Product Description:

The PY2A015A3M61P00 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. Designed as the drive interface for the P50B05020D brushless servo motor, it accepts position commands and converts them into regulated phase current so automated axes can index, dwell, and return under closed-loop control. Within an assembly cell or feeder line, the unit links motion controllers to the motor windings, providing current shaping, velocity control, and fault monitoring that simplify the integration of precise mechanical movement into larger industrial automation systems.

The power stage supplies up to 15 A of continuous current from a 200 VAC line. Because the input is single-phase, standard control-panel feeders can be used instead of three-phase mains. Apparent power demand remains at 0.8 kVA, allowing the use of smaller breakers and transformers. The current-loop bandwidth reaches 400 Hz, so torque commands can follow rapid motion profiles. A built-in dynamic brake handles stop events, but no internal regenerative resistor is fitted. Surplus energy must therefore be dissipated through an external resistor when load inertia is high. The feedback port works with 2,000-pulse-per-revolution encoders, and the position-control interface accepts differential pulse trains.

Pulse reception capacity peaks at 2 million pulses/s, enabling finely resolved positioning without lost increments over long move sequences. During rapid deceleration, the braking circuit can absorb 360 J before reaching its duty-cycle limits. The control section draws only 40 VA, separating low-level electronics from the high-power path. A mass of 1.5 kg simplifies cabinet mounting, while heat dissipation of 22 W helps limit enclosure temperature increases. The amplifier does not provide a ready output signal, so machine logic must obtain operating status through alternative input and output lines.
