The WSD-H3 Series High Performance Servo (ECAT Type) is designed for high-speed, high-precision motion control systems that require real-time communication. Supporting a power range from 50 W to 7.5 kW, it offers flexible single-phase and three-phase AC power options (220 V / 380 V) to suit various industrial environments.
With EtherCAT communication, this model enables fast data exchange, precise synchronization, and stable multi-axis control. High peak current capability ensures rapid response and smooth motion, while selected models feature a built-in brake resistor for improved braking performance and operational safety. It is ideal for robotics, CNC machinery, packaging, and complex automation systems.
