Product Description:

The PY2A030A01B8S01 is a servo amplifier produced by Sanyo Denki in the PY Super BL Servo Amplifiers series. It converts reference signals and three-phase mains power into controlled armature current for a matched Super BL servo motor. This regulated output supports precise speed control in packaging machines, pick-and-place gantries, and other automated equipment where repeatable motion is required.

It delivers up to 30 A of output current, providing headroom for rapid acceleration without saturation. The control electronics operate from a 200 VAC single-phase supply, and inrush current on that line peaks at 40 A, so branch fusing must accommodate short surges during power-up. Heat generated during pulse-width modulation is removed by forced-air cooling. Maintaining at least 0.3 m of unobstructed space along the exhaust path helps keep fan noise low and protects the unit from thermal cutoff. The velocity loop uses internal compensation rated for 400 Hz, allowing responsive speed regulation when combined with the amplifier’s dedicated speed-control interface. The main printed circuit board and power modules are housed in a chassis that is 70 mm wide and 135 mm deep, leaving room for filter boards without crowding adjacent components.

Torque energy is drawn from a 200 VAC three-phase main line, while separate buses for logic and power simplify isolation testing. A built-in dynamic brake dissipates kinetic energy during emergency stops, but the amplifier lacks a built-in regenerative resistor. Long deceleration cycles that exceed the internal thermal limits therefore require an external resistor. Closed-loop operation spans a 1:5000 velocity control range, allowing the same drive to support low-speed positioning and high-speed travel without parameter changes. The amplifier is 168 mm tall and weighs 2.0 kg, making it suitable for direct installation on machine frameworks where cabinet space is limited.
