High-power nano servo drives for mobile robotics

Copley Controls has released its Nano High Power (Nano HP) and Nano Plus High Power (Plus-HP) digital servo drives for brush and brushless motors.

Both series expand Copley’s compact Nano family and feature redesigned power boards for higher current output, making them ideal for traction motor applications in autonomous mobile robots (AMR), automated guided vehicles (AGV), and other space-limited mobile robotics requiring higher-power embedded modules.

The Nano HP is based on Copley’s Nano Standard platform with ARM processor, while the Nano Plus-HP is built on the advanced Nano Plus platform with FPGA-based architecture for enhanced functionalities. Both drives operate from 9 to 90 Vdc input voltage and deliver up to 140 A of continuous current, providing exceptional power density and efficiency. They also support EtherCAT (CoE) and CANopen communication protocols for real-time data exchange, with the Plus-HP supporting additional networking protocol options.

Additional features and specifications include:

• Safe Torque Off (STO) capability with SIL 3, Category 3, PL e conformance
• One analog input: ±10 V, 12-bit (HP) / 16-bit (Plus-HP)
• 16-kHz current loop update
• 4-kHz position and velocity loop update
• Five high-speed digital inputs
• Four high-speed digital outputs, including brake
• Multiple encoder interfaces — incremental, absolute, dual feedback and digital halls
• 32-bit floating point filters and multiple advanced filters
• Frequency analysis tools

Nano HP and Plus-HP drives are designed to meet the requirements of many mobile robotics applications, AGVs, AMRs and field robotics. Standard modules can be implemented using connectors or by soldering power pins for high load current applications, while the Z-style modules’ small form factor facilitates integration with standard connectors and a frame-mounted heat plate.
