In modern industrial automation systems, servo drives play a critical role in achieving high-speed, high-precision motion control. However, servo systems can also generate electrical noise and electromagnetic interference (EMI), which may affect the performance of sensitive equipment. To ensure stable operation and compliance with EMC requirements, proper filtering components are essential.
The 2198-DBR20-F EMC Filter is a key accessory designed for the Kinetix 2198 Series servo drive platform, providing effective electromagnetic interference suppression and improving the overall reliability of motion control systems.
What Is 2198-DBR20-F?
The 2198-DBR20-F is a 20A three-phase EMC line filter designed for use with Kinetix servo drive systems from Rockwell Automation. It helps reduce conducted emissions generated by servo drives and provides improved electromagnetic compatibility in industrial environments.
Servo drives contain high-frequency switching circuits that control motor speed and torque. During operation, these switching actions can create electrical noise that travels through power lines. Without proper filtering, this interference may impact PLC communication, sensors, encoders and other automation devices.
The 2198-DBR20-F provides an effective solution by filtering unwanted electrical noise while allowing normal power transmission to the servo drive system.

Applications of 2198-DBR20-F in industrial automation
The 2198-DBR20-F is commonly used in applications requiring precise motion control, including:
- Packaging machinery
- Semiconductor manufacturing equipment
- Robotics systems
- Material handling equipment
- CNC machines
- Assembly automation lines
In these applications, servo motors frequently operate with rapid acceleration and deceleration cycles. These dynamic movements require stable power quality and low electrical interference. Installing an EMC filter helps protect system components and improves long-term equipment reliability.
Compatibility with Kinetix Systems
The 2198-DBR20-F is commonly applied with Kinetix servo drive systems, including Kinetix 5500 and related 2198 motion control products. Rockwell Automation recommends appropriate AC line filters to meet EMC requirements and optimize system performance.
When designing a servo system, engineers should select the correct filter according to drive specifications, motor power requirements, cable length and installation environment. Using an unsuitable filter may reduce EMC performance or affect system stability.
Installation considerations
Proper installation is important to achieve maximum EMC performance. The filter should be installed close to the servo drive, with attention to grounding methods and cable routing.
Recommended installation practices include:
- Keep power cables separated from signal and communication cables.
- Use proper grounding techniques to reduce electrical noise.
- Follow Rockwell Automation installation guidelines for wiring and cabinet layout.
- Verify voltage and current ratings before operation.
A well-designed electrical cabinet combined with the correct EMC filtering solution can significantly improve system reliability and reduce troubleshooting time.
