Energy return
During deceleration, motor energy returns to the drive DC link instead of disappearing through the motor-output conductors.

Product Description
Allen-Bradley 2198-E4055-ERS / 2198-E4075-ERS are Kinetix 5100 servo drives for higher-output axes in the family’s high-voltage class. Each drive forms the controlled link between an EtherNet/IP motion controller and the motor assigned to that machine axis.
Allen-Bradley 2198-E4055-ERS / 2198-E4075-ERS occupy adjacent roles in the Kinetix 5100 range, but each must remain paired with its selected motor and cabinet design. The catalog number anchors the controller entry, braking arrangement and feedback cable set, preventing a higher-output axis from being commissioned with the neighboring drive configuration.

Regenerative Energy Management
The braking circuit handles energy returned by the motor during deceleration and must be completed before high-inertia motion is commissioned.
External shunt route
Connect the specified passive shunt through the drive shunt path so returned energy has a controlled dissipation route.
Commissioning check
Verify the shunt wiring and resistor selection before running a deceleration profile that can regenerate energy.
Primary and Auxiliary Feedback
The primary motor loop and optional auxiliary measurement enter through different connectors and serve different control functions.
Primary loop
Terminate the motor feedback cable at MFB so the servo loop receives the motor position used for commutation and control.
Auxiliary measurement
Use AUX only for a supported secondary feedback signal; do not move the primary motor-feedback cable to this connector.
Signal ownership
Keep both feedback assignments associated with the same axis entry while EtherNet/IP carries commands and status separately.
Frequently Asked Questions
How should 2198-E4055-ERS / 2198-E4075-ERS be distinguished on a motor axis?
Use the rated output and current values, not only the common 400 V-class family name. E4055 is 5.5 kW with 24.80 A continuous output, while E4075 is 7.5 kW with 31.0 A continuous output.
Does 2198-E4055-ERS / 2198-E4075-ERS use an internal braking resistor?
These two drive sizes use an external passive-shunt arrangement. Include the required shunt path when the application needs regenerative energy handling; do not wire them as an internal-shunt drive.
Where do motor and auxiliary feedback connect on 2198-E4055-ERS / 2198-E4075-ERS?
The motor feedback connection is the 15-pin MFB connector, while the auxiliary feedback connection is the separate 10-pin AUX connector. Keep the two feedback functions separate during cable preparation and controller configuration.
What supply inputs must be planned for 2198-E4055-ERS / 2198-E4075-ERS?
Provide the 342...528 V rms three-phase AC input and the 24 V DC control-power input. The control supply is separate from the three-phase power that feeds the motor-output stage.
How can 2198-E4055-ERS / 2198-E4075-ERS be connected to EtherNet/IP?
Each drive has two 10/100 Mbps RJ45 EtherNet/IP ports and supports linear, ring and star topologies. Use that network path for controller communication; it is not a substitute for the motor feedback or U/V/W connections.
Why does cabinet space matter for 2198-E4055-ERS / 2198-E4075-ERS?
Both drives have a 300 mm minimum recommended cabinet depth, and their full-load power loss differs by model. Confirm the physical depth and thermal load against the selected E4055 or E4075 rating before finalizing the enclosure.
