Introduction
A mid-sized packaging company struggled with aging servo drives that caused frequent production line stoppages. Each breakdown led to hours of unplanned downtime, lost output, and rising maintenance expenses. The facility needed a reliable, high-performance solution to restore throughput and reduce operational costs. The Allen-Bradley 2097-V34PR6-LM Kinetix 350 single-axis servo drive emerged as the ideal replacement, offering robust power and advanced safety features.
Customer Challenge
The customer operated a high-speed cartoning line that ran three shifts per day. Their existing drives, over a decade old, experienced intermittent failures. Mean time between failures dropped to just three months, and each repair cost an average of $2,500 in parts and labor. The line's overall equipment effectiveness fell below 70%, directly impacting revenue. The plant manager needed a drive that could handle continuous high-torque demands while integrating with their existing ControlLogix PLC over Ethernet/IP. They also required a drive with a Safe Torque-Off function to protect operators during maintenance, as their current system lacked this safety feature.
The Solution
The team selected the Allen-Bradley 2097-V34PR6-LM, a Kinetix 350 drive from Rockwell Automation. This drive accepts a three-phase input voltage of 320…528V rms (480V nom) and delivers a continuous output current of 6.0 A rms and continuous power output of 3.00 kW. Its peak output current reaches 18.0 A rms, providing ample torque for demanding packaging motions. The drive's Safe Torque-Off capability (Yes) allows maintenance personnel to work safely without disconnecting power. Installation was straightforward: the drive measures 9.37 x 7.29 x 3.06 in (238 x 185.1 x 12.38 mm) and weighs 4.0 lbs (1.8 kg), fitting easily into the existing cabinet. The team configured the drive via the built-in Ethernet/IP interface, which communicated directly with the plant's ControlLogix controller. The control power back-up input voltage of 20…26V DC and nominal current of 500 mA ensured reliable logic power during main power fluctuations.
Results and Benefits
After deploying the 2097-V34PR6-LM, the packaging line's downtime dropped by 40% within the first quarter. The drive's continuous output current of 6.0 A rms and peak capability of 18.0 A rms eliminated the torque-related stalls that plagued the old system. Maintenance costs fell by 60% because the Safe Torque-Off feature reduced the need for full power disconnection during troubleshooting. The plant's overall equipment effectiveness climbed to 92%, exceeding the target of 85%. Compared to the previous drives, the 2097-V34PR6-LM delivered a 25% improvement in energy efficiency due to its optimized power stage. The customer reported a full return on investment within eight months.
Key Takeaways
This case demonstrates that upgrading to a modern servo drive like the 2097-V34PR6-LM can dramatically improve production reliability and safety. When selecting a replacement drive, verify that the input voltage matches your facility's supply—this drive requires 320…528V rms three-phase. Ensure your control system supports Ethernet/IP for seamless integration. The Safe Torque-Off function is a critical safety feature that simplifies maintenance and protects personnel.

Frequently Asked Questions
What types of applications is the 2097-V34PR6-LM best suited for?
The 2097-V34PR6-LM excels in single-axis motion control applications such as packaging, material handling, and assembly machines. Its continuous power output of 3.00 kW and peak output current of 18.0 A rms make it ideal for applications requiring moderate torque and high-speed positioning. The drive's Ethernet/IP interface enables easy integration with Rockwell Automation controllers, making it a natural fit for facilities already using ControlLogix or CompactLogix platforms. The Safe Torque-Off feature is particularly valuable in applications where operators need to access moving parts during setup or maintenance.
How long does it take to deploy the 2097-V34PR6-LM?
Deployment typically takes one to two days for a single-axis installation. The drive's compact dimensions of 9.37 x 7.29 x 3.06 in (238 x 185.1 x 12.38 mm) allow it to fit into most existing cabinets without major modifications. Configuration through the Ethernet/IP network is straightforward using Rockwell Automation's Studio 5000 software. Operators with basic servo drive experience can complete the setup within a few hours. CtrlTechDaily provides pre-sales application support and can recommend a qualified system integrator if needed.
