Product Description:
The 8EI044HWS10.A000-1 servo drive is manufactured by B&R Automation and belongs to the 8EI Servo Drives series within the ACOPOS P3 product line. Its role in an automation cell is to convert three-phase mains power into regulated output currents that command a single servo motor while monitoring encoder feedback and application-level shutdown signals. By integrating control, power, and safety functions in one housing, the unit simplifies motion-axis architecture and supports precise torque, velocity, and position regulation. This integrated arrangement also reduces the number of separate control components and interconnecting cables required inside the cabinet.
Configured as a 1-axis module, the drive dedicates its power stage to one motor. It supplies a continuous current of 44 A RMS, supporting sustained operation within the drive’s thermal limits. An input rating of 3 × 200–480 VAC accommodates common industrial supply voltages without requiring a step-down transformer. The unit uses wall mounting, which positions the heat sink against the cabinet panel to promote efficient heat transfer and maintain a compact installation. Feedback wiring connects through a plug-in single resolver interface, allowing the drive to receive motor position information for closed-loop control. Machine-level risk reduction is provided by hardwired STO safety technology, which can prevent torque-producing motor current when the safety circuit is opened. The module is supplied without a front cover and does not contain an internal braking resistor, so braking energy must be handled elsewhere in the drive system when the application requires it.
Field wiring terminates on the Connector Set 1 single-row connection point. A second connector row is not installed, which reduces the space needed for wiring and helps preserve clearance around the module. The standard module option maintains a consistent internal arrangement, cooling path, and cabinet footprint across units of this model. Its fixed connection layout allows power, feedback, and safety wiring to be routed predictably within the enclosure. The single-axis format is suited to applications in which each motor requires a dedicated drive stage and independent control of torque, speed, or position.
