DC servo-drive

EtherCATfor robots24 V

Overview
This low-voltage hollow joint driver is designed for direct integration into robot joints with centralised wiring. The daisy-chain architecture carries EtherCAT, logic power and safety signals, while model‑predictive vector control maintains system efficiency at or above 98%.

Key features

• Modular structure: Standardised interfaces enable rapid deployment, straightforward maintenance, flexibility and scalability.
• Safety functions: On-board STO (Safe Torque Off) and SBC (Safety Brake Control) accessible via 24V I/O.
• Ultra-high efficiency: Model‑predictive vector control delivers high-frequency motion control with low thermal dissipation (efficiency ≥98%).
• Simplified wiring: Daisy‑chain topology consolidates EtherCAT, logic power and safety signals to reduce cabling complexity in joints.
• Compact joint integration: Designed for hollow-cavity, low-voltage articulations to minimise volume and simplify assembly.

Applications

• Integration into industrial robot joints and articulated arms for assembly, machine tending, welding and material handling.
• Collaborative robot joints where compact form factor and embedded safety are required.
• Robotic systems requiring chained EtherCAT communication and centralised power/safety wiring.
