Application Areas and Application Cases

The Allen-Bradley 1397-B300N is widely used in various industrial applications requiring precise single-axis motion control:

Packaging Machinery: Control of conveyors, feeders, cut-to-length systems, and other single-axis movements in packaging lines.
Material Handling: Driving individual conveyors, sorting gates, or small robotic grippers in material handling systems.
Assembly Machines: Precise positioning of components in automated assembly cells, pick-and-place applications.
Printing and Converting: Control of individual rollers or cutting blades in printing presses, labeling machines, or converting equipment.
Small Machine Tools: Driving axes for grinding, drilling, or milling machines where a single axis requires precise motion.

Application Case: In a pharmaceutical packaging line, a 1397-B300N servo drive was used to precisely control the indexing conveyor that positions bottles under a filling nozzle. The drive received position commands from a central PLC. The Ultra 3000 drive’s ability to precisely control the motor’s acceleration, deceleration, and stop position ensured that each bottle was accurately placed for filling, minimizing spillage and maximizing throughput. Its compact size allowed it to be mounted directly within the machine’s control panel, saving valuable space. The built-in diagnostics helped technicians quickly identify and resolve any motor or feedback issues, reducing downtime.

Competitive Comparison

The Allen-Bradley 1397-B300N competes in the single-axis servo drive market against offerings from manufacturers like Siemens (e.g., SINAMICS V series), Bosch Rexroth (e.g., IndraDrive Cs), Yaskawa (Sigma series), and Schneider Electric (e.g., Lexium 32 series). Key competitive differentiators include:

Integration with Rockwell Ecosystem: A primary advantage of the Allen-Bradley 1397-B300N is its deep integration with Allen-Bradley PLCs and Rockwell Software. This streamlines programming, configuration, and troubleshooting for users standardized on Rockwell platforms.
Compactness and Cost-Effectiveness: The Ultra 3000 series is designed to be a cost-effective solution for single-axis applications while maintaining Allen-Bradley’s reputation for quality and reliability. Competitors also offer compact drives, but the overall system cost and ease of integration can vary.
Performance vs. Complexity: While other high-end servo drives may offer more advanced features or higher dynamic performance for extremely complex multi-axis synchronization, the Allen-Bradley 1397-B300N provides excellent performance for single-axis applications without the added complexity or cost, hitting a sweet spot for many machine builders.
Ease of Use: Tools like UltraWare simplify setup and tuning, making it accessible even for users without extensive motion control experience.

Selection Advice

When selecting the Allen-Bradley 1397-B300N or a similar single-axis servo drive, consider the following:

Motor Compatibility: Ensure the drive is compatible with your chosen servo motor (e.g., Allen-Bradley Kinetix motors are recommended for optimal performance). Verify the motor’s continuous and peak current requirements match the drive’s output capabilities.
Voltage Requirements: Confirm the drive’s input voltage rating (e.g., 230V AC or 460V AC class) matches your available facility power. The “B” prefix in 1397-B300N is critical for this.
Feedback Type: Ensure the drive supports the feedback device (resolver, incremental encoder, absolute encoder) on your chosen motor.
Control Interface: Verify that your control system (PLC, dedicated motion controller) can provide the necessary control signals (e.g., digital I/O for step/direction, analog for velocity/torque, or serial commands).
Regenerative Braking Needs: If your application involves high inertia or frequent deceleration, assess if the internal shunt resistor is sufficient, or if an external shunt resistor will be required.
Application Complexity: For simple to moderately complex single-axis motion, the 1397-B300N is an excellent choice. For highly complex multi-axis coordinated motion, a more advanced motion control system (e.g., Kinetix 5700) might be more appropriate.

Precautions

When installing and operating the Allen-Bradley 1397-B300N, observe the following critical precautions:

Power Disconnection and Lockout/Tagout: Always ensure all power sources to the drive (input power, control power) are completely disconnected, locked out, and verified as de-energized with a voltmeter before performing any installation, wiring, or maintenance. Servo drives contain high-voltage capacitors that can store dangerous energy even after power removal.
Electrostatic Discharge (ESD) Protection: The drive contains sensitive electronic components. Use proper ESD control procedures (e.g., wearing an ESD wrist strap, working on a grounded static-dissipative mat) when handling the module to prevent damage.
Proper Grounding and Wiring: Adhere strictly to all local and national electrical codes, as well as Allen-Bradley’s specific wiring diagrams and guidelines for input power, motor connections, feedback devices, and control signals. Improper grounding or wiring can lead to electrical hazards, equipment damage, or unreliable operation.
Thermal Management: Install the drive in an environment that maintains the specified operating temperature and humidity ranges. Ensure adequate ventilation and airflow around the drive within the enclosure to prevent overheating, which can lead to reduced performance and premature failure.
Firmware and Software Compatibility: Verify that the firmware version on the Allen-Bradley 1397-B300N is compatible with the version of the programming and configuration software (e.g., UltraWare) and your chosen controller. Incompatibility can cause unexpected behavior or prevent proper configuration.
Qualified Personnel: Only qualified and trained personnel who are thoroughly familiar with solid-state control equipment, servo systems, and relevant safety standards (e.g., NFPA 70E) should install, program, troubleshoot, or service this drive.
