PY2A050E4XXYPH3 by Sanyo Denki

The Sanyo Denki PY2A050E4XXYPH3 amplifier is a high-performance member of the PY Super BL Servo Amplifiers series designed for demanding industrial automation environments. This model excels in velocity, torque, and position control with precise command handling for CW/CCW or pulse + direction modes. It accommodates main circuit power input of three-phase 200–230 VAC (+10%/–15%), 50/60 Hz ±3 Hz and provides robust control under varied load conditions. With a compact footprint and advanced protection functions, it ensures reliable operation in complex motion control systems. Key capabilities include support for differential line driver inputs, multiple sequence I/O signals, and high-speed absolute encoder interfaces.

This unit’s technical specifications deliver comprehensive performance metrics for integration into precision systems. It operates in ambient temperatures of 0 °C to 55 °C with an operating/storage humidity up to 90% RH (no condensation). The control circuit power input is single-phase 200–230 VAC (+10%/–15%), 50/60 Hz ±3 Hz and the mass is approximately 2.7 kg. Dimensions are height 168 mm (excl. mounting fittings) and depth 135 mm, enabling flexible panel mounting. Critical protection mechanisms include overcurrent, overload, power & sensor error detection, and overheat/overspeed thermal and speed protection. Connectivity is achieved via connector-type terminals for high-voltage I/O wiring and the device sustains vibration tolerance of 0.5 G, 10–55 Hz for 2 h across XYZ axes.

Operational features are optimized for precise motion control and resilience in production settings. Input command handling reaches a 2.6 MHz max input pulse frequency with a minimum pulse width of 192 ns for differential line signals. It supports 2-phase pulse trains at up to 1 MHz with 90° phase difference. The amplifier’s ±2.0 V DC current limit input (±10% of rated armature current) allows fine-tuned torque control. An adjustable electronic gear ratio from N/D = 1/32767 to 32767/1 scales command signals to match motor characteristics. Position output configurations include N/8192, 1/N or 2/N formats, and absolute encoder communication at 9600 bps start/stop or 1 Mbps/2 Mbps Manchester. The device maintains a velocity control range of 1:5000 for broad speed adaptability.

System integration is streamlined for modern industrial applications through standard sequence inputs—servo ON, alarm reset, rotation inhibit, encoder clear, and proportional control—and outputs such as motor ready, alarm code, clamping brake timing, and zero deviation signals. Targeted applications span CNC machine tools, robotics, packaging machinery, and assembly systems requiring high throughput and minimal downtime. The PY2A050E4XXYPH3’s combination of high-speed command processing, comprehensive protection features, and flexible I/O makes it an ideal solution for sophisticated motion control architectures within factory automation environments.
