8EI4X5MWT10.0000-1 by B & R Automation

The 8EI4X5MWT10.0000-1 is a servo drive module produced by B & R Automation within the 8EI Servo Drives series. The unit belongs to the ACOPOS P3 8EI servo drive family and functions as the power interface between a control processor and multiple permanent-magnet motors across compact machine platforms. Its role in industrial automation is to supply regulated current and to implement safety shutdown so coordinated multi-axis motion can be executed without external relays in packaging, assembly, and material-handling equipment.

Electrical and mechanical limits show where the module fits in a cabinet. The drive accepts input supplies of 3× 200-230 VAC or 1× 110-230 VAC, allowing either three-phase or single-phase mains on global plant networks. Under continuous duty, it delivers 4.5 A (rms) per axis, a rating that suits low-to-mid power servomotors used on pick-and-place axes and feed rolls. Installation is simplified by wall mounting, so heat sinks line up with vertical airflow channels inside the enclosure. Functional safety is embedded through hardwired STO safety linked to the encoder feedback, which removes torque-producing energy in less than a millisecond. The module is supplied in the standard module option configuration, which keeps the feature set straightforward.

Scalability is provided in software, and the same hardware can be configured as a 1-axis capability or a 2-axis capability beside its default three-axis profile, allowing the channel count to match machine expansion without rewiring power. For field terminations, connector set 1 (single-row) is included to provide keyed plugs for motor power, brake, and feedback, while the unit comes without connector set 2 (two-row) to keep the overall width minimal for dense rack layouts. No internal braking resistor is installed, no front cover is shipped, and no plug-in option is delivered, so braking energy dissipation and panel protection must be handled by external components mounted elsewhere in the cabinet.
