Core Features

• High‑Efficiency Power Conversion: Achieves near‑unity power factor (cosφ ≈ 1) and low harmonic distortion, reducing reactive power and energy costs while stabilizing the DC link under varying loads.

• Integrated Regenerative Energy Management: Returns braking energy to the AC grid with sinusoidal current shaping, minimizing heat loss and improving system efficiency compared to passive brake resistors.

• 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: Compact 80 mm width delivers 25 kW, saving cabinet space and enabling modular, scalable system design.

• Multi‑Axis Support: Powers up to 8 axis modules as standard; expandable to 10 axes with SEW application engineering approvaleero.

• 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 the backplane connector, 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 industrial environments.
