Product Description:
The PY0A015A0SW1P01 is a servo amplifier produced by Sanyo Denki as part of the PY Super BL Servo Amplifiers series. It regulates current and voltage delivered to a matched BL servo motor, executing closed-loop position commands for industrial axes that require precise velocity and torque control. Integrated dynamic braking and encoder feedback connections allow the unit to decelerate loads rapidly and remain synchronized with motion controllers in assembly cells and packaging machines.
The power stage supplies up to 15 A of continuous output and accepts three-phase mains through its input section. During power-up, the main circuit experiences an inrush current of 18 A, while the control circuitry can momentarily draw 40 A; fuses and contactors must accommodate these peaks. Frequency response extends to 400 Hz, permitting stable velocity loops during fast command changes. A dynamic brake relay closes in 6.5 ms, restricting regenerated energy on the DC bus. Position commands arrive through a position-control interface, and an incremental encoder with 2,000 pulses per revolution returns shaft feedback. Under rated conditions, speed deviation caused by load changes remains within ±0.1%, while temperature drift is limited to ±0.5% and voltage variation is held to ±0.1%.
The internal resistor dissipates up to 360 J of kinetic energy each time braking is invoked, preventing overvoltage trips. A power module rated for 200 VAC is equipped with dynamic brake hardware and connects directly to common factory power supplies. Closed-loop speed regulation spans a 1:5000 range, allowing one motor to index slowly during setup and reach full production speed during operation. All components are housed in a chassis that weighs 2.2 kg, simplifying panel installation. The compact enclosure reduces the mounting load on cabinet panels while leaving the amplifier accessible for wiring. Its position-control interface supports applications that require repeatable indexing, coordinated acceleration, and controlled stopping.
