PZ1A050SXXGC00 by Sanyo Denki

The PZ1A050SXXGC00 by Sanyo Denki is a high-performance servo amplifier within the PZ BL Super Servo Amplifiers series, designed to meet demanding industrial automation challenges. This unit accepts a Input Voltage of 3-phase AC 200 V and delivers a Output Current of approximately 50 A through Output Voltage PWM-driven motor outputs. With an efficiency rating of 6550%, the amplifier ensures minimal power loss and sustained performance under heavy loads. It supports both Control Inputs (digital and analog) and features a sturdy panel mount Mounting configuration for seamless installation. Operating reliably from 0 °C to 50 °C, this servo amplifier combines robust engineering and smart protection strategies.

Technical capabilities of the PZ1A050SXXGC00 include a precision PWM-driven three-phase output that optimizes torque and speed control, backed by Protections against Overvoltage, Overcurrent, and Overload detection. The built-in Cooling Method relies on an integrated Fan to maintain safe junction temperatures and ensure continuous duty cycles. The amplifier’s signal processing architecture uses large and small ICs for efficient memory and logic handling, enabling rapid response to motion commands. Connectivity is enhanced via an RS-232/RS-485 port, allowing advanced parameter tuning and real-time monitoring. A compact 235 mm × 75 mm × 235 mm footprint with 50 mm fixing depth streamlines system integration.

Operational features emphasize user convenience and diagnostic clarity. Power input terminals labeled R, S, and T secure the AC supply, while motor output terminals U, V, and W feed the servo motor. Command and feedback lines are provided through CN1 and CN2 connectors, supporting encoder links for position verification. A reset switch (SW3) allows rapid system recovery after fault conditions, with diagnostic LEDs indicating power status and alarm states at a glance. The device’s high efficiency and accurate voltage calibration via onboard trimmers reduce thermal stress and optimize performance in repetitive or high-duty applications.

Integration into complex automation systems is straightforward, thanks to the PZ BL series’ compatibility with standard CNC, PLC, and motion controllers via RS-232/RS-485 communication. Its panel mount design and 200 V AC three-phase input make it ideal for retrofit or new installations in machine tools, robotics, and conveyor systems. By combining advanced protection features, precise control inputs, and robust cooling, the PZ1A050SXXGC00 elevates system reliability and throughput. Engineers can rely on its proven architecture to enhance productivity across a wide range of industrial automation applications.
