. The I/O interface (M8) enables direct connection of two sensors or actuators in the 24 V DC signal range up to 0.5 A.
