Product Description:
The PY0A030A0MA1S01 servo amplifier is produced by Sanyo Denki within the PY Super BL Servo Amplifiers series. Designed for compact motion-control cabinets, the unit supplies controlled three-phase power to brushless servomotors and monitors feedback signals in real time. In automated assembly cells, packaging machines, and semiconductor tools, it converts incoming mains power and low-level reference commands into precise motor currents, allowing tight position and speed regulation across multiple axes.
The main power path is rated for three-phase operation, so the amplifier distributes balanced line voltages to each motor winding without additional phase conversion. Its control electronics run on a single-phase source, keeping logic power independent from the motor bus. To maintain conductor temperature and terminal integrity, the main circuit requires a minimum wire cross-section of 2.0 mm². Initial energization draws a main-circuit inrush current of 18 A, while the control section can momentarily draw up to 40 A during capacitor charging. Drive-system circuit breakers and soft-start modules must therefore accommodate both inrush values. When the built-in dynamic brake is commanded, its relay changes state within 6.5 ms, allowing the braking sequence to begin quickly during an emergency stop.
During deceleration, the brake resistor can absorb up to 360 J of returned energy, helping prevent DC-bus overvoltage and protect upstream power supplies. The control loop supports frequency components up to 400 Hz, enabling a stable response when servomotors execute high-bandwidth positioning moves. The amplifier has an overall mass of 2.2 kg, so its tray-type power-supply structure can be mounted on light panel shelves without additional reinforcement. Its compact form also reduces the amount of cabinet space required for each controlled axis. The velocity control ratio of 1:5000 allows the drive to maintain fine speed resolution across a wide operating range, from low-speed motion to full mechanical output. This broad adjustment range supports applications that require both precise indexing and smooth operation at higher speeds.
