Functions

High-Precision Positioning: 20-bit incremental encoder (~4M ppr) for ultra-precise feedback. Supports high-resolution position control with Sigma-5 drives.

High Torque and Speed: Rated torque of 28.4 N·m, with 71.6 N·m peak for dynamic loads. 1500 RPM rated, up to 3000 RPM for high-speed operation.

Environmental Durability: IP67 protection for dust and water resistance (excludes shaft). Operates in 0°C to +40°C with 20%-80% humidity.

Medium Inertia Design: Balances responsiveness and stability for applications with moderate load inertia. Suitable for machine tools and transfer machines.

Compatibility: Optimized for Sigma-5 drives but compatible with Sigma-II/III drives with parameter adjustments. Supports torque, speed, and position control modes.

Maintenance: Serial encoder reduces wiring complexity. Main/control circuits separated for easy diagnostics.

Applications

Robotics: High-torque joint control for industrial robots.

CNC Machines: Spindle or feed drives for milling, turning, and grinding.

Material Handling: Heavy-duty conveyors, stackers, and transfer machines.

Packaging Machines: High-speed sealing, cartoning, or palletizing.

Machine Tools: Precision positioning for lathes and presses.

Food Processing: Motion control in harsh environments (IP67).
