8EI4X5HWD10.0600-1 by B & R Automation

The 8EI4X5HWD10.0600-1 is a servo drive module manufactured by B & R Automation for the 8EI Servo Drives series. Within the ACOPOS P3 8EI servo drive product series, it serves as a compact power stage that regulates current for multiple motors in automated machinery. By combining power electronics, feedback processing, and safety circuitry in one housing, the unit supports coordinated speed, torque, and position control on conveyors, gantries, and tooling axes used in industrial automation. It is intended for machinery that requires synchronized motion across multiple axes during continuous production.

The module is classified as a 2-axis module, so two independent motor channels share a common DC bus inside the housing. It accepts a three-phase input of 3x 200-480 VAC, allowing direct connection to standard plant mains without an autotransformer. Each axis can deliver a continuous output of 4.5 Aeff, which is the steady-state RMS current the drive can supply without derating. An integrated internal braking resistor converts regenerated energy to heat during rapid deceleration, reducing the need for an external resistor on moderate-inertia loads. That arrangement helps absorb returned energy during braking events instead of feeding it back into the supply path. For personnel protection, the drive provides hardwired STO safety technology with encoder monitoring, so torque-producing power is cut when the safety loop opens. The device is supplied in the standard module option.

For cabinet wiring, this variant is supplied with Connector Set 1, a single-row terminal block that carries power, brake, and sensor lines. The single-row layout keeps the main connections grouped in one accessible interface. A front cover shields the terminals from debris during installation and operation. The unit is intended for wall mounting on a grounded backplate so airflow can pass along the heat sink. The two-row connector arrangement is omitted on this version, which helps reduce the installation depth required in the enclosure.
