PU-P050B1 by Sanyo Denki

The PU-P050B1 is a precision servo amplifier from Sanyo Denki’s PU Super Servo Amplifiers series, designed for industrial automation and motion control applications. This unit features a Rated Voltage of 100V AC and accepts an Input Voltage of 200 V AC, delivering a Rated Output Current of 13.3 A from a compact Amplifier Capacity of 50A chassis. The amplifier operates in Position control mode and employs a Wiring-saving incremental sensor with 2,000 pulses/rev for high-resolution feedback. It integrates both analog and pulse control inputs alongside an Encoder feedback interface to ensure precise speed and position monitoring. Early incorporation of robust protection circuits guards against overvoltage, undervoltage, overcurrent, and short-circuits to maintain operational integrity.

The performance envelope of the PU-P050B1 is defined by a comfortable operating range of 0°C to 55°C ambient temperature with 20% to 90% RH non-condensing conditions, ensuring reliability across varied environments. Communication is streamlined via dual serial ports (RS-232 and RS-485) along with multi-protocol support including CANopen, EtherCAT, and Modbus for seamless integration into complex networks. The built-in motor disconnection detection and encoder error recognition enhance operational safety, while automatic derating above 1,000 meters maximum altitude preserves performance at elevation. Security features include automatic thermal shutdown to prevent overheating and dedicated hardware overcurrent protection to mitigate load-induced stress. The amplifier’s compact mechanical design and standardized Type Identification: Standard facilitate straightforward mounting within control cabinets.

Reliability is further underscored by a Storage Temperature Range of -20°C to 85°C, enabling resilience during transportation and off-line storage. The module’s robust design meets rigorous industrial standards and supports continuous operation without condensation or icing. Integration into automation architectures is simplified by its versatile I/O set and multi-protocol communication stack, making it suitable for CNC machines, robotics, packaging machinery, and assembly lines. Fault-tolerant features such as encoder error recognition and motor disconnection detection ensure that critical processes are safeguarded against unexpected interruptions. Overall, the Sanyo Denki PU-P050B1 amplifier delivers dependable performance, flexible connectivity, and comprehensive protection for demanding motion control systems.
