Product Description:
The PY2A015A2M81P00 servo amplifier is manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. The unit conditions incoming AC power and pulse-train references so that paired Super BL servo motors receive tightly controlled armature current and speed feedback. By converting digital position commands into drive current, it supports pick-and-place axes, indexing tables, and small gantry systems used throughout industrial automation.
Its amplifier capacity is rated at 15 A, establishing the maximum continuous phase current the drive can deliver. The main circuit accepts three-phase 200 VAC, while the logic board runs from a single-phase 200 VAC input, separating the control electronics from the power-switching components. A built-in dynamic brake stops motor motion. The brake transistor engages 10 ms after a stop command, and the brake can absorb 360 J of kinetic energy before reaching its thermal limit. Because no regeneration resistor is integrated, excess energy is handled only by this brake. Speed and position feedback are read through an incremental sensor with a resolution of 2,000 pulses per revolution, matching the drive’s 400 Hz frequency characteristic for stable servo gain. The velocity monitor terminal outputs 0.5 V ±20% to represent real-time shaft speed for external indicators or data capture.
The position-control interface accepts pulse-direction or quadrature reference streams at up to 2 million pulses per second, allowing submicron moves on fast linear stages. Closed-loop velocity regulation spans a range of 1:5,000, permitting slow creep motion as well as rapid transfers without retuning. The amplifier has a vibration rating of 0.5 G, allowing it to tolerate moderate cabinet oscillations in mobile or high-impact machinery. With a mass of 1.5 kg, it can be mounted on DIN rails or panels without heavy support hardware.
