8EI044HWS10.A000-1 by B & R Automation

The 8EI044HWS10.A000-1 servo drive is produced by B & R Automation and belongs to the 8EI Servo Drives series. Inside the ACOPOS P3 8EI platform, it acts as a dedicated axis controller that supplies regulated current to a connected motor for position or speed control in industrial automation cells. The module bridges the motion controller and the power stage, translating commands into precisely timed switching patterns that drive mechanical actuators on packaging lines, conveyors, or robotic tooling. This arrangement lets the drive respond quickly to command changes during indexing, synchronized transport, and other repetitive motion tasks.

It draws power from a three-phase supply rated at 3x 200-480 VAC and can deliver a continuous output of 44 Aeff, providing headroom for medium- to high-torque motors across that voltage range. Motion feedback is handled through the integrated Resolver 1x interface, so the controller receives rotor position on every cycle. Functional safety is implemented by hardwired STO safety technology, which removes torque rapidly when a stop request is asserted. The housing is prepared for wall mounting, which supports direct installation on the cabinet structure and helps transfer heat to the mounting surface. This drive is supplied without an internal braking resistor, so external dynamic-braking hardware is required when deceleration energy must be dissipated.

The signal and power terminations are grouped into a 1-row connector set, while the second connector row is omitted to keep wiring straightforward and conserve panel space. Because the design is a 1-axis module, one drive controls one motor axis. The hardware is supplied in the standard option configuration, with no front cover and no connector set 2 installed. This layout keeps the front of the unit simpler and concentrates cable access in a single connection area.
