This new series of servo drives is characterized by EtherCAT-based multi-axis synchronization for complex machine applications with a large number of axes, as well as “out-of-the-box” servo auto-tuning, and full frequency range vibration suppression for easy optimization of control performance. The new drives have several new design features, such as vertical thermal ventilation, zero stacking installation, simple wiring, and energy saving through shared AC/DC bus system. The display unit is modular and easy to disassemble and maintain.
