Compared to basic servo drives, it offers significantly more advanced control features and programmability. The specific variant code “JA1” is crucial as it defines the exact communication protocol and power rating.

Selection Suggestions and Precautions

• Selection Advice: Select the EMERSON KJ2201X1-JA1 for applications requiring high-performance servo control with flexible networking. It is well-suited for OEM machine builders and system integrators. The selection must be based on matching the drive’s current and voltage rating to the servo motor’s requirements and choosing the correct communication variant (“JA1”) for the host controller’s network.
• Precautions:
  1. Motor-Drive Compatibility: Ensure the drive is fully compatible with the specific servo motor (voltage, current, feedback type). Using an incompatible motor can lead to poor performance or damage.
  2. Regenerative Energy Management: For applications with frequent deceleration or overhauling loads, ensure the system design includes a properly sized braking resistor to dissipate regenerative energy.
  3. EMC Installation: Follow strict EMC installation guidelines: use shielded motor cables, proper grounding, and install line filters as recommended to prevent electrical noise issues.
  4. Commissioning & Tuning: Proper commissioning using WorkBench is critical. Auto-tuning provides a good start, but complex mechanics often require manual fine-tuning of the control loops (gains, filters) for optimal performance.
  5. Firmware & Configuration Backup: Always back up the drive’s configuration and parameters. Ensure the firmware version is compatible with the WorkBench software and other networked drives.
