PRDU-0202-M

The Okuma PRDU-0202-M from the Okuma MDU Servo Drives series is a high-power industrial servo drive engineered for precision motion control in demanding automation environments. It delivers 25 kW power output at an operating input of 400 VAC, providing robust drive capability for high-load applications. Equipped with a ball spline mechanism for linear motion control, the PRDU-0202-M achieves smooth and accurate positioning with minimal mechanical backlash. Its closed-loop control system integrates real-time position and speed feedback to maintain precise adherence to setpoints under dynamic load conditions. This drive carries full CE, UL, and RoHS certifications, underscoring its compliance with international safety and environmental standards.

The PRDU-0202-M’s technical architecture features a closed-loop control type that supports encoder or resolver feedback for continuous position and speed adjustment. It employs a ball spline mechanism to deliver linear motion control, and its precision servo drive function caters to CNC and automation tasks. The device dimensions are 300 x 200 x 100 mm, and it weighs approximately 5 kg in its base configuration, with optional enclosures adding up to 12 kg. Its power conversion efficiency is rated at 95%, minimizing input-to-output losses and thermal dissipation. The protection design is tailored for harsh industrial environments, ensuring stable operation in contaminated or high-humidity conditions. Response time is classified as fast dynamic response, enabling high-speed positioning accuracy. A real-time feedback control loop continuously monitors and corrects motor speed and position.

Operational performance centers on rapid acceleration and deceleration profiles supported by the high-torque capacity of the drive and the low-friction ball spline mechanism. Fast dynamic response ensures that the system can adapt to sudden load variations and command changes with minimal overshoot or settling time. High efficiency reduces internal heat generation, enhancing reliability and extending service intervals. The closed-loop feedback architecture maintains tight control of motor speed across varying loads, while the robust protection scheme guards against voltage spikes and environmental contaminants. Continuous real-time monitoring of position and speed parameters enables predictive maintenance and reduces unplanned downtime.

System integration is facilitated through standard industrial communication interfaces and compatibility with leading CNC controllers and PLC platforms. The PRDU-0202-M enables seamless incorporation into complex multi-axis machining centers, robotic handling systems, and precision assembly lines. Its compliance with CE, UL, and RoHS regulations simplifies global deployment in sectors such as machine tool manufacturing, metalworking, and industrial automation. The drive’s modular design and configurable feedback options make it an ideal solution for applications requiring high-repeatability, dynamic response, and robust environmental resilience.
