8EI2X2MWDS0.0700-1 by B & R Automation

B&R Automation's 8EI2X2MWDS0.0700-1 belongs to the 8EI Servo Drives series and is supplied as a compact motion-control module for the ACOPOS P3 8EI servo drive platform. In multi-axis factory lines, this unit interfaces with a central controller to regulate torque and position across paired motor channels, replacing discrete single-axis amplifiers and reducing cabinet space. Its role is to deliver closed-loop speed and current control for industrial actuators such as pick-and-place arms, gantries, and conveyors.

Rated for a continuous phase current of 2.2 Aeff, the module operates from 3x 200-230 VAC or 1x 110-230 VAC, allowing either three-phase or single-phase supplies. It is a 2-axis module, and the same hardware family is also offered in single-axis versions for machines with fewer controlled channels. The integrated internal braking resistor dissipates regenerated energy, eliminating an external brake chopper during normal deceleration. Installation uses wall mounting, and the absence of a plug-in module keeps the footprint shallow. A standard, non-customized option is preset, and Connector Set 1, the single-row arrangement, is intentionally omitted to leave front-panel space for field power terminals.

The safety architecture is extended by SafeMOTION, which relies on the built-in digital encoder to support certified STO, SS1, and speed-limited modes without external relays. When higher pin counts are required for encoder or brake feedback, the optional Connector Set 2 (2-row) mounts directly on the faceplate and aligns with preformed cable harnesses. For machines that exceed two synchronized axes, the drive family is also available as a 3-axis module, preserving the same 50 mm width per channel. Included with the module is a front cover, which shields low-voltage terminals from debris while keeping diagnostic LEDs visible; this enclosure detail complements the EMC-conscious grounding scheme implemented on the baseplate and helps the module meet cabinet ingress targets.
