Core Features

• 25 kW High‑Efficiency Conversion: Near‑unity power factor (cosφ ≈ 1) and low harmonic distortion reduce energy costs and stabilize the DC link under heavy, variable loads.

• Variant 01 Specialization: Optimized for high‑noise industrial environments with upgraded EMC filters; reinforced brake chopper handles higher peak braking energy for frequent stop‑start cycles.

• Full Regenerative Energy Recovery: Returns braking energy to the grid via sinusoidal current shaping, eliminating wasteful resistor heating and improving system efficiency by up to 30% in cyclic applications.

• Compact High Power Density: 80 mm width delivers 25 kW, saving cabinet space and enabling modular, scalable system design for up to 8 standard axes (10 with SEW approval).

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

• Advanced Diagnostics: 7‑segment display and multi‑color LEDs monitor status, voltage, current, and fault codes for simplified commissioning and maintenance.

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

• Comprehensive Protection: Overvoltage, undervoltage, overcurrent, overtemperature, short‑circuit, and ground‑fault protection; variant 01 includes enhanced surge protection for grid‑side voltage spikes.

Typical Applications

• Heavy Machine Tools: High‑power CNC machining centers, milling machines, and lathes in electrically noisy factory environments.

• Material Handling: Cranes, hoists, and heavy conveyors with frequent lifting/lowering cycles requiring robust braking and noise immunity.
