8EI034HWS10.0300-1 by B & R Automation

The 8EI034HWS10.0300-1 is a servo drive from the 8EI Servo Drives series produced by B & R Automation. It belongs to the ACOPOS P3 8EI product line and supplies controlled power to synchronous or induction servo motors in automated machinery. By regulating current to the motor, it supports precise torque and velocity control in packaging systems, transfer axes, and material-handling equipment. This operating role makes it suitable for motion applications that require repeatable response during changing load conditions.

The unit is delivered as a 1-axis module, so it supports one motor channel. It provides a continuous output of 34 Aeff, which suits medium-power axes that run under steady load. The drive accepts a three-phase mains input of 3x 200-480 VAC, covering a broad range of industrial supply voltages. Functional safety is handled through hardwired STO safety technology with encoder, which removes torque during a fault while maintaining the encoder path used for monitored motion functions. Field wiring is completed through Connector Set 2 (2-row), and any communication expansion must be provided outside the drive because no plug-in option card is included.

Installation uses wall mounting tabs that fit standard cabinet layouts, and a molded front cover protects the bus capacitors and terminal area from incidental contact while remaining removable for access. The enclosure arrangement keeps the power section and connection points organized inside the cabinet, which helps maintain clear routing around adjacent components. The drive has no internal braking resistor, so regenerated energy must be routed to an external braking resistor during deceleration. The configuration follows the standard module option, which indicates a standard build without extra plug-in modules or user-specific modifications.
