Product Description:

The PY2A015A3M21P00 is a servo amplifier from Sanyo Denki in the PY Super BL Servo Amplifiers series. It supplies power and closed-loop drive signals to Super BL servo motors and integrates with motion controllers to regulate axis position and speed in automated production lines. By converting incoming three-phase mains power into precisely modulated current, it maintains the torque, velocity, and position accuracy required for pick-and-place, packaging, and electronic assembly equipment.

The amplifier can deliver a continuous output of 15 A, providing the current capacity needed for medium-frame servo motors. During startup, its control circuitry momentarily draws 40 A of inrush current, while steady-state logic consumption remains at a control power capacity of 40 VA. The power stage handles up to 0.3 kVA, so the cabinet power supply must accommodate this rating. A frequency response of 400 Hz allows the velocity loop to track rapid command changes without overshoot. A velocity control range of 1:5000 supports precise low-speed indexing as well as high-speed movement. Position data are exchanged through a position control interface, and the 168 mm height and 135 mm depth allow the unit to fit in shallow, high-density panels.

A built-in dynamic braking circuit engages 10 ms after a stop command and can absorb 360 J of kinetic energy, eliminating the need for an external regenerative resistor under most load conditions. On the mains side, the converter experiences a peak inrush of 23 A, so upstream protection devices must be selected accordingly. Shaft feedback from the matched motor is decoded at 2000 P/R, providing sufficient resolution for fine positioning without placing an excessive processing load on the controller. Despite these capabilities, the amplifier dissipates only 16 W of heat at rated load, easing thermal management. The enclosure weighs 2.2 kg, which helps reduce panel mass in multi-axis systems.
