Product Overview
The Allen Bradley 2198-K57CK-D15M Kinetix 5700 Feedback Connector Kit is a universal feedback connection accessory for Kinetix 5700 servo drive systems. It provides the termination arrangement needed to connect compatible encoder signals carried by Allen-Bradley 2090-Series feedback cables to the drive’s 15-pin Universal Feedback (UFB) connector.
In a servo-controlled machine, the drive depends on feedback from an encoder to determine motor position and support accurate motion control. The encoder may use absolute, incremental, or EnDat feedback technology, depending on the motor and application. The 2198-K57CK-D15M provides the electrical connection between the prepared feedback cable conductors and the drive interface, allowing supported feedback signals to reach the control electronics.
This kit is particularly useful in multi-axis machinery where several motors require individual feedback connections. Packaging equipment, automated assembly lines, and material-handling systems often use servo axes with different motion profiles. Each feedback cable must be terminated correctly so that the drive receives the intended encoder signals without intermittent connections or electrical interference.
The connector kit accommodates the wiring of feedback conductors to an internal terminal block and provides a defined arrangement for cable-shield termination. The cable must be prepared carefully before installation. Conductor lengths need to allow a suitable service loop, insulation must be stripped to the required length, and the shield drain wire must be connected to the designated terminal. These details affect both connection quality and the feedback circuit’s resistance to electrical noise.
The 2198-K57CK-D15M is also relevant when a compatible Kinetix 5700 drive uses the universal feedback interface for an auxiliary feedback device. In this arrangement, the encoder can provide information for a supported load-position or secondary feedback application, subject to the drive configuration. This differs from the primary motor-feedback arrangement, where the feedback device is used directly for motor control.
The kit does not convert one encoder protocol into another. Compatible feedback signals pass through the connector assembly to the drive. Consequently, the selected encoder, cable, terminal assignments, and drive configuration must match the intended application. A connector that fits mechanically does not make an otherwise unsupported feedback device compatible.
For commissioning engineers, the main considerations are cable preparation, pin assignment, shield termination, and connector engagement. If the drive reports a feedback fault, checking these items alongside encoder compatibility and drive configuration is a practical starting point. Correct termination helps the drive receive usable feedback and reduces avoidable commissioning problems.

Working Principle
The 2198-K57CK-D15M establishes an electrical path between a compatible encoder cable and the Kinetix 5700 drive’s Universal Feedback connector. The kit does not interpret position data or calculate motor movement. Those tasks remain with the encoder and drive control electronics.
Encoder → 2090-Series Feedback Cable → 2198-K57CK-D15M → UFB Connector → Kinetix 5700 Drive
The encoder generates feedback signals according to its technology. An absolute encoder supplies position information within its supported measurement range, while an incremental encoder generates signals from which the drive can determine movement. EnDat devices use their corresponding feedback interface. The drive must be configured for a feedback type that it supports.
During installation, the feedback cable is prepared so that its conductors reach the correct terminals without excessive tension. The individual wires are inserted into their assigned positions and secured. The exposed cable shield is positioned under the designated clamp, and the drain wire is connected to pin 16 as specified for this kit. The completed assembly then connects to the drive’s UFB interface.
Consider a machine with a servo motor driving a positioning table. As the motor rotates, the encoder generates feedback that the drive uses to regulate movement. The connector kit carries the encoder signals to the drive, allowing the control system to compare the measured feedback with the commanded motion. The drive then adjusts motor output to follow the requested position or velocity profile.
The same connection principle can apply to a supported auxiliary feedback arrangement. For example, a machine may need to monitor load position separately from motor position. If the selected Kinetix 5700 configuration supports the required auxiliary feedback device, the connector kit can provide the necessary termination path for that encoder.
Signal integrity depends on correct assembly. A conductor placed in the wrong terminal can prevent the drive from interpreting the encoder signals correctly. A loose wire may cause intermittent feedback loss, while improper shield termination can increase susceptibility to electrical interference. The cable should also be routed to avoid unnecessary strain and interference from high-power wiring.
Because the kit is a passive connection accessory, it cannot make an incompatible encoder suitable for the drive. The feedback device and its electrical interface must be supported by the drive, and the wiring must follow the correct pin assignment for that device.

The 2198-K57CK-D15M provides the termination interface between a compatible feedback cable and the Kinetix 5700 drive. Its role is to maintain the intended signal connections so the drive can receive motor-position or supported auxiliary feedback.

Installation and Maintenance
- Confirm feedback compatibility: Check that the encoder type, feedback cable, and Kinetix 5700 drive support the intended motor or auxiliary feedback arrangement.
- Inspect the connector kit: Examine the connector body, terminal block, shield clamp, and mounting features for damage before installation.
- Prepare the feedback cable: Follow the applicable cable-preparation instructions for jacket removal, shield exposure, conductor length, and insulation stripping.
- Trim the shield carefully: Prevent loose shield strands from contacting adjacent terminals or creating an unintended electrical connection.
- Prepare the drain wire: Ensure the drain wire is available for connection to pin 16. If the cable does not include a separate drain wire, follow the specified procedure for forming one from the overall shield braid.
- Identify the terminal assignments: Use the correct pinout for the encoder and drive configuration instead of relying only on conductor colors.
- Route the conductors: Insert each wire into its assigned terminal and leave sufficient service-loop length for the longest conductors.
- Tighten the terminal screws: Apply the specified terminal torque and check that each conductor is securely retained.
- Secure the cable shield: Position the exposed shield in the designated channel and tighten the shield-clamp screws to the specified torque.
- Provide strain relief: Arrange the cable and service loop so that movement, vibration, or cable tension does not pull on the terminal connections.
- Connect and test the feedback path: Mount the connector kit, engage the UFB connector correctly, and verify that the drive recognizes the configured feedback device during commissioning.
- Document inspection results: Record the encoder type, cable identification, terminal arrangement, and any feedback faults observed during testing.
When a feedback fault occurs, inspect the terminal wiring, shield connection, connector seating, and cable condition before replacing the kit. Also confirm that the drive is configured for the installed encoder type.

Technical FAQs
How does the 2198-K57CK-D15M differ from the 2198-H2DCK?
The 2198-K57CK-D15M is a universal feedback connector kit through which compatible encoder signals pass to the drive. The 2198-H2DCK performs a specific conversion from 15-pin Hiperface feedback to the two-pin DSL interface. They serve different feedback connection arrangements and are not interchangeable in every installation.
Which feedback technologies can be used with the 2198-K57CK-D15M?
The Kinetix 5700 UFB interface supports compatible single-turn and multi-turn absolute feedback, incremental feedback, and EnDat feedback technologies. The exact encoder type and electrical interface must be supported by the selected drive and its configuration.
Why must the feedback cable drain wire connect to pin 16?
The drain-wire connection establishes the specified shield termination for the feedback cable. Correct shield bonding helps control electrical interference in a servo installation. If the cable does not contain a separate drain wire, the installation instructions specify how to form one from the overall shield braid.
Can this connector kit be used for auxiliary feedback instead of motor feedback?
Yes, where the selected Kinetix 5700 drive and feedback configuration support auxiliary feedback. The kit provides the physical termination interface, but the encoder type, signal assignment, and drive setup must all be appropriate for the intended auxiliary-feedback function.
