Core Features

• 50 kW High‑Power Conversion: Delivers stable 560 V DC link with near‑unity power factor (cosφ ≈ 1) and low harmonic distortion, reducing reactive power and energy costs for heavy loads.

• Ultra‑High Overload Capability: 250% nominal power for 1 second, ideal for high‑acceleration/deceleration cycles and peak load demands in dynamic machinery.

• Integrated Sinusoidal Regeneration: Returns braking energy to the grid with clean sinusoidal current, minimizing heat loss and improving system efficiency by up to 30% in cyclic operations.

• Standard Brake Chopper: Activates during grid faults or extreme deceleration to dissipate excess energy, preventing DC link overvoltage and protecting connected drives.

• High Power Density: 120 mm width delivers 50 kW, optimizing cabinet space while supporting up to 12 axis modules (standard) or 15 axes (with SEW application approval).

• High‑Speed SBUS⁺⁺ Communication: Enables real‑time synchronization, parameter exchange, and diagnostics with MXM, MXA, and MXC modules, supporting motion cycle times as low as 125 µs.

• Advanced Diagnostics: Equipped with a 7‑segment display and multi‑color LEDs for status, voltage, current, and fault monitoring, simplifying commissioning and maintenance.

• Modular Tool‑Free Installation: Snaps directly to other MOVIAXIS® modules via backplane connectors, reducing wiring effort and enabling fast system expansion or replacement.

• Comprehensive Protection: Includes overvoltage, undervoltage, overcurrent, overtemperature, short‑circuit, and ground‑fault protection for robust operation in harsh industrial environments.

Typical Applications

• Heavy Machine Tools: High‑power CNC machining centers, gantry mills, and heavy lathes requiring sustained power and high overload capacity.

• Material Handling: Large cranes, hoists, and heavy conveyors with frequent lifting/lowering cycles and high inertia loads.

• Metals Processing: Rolling mills, extrusion lines, and stamping presses with high‑force, cyclic motion demands.

• Packaging & Processing: Large forming, filling, and sealing lines with multiple synchronized high‑power axes.

• Printing & Converting: High‑speed web presses, roll‑to‑roll processing, and slitting machines with high inertia and precise motion control.

• General Industrial Automation: Any 50 kW multi‑axis servo application demanding high power, energy efficiency, and reliable regenerative operation.
