Product Description:

The PY0A015A1FD1P01 servo amplifier is produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. This unit conditions AC input and delivers controlled current to a matched brushless servo motor, enabling precise axis regulation in automated handling equipment, semiconductor tools, and pick-and-place gantries. By integrating command decoding and motor power stages inside a compact chassis, it simplifies cabinet layouts and shortens wiring runs in industrial automation cells.

The power section is rated at 15 A, giving the amplifier enough current to accelerate medium-frame servo motors without external boosters. A sine-wave drive topology modulates the output so the motor receives a near-pure sinusoid, which reduces torque ripple and audible noise compared with trapezoidal switching. The input stage accepts single-phase mains, allowing installation where three-phase service is unavailable. Motion instructions are processed through a position-control interface that interprets directional pulses and enables closed-loop moves with submicron repeatability. Command streams can reach 2.6 M pulses/s, so high-speed indexing tables operate without losing counts. A built-in dynamic brake dissipates kinetic energy during sudden stops, while the regenerative processing circuit channels surplus power back to the DC bus to minimize heat.

Feedback compatibility centers on a 2000 P/R scale received from a wiring-saving incremental encoder, eliminating separate power leads and simplifying cable sets. For applications using dual-phase pulse outputs, the comparator stage accepts reference rates up to 1.0 M pulses/s, preserving accuracy when the controller divides position data across two channels. The housing weighs 2.2 kg, so it can mount directly to machine panels without additional supports. Its compact form reduces the panel area required for each controlled axis. The integrated command and power stages also reduce the number of separate components required inside the enclosure.
