8EI8X8HWT10.0700-1
The 8EI8X8HWT10.0700-1 is a servo drive module produced by B & R Automation and assigned to the 8EI Servo Drives series. It functions as the power and control interface between an AC synchronous motor and a higher-level PLC. The module delivers closed-loop motion commands for multi-axis machinery in industrial automation. By combining power conversion and motion regulation in one unit, it supports coordinated torque, speed, and position control from the same cabinet location. This makes it suitable for machines that need several synchronized axes without using a separate housing for each channel.
This unit is configured as a 3-axis module, allowing three coordinated motor channels to be driven from one enclosure. Each axis can draw up to 8.8 Aeff of continuous current, which indicates the sustained thermal load the power stage can handle without derating. The input supply accepts 3x 200-480 VAC, so the same hardware can be connected to common low- or medium-voltage plant mains without tap changes. For functional safety, hardwired STO safety technology with encoder disables drive output within milliseconds when the safe torque-off chain is opened. Dynamic deceleration energy is dissipated by an integrated internal braking resistor, reducing the need for an external resistor bank in many indexing applications.
Mechanical installation is simplified by wall mounting holes on the chassis. The design is also available as a 1-axis module or a two-axis variant when cabinet space or shared power requirements differ. A dual-row power and feedback interface identified as Connector Set 2 (2-row) is present, while the single-row connector set is omitted to conserve height. A formed sheet-metal front cover guards the bus capacitors and can be removed for inspection. The drive ships in a standard configuration without additional plug-in cards or extra I/O. That layout keeps the module straightforward for installations that rely on fixed connections and external control wiring.
