PB4A002P301

The Sanyo Denki PB4A002P301 servo driver from the PB SANMOTION Servo Drivers series offers precise motion control for both single-phase and three-phase power systems. Designed to accept 200–230 VAC input at 50/60 Hz, this pulse-train input device supports closed-loop control via an encoder for enhanced accuracy and reliability. Its compact design has a mass of 0.65 kg and operates efficiently in ambient temperatures ranging from 0 to +55 °C. The PB4A002P301 provides rotational speed support up to 4500 min⁻¹, making it suitable for high-precision industrial automation equipment. With integrated PWM control for sinusoidal drive and low heat generation, this unit ensures stable performance under demanding conditions.

Detailed electrical and mechanical specifications underscore its robust design. The driver accommodates a power supply current of 4.5 A (single-phase) and 2.5 A (three-phase) and meets a dielectric strength of 1.5 kVAC for 1 minute between the power terminal and frame. Its insulation resistance is rated at 10 MΩ min. at 500 VDC, while the protection class is Class I. The device withstands an operating altitude of up to ≤1000 m above sea level and features an impact resistance of 20 m/s². With a storage temperature range of –20 to +65 °C and operational humidity tolerance of ≤90 % RH (non-condensing), it is engineered for a wide range of environments.

Operational performance is enhanced by vibration resistance of 5 m/s², 10–55 Hz, X/Y/Z axes for 2 h each, ensuring stable motion under mechanical stress. The integrated holding-brake control function secures load positioning without auxiliary devices. A seven-segment LED display provides real-time monitoring and diagnostic feedback, supporting digital operator functions such as auto homing, forward direction, jog operation, and S-filter adjustments. Communication is handled via an RS-485 interface with start/stop synchronization at 115200 bps, enabling streamlined setup and efficient data exchange. Rated for motors up to 4500 RPM, the PB4A002P301 maintains consistent operation even in extended run cycles.

System integration is seamless with its RS-485 PC interface, facilitating parameter tuning and monitoring through standard industrial networks. This driver is ideally suited for precision testing and analytical instruments, searchlight positioning systems, surveillance camera mounts, and semiconductor manufacturing equipment. The combination of compact size, robust protection, and advanced control functions makes the PB4A002P301 an optimal choice for industrial automation applications requiring reliability, accuracy, and efficient heat and vibration management.
