750W EtherCAT Servo Motor 80mm with 17bit Absolute Encoder (IRSV80-30-75-48-17BC-RC/EC)

Distributed servo control has traditionally meant a drive cabinet for every axis. The IRSV80-30-75-48-17BC-RC/EC changes that by integrating a 750W EtherCAT Servo Motor 80mm with its drive in a single housing, powered from 48 VDC and carrying a 17-bit absolute encoder for true position feedback.

Fieldbus Servo Axis in a Single Housing

The IRSV80-30-75-48-17BC-RC/EC integrates a 750 W servo motor and drive in an 80 mm frame, with a rated current of 21.0 A from a 48 VDC supply. It is one of the higher-power integrated units in the fieldbus series. Because the encoder, motor, and power stage share one housing, the separate encoder cable, motor power cable, and signal wires of a conventional servo system are eliminated. The machine builder connects only a DC supply and the fieldbus line, which cuts wiring work and the space needed in the control cabinet.

Built-In Protection and closed loop Control

The unit includes protection against overcurrent, overvoltage, undervoltage, and excessive position deviation. The 17-bit absolute encoder reports absolute position at power-up, removing the need for homing on multi-axis CNC and battery manufacturing stations where downtime for referencing is expensive.

Where 750 W Integrated Fieldbus Units Fit

The output level and bus connectivity suit CNC machine tools, packaging and textile lines, battery manufacturing equipment, and AGV/AMR systems that run on 48 VDC and need deterministic bus control. EtherCAT provides synchronized motion on larger machine networks, while CANopen and RS485 cover simpler distributed layouts. Communication is supported over RS485 plus CANopen or EtherCAT through an RJ45 network port.
