8EI4X5MWT10.0500-1
The 8EI4X5MWT10.0500-1 from B & R Automation belongs to the 8EI Servo Drives series, representing a high-performance solution for industrial automation. This device is a 3-axis module in the ACOPOS P3 8EI servo drive family, configured for both single-phase and three-phase operation at 3x 200-230 VAC or 1x 110-230 VAC. Housed in a robust enclosure with wall mounting capability, it features an integrated internal braking resistor to manage rapid deceleration events without external hardware. The drive supports a continuous current of 4.5 Aeff and delivers up to 5 kVA of maximum apparent power, ensuring ample headroom for demanding motion profiles.
Technical prowess is evident through its substantial DC bus capacitance of 1880 µF, complemented by a total input capacitance of 5507 µF, which buffers energy and stabilizes voltage during high dynamic load changes. An initial inrush of 22 A is managed reliably, while the logic section runs on 24 VDC (±25%), providing stable power to control circuits, fans, I/O interfaces, and sensors. The drive operates across mains frequencies of 0 Hz to 60 Hz (±4%), enabling seamless global deployment. An integrated EMC line filter compliant with Category C3 minimizes electromagnetic emissions and enhances compatibility with sensitive equipment. Its hardwired STO safety technology with encoder option ensures functional safety and secure real-time feedback.
Operational efficiency and reliability are further enhanced by its design. The module requires a 60-second reset delay after power-off to protect internal capacitors and electronic components. A modest base current draw of 1.2 A maintains essential functions, while compatibility with TN-S and TN-CS power distribution systems simplifies installation within varied infrastructural standards. The drive’s no plug-in module architecture and standard module option reduce mechanical complexity and improve serviceability. For applications where space is critical, the ability to use this unit as a 2-axis module provides flexible configuration options without additional hardware.
Integration into existing automation platforms is straightforward, thanks to the drive’s >>mounting<< and connection provisions. Although connector set 1 (1-row) is not included, standard industrial cabling practices apply, and no customized options are required for typical deployments. The strength grade A2-70 stainless steel mounting flange, featuring a Rockwell B71 min hardness and tensile strength of 700 MPa, ensures secure mechanical interfaces under high torque loads. Whether used in packaging machines, CNC equipment, or robotic cells, the 8EI4X5MWT10.0500-1 delivers dependable performance and robust integration for industrial automation environments.
