The newly launched AMI812x integrated servo drives series from Beckhoff is extending the compact drive technology portfolio up to 48 Volts DC by the usage of very compact devices for distributed field installation. These drives are optimum for automation outside of control cabinets in the motion power range up to 400 W due to the integration of servomotor, output stage, and field-bus connection.
As an EtherCAT slave, the AMI812x integrated servo drive is used by placing it directly on a machine without a control cabinet and in the absence of upstream I/O level making way for the implementation of very compact machines without control cabinets. This servo drives series consists of three overall lengths in the F2 flange code with standstill torques in the range of 0.5 to 1.1 Nm. The optional parts of these servo drives are a multi-turn absolute encoder without battery backup and with a backlash-free holding brake. An additional sealing ring enables the servo drive to have a high IP 65 protection rating suitable for all installation positions. To integrate the STO safety function, the TwinSAFE logic is used.
On the basis of vector current and PI speed control, fast control technology supports extremely dynamic positioning tasks
There are many monitoring options such as overcurrent or motor utilization through a calculation of an I2T model and over or under voltage to achieve high operational reliability. The integrated status LEDs provide the operating state.
The M12 power interface supply the electronics and motor. The M8 bus interface for EtherCAT renders a second port to do simple cascading in an EtherCAT daisy chain. Beckhoff has planned to introduce a motor version with EtherCAT P connection. The I/O interface (M8) makes it possible to have a direct connection of two sensors or actuators in the 24 V DC signal range up to 0.5 A. The connection cables maybe with straight or angled outlets. In the AG2250 series, the matching planetary gear unit provides very high torques.
