AMI81xx Smart servo drive with integrated output stage

AMI81xx | Smart servo drive with integrated output stage

In the compact Drive Technology product range (up to 48 V DC), the newly integrated AMI812x servo drive combines servomotor, output stage and fieldbus connection in a space-saving design for all motion requirements in the power range up to 400 W. As an EtherCAT slave, the AMI812x can be placed directly on the machine without control cabinet and without upstream I/O level, whereby compact machines without control cabinets can be implemented. On introduction to the market, the series consists of three overall lengths of the flange size F2 with standstill torques from 0.5 to 1.1 Nm. The AMI812x is optionally available with an absolute multi-turn encoder without battery buffering and with an optional backlash-free holding brake. With the additional shaft seal, it attains the high protection class IP 65 and is suitable for all installation positions.

The fast control technology, based on field-oriented current and PI speed control, supports fast and highly dynamic positioning tasks. The monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent or the motor load via the calculation of an I²T model, offers maximum operational reliability. The operating state is displayed by the integrated status LEDs. Electronics and power are supplied via the M12 power interface, while the M8 bus interface for EtherCAT offers a second port for simple cascading of the topology. The I/O interface (M8) enables the direct connection of two sensors or actuators in the 24 V DC signal range up to 0.5 A. The connection cables are available with a straight and angled outlet. The AMI812x is configured as a complete EtherCAT slave via TwinCAT or the EtherCAT master. The AMI812x is fully integrated in the TE5910 TC3 Motion Designer. Extremely high torques can also be achieved with the matching planetary gear unit from the AG2250 series.
