Servodrives for brush and brushless motors in mobile robotics
Nano High Power (Nano HP) and Nano Plus High Power (Plus-HP) digital servodrives for brush and brushless motors 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.
Nano HP is based on Copley´s Nano Standard platform with ARM processor, while Nano Plus-HP is built on the Nano Plus platform with FPGA-based architecture for enhanced functions. Both servodrives operate with 9-90 VDC input voltage and deliver up to 140 A of continuous current. They also support EtherCAT (CoE) and CANopen communication protocols for real-time data exchange, with Plus-HP supporting additional networking protocol options.
Other features and specifications include:
- Safe torque off (STO) with SIL 3, Category 3, PL e conformance.
- One analog input at ±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, including incremental, absolute, dual feedback and digital halls.
- 32-bit, floating-point filters and multiple advanced filters.
- Frequency analysis tools.
· Nano HP and Plus-HP’s standard modules can be implemented using connectors, or by soldering power pins for high load current applications, while Z-style modules’ small form factor aids integration with standard connectors and a frame-mounted heat plate.
