Product Description:

The PY2A030A3-AL servo amplifier is produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It serves as a drive module that converts fixed AC mains power into controlled three-phase output for brushless servomotors, enabling precise velocity and position regulation in automated pick-and-place heads, electronic assembly lines, and mid-speed packaging axes. By combining current vector control with built-in braking functions, it maintains tight motion profiles while protecting the mechanical load.

The main power supply requires single-phase 200 VAC power. During startup, the control section tolerates a surge current of 40 A, while line filtering keeps harmonics within acceptable drive cabinet limits. The amplifier’s feedback loops sustain a closed-loop bandwidth of 400 Hz, so speed commands from the CNC or PLC are translated into motor torque with minimal delay. Pulse-train interfaces handle command streams as fast as 2.6 Mpps, allowing fine position increments without losing counts. Heat generated by the IGBT bridge is removed through forced-air cooling. The chassis has a depth of 135 mm and fits shallow 200 mm panels, providing layout flexibility in multi-axis racks.

The main inrush current is limited to 23 A, and the maximum ambient operating temperature is 55 °C. Beyond these limits, protective circuits disable the gate drive to prevent thermal runaway. The velocity regulation range is 1:5000, supporting slow indexing and full-speed moves without gain changes. The unit weighs 2.2 kg, and its 168 mm height supports vertical stacking above cooling ducts. A built-in dynamic brake clamps the motor during an emergency stop, while internal regenerative processing returns excess energy to the DC bus. The amplifier does not include a built-in regeneration resistor, so a cabinet-mounted resistor must absorb sustained excess energy. The design also omits a ready-output contact, simplifying wiring in systems that already monitor DC-link status.
