Product Description:

The 8EI4X5HWT10.0500-1 servo drive module, produced by B&R Automation and supplied within the 8EI Servo Drives series, is intended to control multiple AC servo axes in machine automation. It belongs to the ACOPOS P3 8EI servo drive product line and integrates power electronics, control logic, and motion-feedback handling for synchronized positioning tasks. By coordinating several motors from a compact enclosure, the unit simplifies cabinet layouts and supports short loop times in packaging machines, material-handling stages, and other high-precision applications. It is identified in ordering documents under this exact part number. The integrated layout also reduces the number of separate modules required for multi-axis control in a single cabinet.

The module accepts a three-phase supply rated at 3x 200-480 VAC, giving it flexibility to operate on global mains systems without an external transformer. Each axis can deliver a continuous drive current of 4.5 Aeff, providing sustained output to connected servomotors during steady-state motion. The hardware is configured as a 3-axis module, so three independent current inverters share a common DC link and cooling path inside one housing. This arrangement places multiple servo channels in one enclosure while using the same incoming power section. The same product family is also offered as a 1-axis module for applications that require fewer controlled axes.

System integration is supported by hardwired STO safety technology with encoder, which permits direct shutdown of torque on all channels without additional relays. Dynamic deceleration energy is handled by a built-in internal braking resistor, reducing the need for an external dump resistor on medium-inertia loads. The housing is intended for wall mounting, which positions the heat sink against a metal plate for guided convection. Field wiring uses Connector Set 2 (2-row), giving separate keyed rows for power and feedback leads. The keyed connector rows help keep power and feedback connections separated, and the unit is supplied with no plug-in module.
