Compact and robust digital servo drives are gaining importance in the robotics industry, particularly for autonomous mobile robots and space-limited applications. Copley Controls has introduced its Nano High Power (Nano HP) and Nano Plus High Power (Plus-HP) digital servo drives, responding to this need for higher current output in a smaller package. These drives target designers working on AGVs, AMRs, and other mobile robotics that operate in tight spaces but demand significant power delivery. Experts have noted that as robotics platforms diversify and become more accessible, embedded power solutions like these are expected to see increased adoption. The arrival of Nano HP and Plus-HP continues a trend toward specialized, high-efficiency servo drives that integrate advanced safety and communication features.
Earlier product launches by Copley Controls in the Nano series emphasized compact size and flexibility but did not offer as high a current output or advanced safety certifications as seen in the new drives. Competing solutions from other brands tended to prioritize either size or performance; the newly released Nano HP and Plus-HP aim to combine both characteristics for a broader range of applications. Industry commentary has also pointed out the growing integration of communication protocols such as EtherCAT and CANopen in similar products, which aligns with current market expectations that the Nano HP and Plus-HP fulfill.
What Sets Nano HP and Plus-HP Apart?
The Nano HP is built on Copley’s Nano Standard platform incorporating an ARM processor, while the Nano Plus-HP uses an FPGA-based architecture for additional functionalities. Both models operate across a 9 to 90 Vdc input range and deliver up to 140 A continuous current, offering high power density tailored for traction motors in mobile robotics. The inclusion of EtherCAT (CoE) and CANopen communication supports real-time data exchange, with the Plus-HP offering a wider selection of networking options for diverse integration requirements.
What Features Address Safety and Integration Demands?
Both servo drives offer Safe Torque Off (STO) capability that meets the rigorous SIL 3, Category 3, PL e safety standards. They include one analog input—with the Plus-HP reaching 16-bit resolution—a 16-kHz current loop update rate, and 4-kHz position/velocity loop updates for fine-tuned control. Additionally, multiple encoder interface options, high-speed digital I/O, floating point filters, and frequency analysis tools expand the range of suitable automation tasks.
How Do These Drives Support Flexible Robotics Design?
Copley Controls has designed the modules to accommodate various installation methods, allowing for connection via standard connectors or direct soldering of power pins for heavy-load uses. The Z-style module, with its compact frame and integrated heat plate, enables easy mounting within tight robotic platforms. According to Copley Controls, these features make the Nano HP and Plus-HP well-suited for developers who require adaptability and efficiency in their embedded servo drives.
“Our new Nano HP and Plus-HP drives aim to address the unique power and integration needs of mobile robotics, AGVs, and AMRs,” a representative from Copley Controls stated.
Manufacturers and automation engineers can also benefit from the drives’ compliance with stringent safety protocols and their compatibility with both brush and brushless motors. Suitability for AGVs and AMRs has been underscored by product specifications supporting traction motor requirements, while enhanced networking options favor system-level communication in complex robotic environments.
“The small footprint of our Z-style modules enables straightforward integration even in space-constrained environments,” added the Copley Controls spokesperson.
With the introduction of the Nano HP and Plus-HP digital servo drives, Copley Controls has expanded its line-up in a market where high output and compact design are essential for robotic mobility and flexibility. Both drives incorporate industry-standard safety features and support modern communication protocols recognized in advanced robotics systems. As robotics manufacturers push for ever-more integration and higher performance from embedded hardware, products like Nano HP and Plus-HP give developers added flexibility for a wide variety of mobile robotic platforms. The balance between power output, communication compatibility, and compact form factor stands out as a response to current industry requirements. For those in the field of robotics, especially in transportation and logistics automation, these drives offer a solution that can align with evolving project and operational needs.
