OMRON has introduced its new C6 Series AC servo system, designed for light-duty tasks in the modern automation world. This series covers a wide power range from 50 W to 7.5 kW and is offered in both 230 V single-phase and 400 V three-phase configurations.
⚙️ Hardware and Mechanical Design
C6 servo drives feature a compact design with the same height for models up to 3 kW. This simplifies control panel layout, shortens mounting time, and reduces installation costs. Thanks to pluggable connectors, wiring and replacement processes are very easy.
đź”’ Control and Safety Features
The system provides feedback with an integrated 26-bit motor encoder that can be configured for incremental or battery-backed absolute positioning. Offering a 3.5 kHz velocity loop frequency response, this drive supports full closed-loop operation with an external secondary encoder. For safety, an integrated Safe Torque Off (STO) function, meeting ISO 13849-1 Category 4, PLe and IEC 61508 / IEC 62061 SIL 3 criteria, is standard.
đź’» Software Integration and Positioning
In the OMRON product range, the C6 Series stands out as a cost-effective solution for light-duty tasks, while the existing 1S Series is positioned for high-performance and heavy-duty applications up to 15 kW. Configuration, commissioning, and system maintenance are managed via the Sysmac Studio integrated development platform, along with NX series machine automation controllers, distributed I/O, sensing, machine vision, and safety hardware, all over the high-speed EtherCAT real-time fieldbus.
🔍 Technical Details
Modern AC servo architectures combine high-bandwidth current and velocity control loops with high-resolution feedback to improve low-speed ripple and micro-positioning accuracy. The 26-bit absolute encoder provides 67,108,864 counts per revolution, offering a significant improvement over traditional options. The 3.5 kHz velocity loop frequency response allows the drive to react quickly to dynamic load fluctuations. In dual-loop or full closed-loop modes, direct feedback from linear scales or secondary rotary encoders eliminates the effects of mechanical backlash, thermal expansion, and drivetrain compliance. Network synchronization via EtherCAT Distributed Clocks (DC) achieves sub-microsecond jitter tolerances by aligning multi-axis trajectory generation in high-speed packaging, electronic assembly, and pick-and-place machines.
