Product Description:

The PY0A100A0P31P00 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. Designed for position-focused motion systems, the unit conditions drive power and processes feedback so a matched servo motor can track commanded positions with minimal lag. It is suitable for control cabinets in automated assembly lines, pick-and-place machines, and material-handling systems where compact power conversion and precise closed-loop control are required.

Electrical input is accepted from a three-phase mains supply, and the amplifier’s power stage supports frequency responses up to 400 Hz, allowing rapid current modulation for high-speed servo loops. Position feedback is processed through a 2000 P/R wiring-saving incremental encoder, while the position control interface accepts target-angle commands directly from a motion controller. Closed-loop velocity is adjustable across a 1:5000 range, providing fine resolution at low speeds without sacrificing high-speed performance. Regenerative energy created during deceleration is dissipated internally by a built-in resistor rated for 90 W. A cooling fan directs air across the power components to manage operating temperature. An integrated dynamic brake helps stop the connected motor promptly when braking is required, and the 100 mm-wide housing supports compact panel arrangements.

For installations requiring greater braking capacity, an external regenerative unit can be connected to channel up to 3000 W of excess energy away from the amplifier. The internal regenerative path uses a 10 Ω dump resistor, allowing compatible auxiliary braking equipment to be selected for the external connection. The enclosure has a height of 235 mm and a weight of 6.0 kg, which supports stable mounting without occupying excessive cabinet space. Regenerative control, braking control, and monitoring circuits are integrated into the amplifier, reducing the number of separate components and field connections needed within the panel.
