Product Description:

The 8EI4X5HWDS0.0700-1 servo drive is manufactured by B&R Automation as part of the 8EI Servo Drives series in the ACOPOS P3 8EI product line. It conditions incoming line power, monitors feedback, and issues PWM voltage to attached motors, enabling tight velocity and torque control in packaging, assembly, and robotics work cells where synchronized motion and embedded functional safety are required. Its compact form factor reduces panel depth and simplifies cable routing in distributed automation architectures. Because feedback processing and power conversion are handled in the same device, the drive can respond quickly to commanded speed and torque changes during coordinated motion. Placing the drive close to the machine section it serves can also shorten motor and feedback cable runs.

The drive has a continuous RMS phase current of 4.5 Aeff, and it operates from a supply range of 3x 200-480 VAC. The unit is configured as a 2-axis module, so one housing shares the DC link and control electronics for two motor channels; this arrangement saves cabinet width while keeping both axes in a compact package. Heat generated during rapid deceleration is absorbed by an integrated internal braking resistor, reducing the need for external braking hardware. For installation, the chassis supports wall mounting, allowing direct attachment to a steel backplane and leaving a clear path for cooling air around the heat sink. The shared housing also concentrates power and control connections in one location, which helps keep cabinet layouts organized on multi-axis machines.

The built-in safety package is SafeMOTION, which uses a digital encoder interface to monitor velocity and position for STO, SS1, and other motion-safe states. For wiring, the design omits Connector Set 1 but includes Connector Set 2 (2-row), so power conductors and signal pins remain separated on a single header. This separation helps keep control wiring orderly and reduces interaction between low-level signals and motor power connections. The platform can also be supplied as a 1-axis module or a 3-axis module when a machine requires a different number of channels. Using the same platform across different channel counts keeps the interface style consistent when a machine layout requires more or fewer axes. The unit ships with a front cover, the standard module option, no customization, and no plug-in module, leaving the base hardware in a straightforward standard configuration.
