8EI034HWS10.A000-1
The 8EI034HWS10.A000-1 servo drive is a power module produced by B & R Automation within the 8EI Servo Drives series. Built for the ACOPOS P3 platform, it conditions three-phase supply power and modulates motor current for precise motion control in machine tools, packaging lines, and material-handling equipment. Its continuous output current reaches 34 Aeff, which allows the unit to operate medium-sized servomotors through sustained duty cycles without immediate thermal reduction. This operating profile makes the module suitable for installations that require consistent axis response during repeated acceleration and holding periods.
The drive accepts an input range of 3x 200–480 VAC, so it can operate from common industrial supply systems without a transformer tap change. It is built as a 1-axis module, which means each unit is assigned to a single motor channel in the control cabinet. Mechanical installation uses wall mounting, allowing the module to be secured directly to the cabinet structure for stable placement and short power connections. Integrated safety is provided by hardwired STO safety with encoder, which removes torque-producing energy during a stop command while keeping feedback available for monitored motion functions. Motor feedback is connected through a Resolver 1x interface, making the unit compatible with resolver-based position sensing on supported servo motors.
Power and signal wiring use Connector Set 1 (1-row), which keeps the interface layout straightforward at the front of the module. A front cover is not supplied, so protective access must be provided by the machine enclosure or panel door. The drive has no internal braking resistor, so regenerated energy from deceleration must be handled by an external braking solution or by a shared DC bus arrangement. The module is supplied without a special factory option, which keeps the configuration aligned with the standard version used for this model line.
