8EI017HWS10.0200-1 by B & R Automation

The 8EI017HWS10.0200-1 is a servo drive from B & R Automation in the 8EI Servo Drives series. It serves as the regulated power interface between a three-phase mains supply and a synchronous motor, delivering controlled current so industrial axes can follow commanded speed and torque profiles. This arrangement supports accurate acceleration, stable speed regulation, and repeatable response in automated motion systems. Because current delivery is synchronized with motor feedback, the drive can support smooth motion during positioning, indexing, and speed-controlled tasks. The module combines power conversion and axis control functions in one housing, which reduces the number of separate components needed inside the cabinet.

As delivered, the drive is configured as a 1-axis module. Its power stage can supply a continuous motor current of 17 Aeff while operating from an input of 3x 200-480 VAC, covering a wide range of industrial supply conditions. The housing is intended for wall mounting, which keeps the cooling surfaces exposed to cabinet airflow and supports a direct installation layout. For personnel protection, the control section includes hardwired STO channels that remove torque when the safety circuit is opened, while encoder feedback supports controlled motor operation during normal running. The integrated layout keeps the axis interface and control functions close to the power electronics, so the enclosure remains compact.

Signal and power leads attach through a 1-row connector set, which keeps the connection layout compact and easy to route in a cabinet. The drive has no internal braking resistor, so regenerative energy must be directed to an external resistor or a common DC bus during deceleration. The axis interface, velocity observer, and parameter memory are housed in the same enclosure, which keeps related control functions together and avoids extra interface modules. A factory-installed front cover shields live conductors and closes off the connection area during operation. This layout helps maintain a clean front profile without adding separate protective parts at the point of use.
