PDT-203G-29N
by Sanyo Denki
The Sanyo Denki PDT-203G-29N servo amplifier is a member of the PDT San Driver Servo Drives series, engineered to deliver precise motion control in industrial environments. This device type operates on a rated voltage of 200–230 VAC, 3-phase power supply and provides a rated output current of 20–30 A for driving AC servo motors. The drive supports resolver/encoder compatible feedback inputs, ensuring accurate position and speed monitoring. Housed in a rugged, panel or rack mountable enclosure, the PDT-203G-29N is designed for seamless integration into control cabinets and machinery. Developed by manufacturer, this servo amplifier combines advanced control capabilities with robust protection mechanisms to meet the demands of modern industrial automation systems.
Performance is optimized through vector control algorithms that manage torque and speed with high precision, while the drive’s high-frequency response enables rapid adjustments to dynamic load changes. The internal fan or forced-air cooling system maintains an optimal operating temperature range of –10°C to +55°C, balancing thermal efficiency with compact form factor. With an overall efficiency of 88%, the amplifier minimizes power losses and heat generation during continuous operation. Communication is facilitated via an analog & digital interface (RS-422, CANopen), providing flexible connectivity to PLCs, HMIs, and other networked devices. The PDT-203G-29N also includes a suite of built-in safeguards—overcurrent, overvoltage, and overtemperature protection—to prevent system failures under fault conditions.
Reliability is further enhanced by an IP20–IP54 rating that protects internal electronics from dust ingress and light water splashes, ensuring uninterrupted performance in challenging industrial settings. The drive’s dual-fuse design, featuring 10 A and 1 A input fuses, adds an extra layer of safety against catastrophic overcurrent events. Its robust construction and standardized mounting make it ideal for high-speed packaging lines, robotics, CNC machinery, and printing equipment. Integration into existing systems is straightforward thanks to the drive’s versatile control interfaces and compact footprint. Overall, the PDT-203G-29N excels in applications requiring precise vector control, rapid response, and long-term reliability in industrial automation.
