Integrated servo drive for automation outside of control cabinets

By OEM Update Editorial March 31, 2020 5:46 pm IST

The new AMI812x series of integrated servo drives expands the compact drive technology portfolio (up to 48 V DC) from Beckhoff by extremely compact devices for distributed field installation. The integration of servomotor, output stage and fieldbus connection in a space-saving design makes the drives ideal for automation outside of control cabinets in the motion power range up to 400 W.

As an EtherCAT slave, the AMI812x integrated servo drive can be placed directly on the machine without a control cabinet and without upstream I/O level, allowing for the implementation of highly compact machines without control cabinets. At market introduction, the AMI812x series includes three overall lengths in the F2 flange code with standstill torques from 0.5 to 1.1 Nm. The AMI812x is optionally available with a multi-turn absolute encoder without battery backup and with a backlash-free holding brake. With an additional sealing ring, the servo drive achieves high IP 65 protection rating and is suitable for all installation positions. The STO safety function can be integrated as an option via the TwinSAFE Logic.

The fast control technology, based on vector current and PI speed control, supports highly dynamic positioning tasks. Numerous monitoring options, such as over and undervoltage, overcurrent or motor utilisation via calculation of an I²T model, offer high operational reliability. The operating state is indicated by integrated status LEDs.
