8EI2X2HWS10.0500-1 by B & R Automation

B&R Automation manufactures the 8EI2X2HWS10.0500-1 servo drive as part of the ACOPOS P3 8EI servo drive series. This unit conditions three-phase mains power, regulates motor current, and processes encoder feedback so industrial axes can reach commanded positions with consistent torque and velocity during dynamic load changes. It is intended for packaging lines, assembly stations, and conveyor zones, where it serves as the power stage of a distributed motion system and works with neighboring modules over the system bus to support coordinated multi-axis motion.

Electrically, the drive accepts an input range of 3x 200-480 VAC and supplies a continuous motor current of 2.2 Aeff. Safe torque removal is built in through hardwired STO safety with encoder, allowing the axis to enter a no-torque state without disabling controller logic. An internal braking resistor dissipates regenerated energy during deceleration, which reduces the need for an external brake chopper in many applications. The front panel uses a 2-row connector set, which provides the required cable connection layout. The device ships without a front cover, leaving the connection area directly accessible inside the cabinet.

Mechanically, installation is by wall mounting inside a control cabinet, and the housing uses the series cooling path that transfers heat through the panel. The delivered configuration is a 1-axis module with the standard module option, indicating that no extra performance add-ons are included. The shipment reflects the lack of a plug-in module, so any added fieldbus or feedback expansion must be handled through external expansion cards. This arrangement keeps the delivered hardware focused on the base power stage while leaving interface expansion outside the main housing for applications that require additional interface functions.
