8EI4X5HWDS0.0300-1 by B & R Automation

The 8EI4X5HWDS0.0300-1 is a servo drive produced by B & R Automation for the 8EI Servo Drives series. It belongs to the ACOPOS P3 8EI servo drive line. As a servo drive, it delivers regulated power to motion axes and exchanges feedback with the digital encoder inside the connected motor so that position, velocity, and torque can be controlled in real time within industrial automation cells. The unit is intended for coordinated axis control in machinery that requires fast response and stable closed-loop motion. Encoder signals are processed continuously so the axis can correct speed and position errors as load conditions change.

This model operates on a supply of 3x 200-480 VAC, allowing installation on low- to medium-voltage mains without an external transformer. It provides a continuous phase current of 4.5 Aeff, which is the steady-state load the unit can supply without overheating. The hardware is delivered as a 2-axis module, so two independent motor windings can be energized from one frame to conserve cabinet space. Integrated functional safety is available through SafeMOTION, which enables certified stop, limited speed, and safe direction monitoring through the digital encoder interface. Mechanical installation is simplified by wall mounting, which positions the heat sink against the panel for convection while keeping the front accessible. The drive has no internal braking resistor, so excess regenerative energy must be routed to an external resistor or fed back to the DC link.

Electrical terminations use the Connector Set 2 (2-row) layout, while Connector Set 1 is not fitted. The two-row arrangement keeps the connection points organized on the front of the unit. A front cover is included to protect the terminals during operation. No plug-in module ships with the unit, so any future option card must be sourced separately. The module is supplied in a standard configuration without customized options or series-specific add-ons.
