PY9A150U0XXXC08 by Sanyo Denki

The PY9A150U0XXXC08 from Sanyo Denki is an advanced servo amplifier in the PY Super BL Servo Amplifiers series, engineered for high-power precision control. This amplifier delivers a Rated Output of 4500 W and supports a Rated Torque of 21.5 N·m with a Continuous Stall Torque of 32.0 N·m. It is optimized for a Rated Revolution Speed of 2000 rpm and a Maximum Revolution Speed of 2500 rpm, ensuring broad operational flexibility. The drive accommodates a Rated Armature Current of 24.1 Arms and can handle a Continuous Stall Armature Current of 31.6 Arms, offering robust current capacity for demanding applications. As a 200VAC amplifier designed for 3-phase amplifier configurations, this unit integrates seamlessly into industrial power infrastructures for precise motor control.

Performance is enhanced by a peak Instantaneous Maximum Stall Armature Current of 79.7 Arms and an Instantaneous Maximum Stall Torque of 70.0 N·m, enabling rapid load response and high torque surges. Regenerative processing minimizes power dissipation during braking, while the auto-tuning function adapts gain parameters both in offline and online modes to match load inertia accurately. Built-in rush prevention and remote operation capabilities protect the system during start-up transients and facilitate integration into centralized control networks. Control mode switching among speed, torque, and position modes ensures versatile operation across a spectrum of motion profiles. The drive’s robust design supports reliable feedback loops and tight servo loops for dynamic performance.

Reliability is assured by operation over a wide ambient range up to 55°C for the amplifier and compliant monitoring to protect motors rated to 40°C. For critical uptime applications, the unit recommends connection to an uninterruptible power supply (UPS) for stable 200VAC input. Its compact footprint and standardized interface allow straightforward integration with Sanyo Denki PXX series servo motors and third-party actuators. The PY9A150U0XXXC08 is especially suited for high-inertia loads and large servomotors up to 150 A capacity, making it ideal for automated assembly, robotics, packaging machinery, and precision positioning tasks. Continuous diagnostics and protective features ensure long-term stability and predictable maintenance scheduling.
