Product Description:
The QS1A01AA0HAA3P0T is a servo amplifier manufactured by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. The module conditions three-phase power, receives high-speed command pulses, and delivers phase-synchronized current to a matched servo motor. Within automated pick-and-place cells and indexing tables, it closes the position loop so the mechanical axis can accelerate, hold, and settle with millisecond precision.
An amplifier capacity of 15 A indicates the continuous phase current that the drive can supply, allowing medium-frame motors to reach full torque without saturation. The power section is fed from a single-phase or three-phase AC 200 V line and uses an IGBT pulse-width modulation system with sinusoidal control to minimize harmonic distortion. A built-in dynamic brake and a separate internal regeneration circuit dissipate excess energy during rapid deceleration, so no external resistor is needed. Command data enter through a position-control interface that accepts pulse trains at up to 5 million pulses per second, while a frequency response of 600 Hz lets the velocity loop follow fast setpoint changes. With a speed control range of 1:5000, the amplifier maintains smooth motion from crawl speed to rated speed. Its 5 G shock resistance supports installation on moving gantries and other machinery exposed to sudden mechanical loads.
The feedback channel uses a wire-saving absolute encoder with an optical sensing method. Within one mechanical revolution, the encoder measures the shaft angle with a 17-bit single-turn resolution. Across multiple revolutions, its internal counter provides a 16-bit multi-turn resolution. Encoder data are transmitted to the amplifier at 2.5 Mbit/s, supporting rapid synchronization with the pulse-width modulation stage. Despite the integrated brake circuitry, the housing weighs only 1.25 kg, which minimizes the load placed on cabinet structures. The compact housing is suitable for installation in articulated robots and space-constrained process equipment.
