Product Description:

Sanyo Denki’s QS1A03AA036A3PA1 servo amplifier is part of the Q SANMOTION Servo Amplifiers series. The module commands a rotary servo motor in industrial automation by accepting motion instructions from a host controller and issuing regulated output that aligns rotor position, velocity, and torque with programmed demands. Its role is to close the electromechanical control loop in production lines that require precise positioning, such as electronic component insertion, palletizing cells, and labeling systems.

The drive delivers a continuous output of 30 A through an IGBT PWM sinusoidal drive topology that minimizes current ripple and acoustic noise. An internal dynamic brake and a built-in regeneration circuit dissipate excess kinetic energy during rapid deceleration, protecting both the amplifier and the connected motor. Position control operates with a frequency response of 600 Hz, allowing the axis to follow tight trajectory commands with minimal lag. Command data arrive as differential pulses at up to 5 million pulses per second, while the power stage operates from a single-phase 200 V AC supply, simplifying wiring in light-duty panels. Feedback is returned through an optical, wire-saving absolute sensor that uses a half-duplex start-stop format, so only two signal cores are required between the amplifier and the motor.

The speed control range reaches 1:5000, enabling stable rotation from creep speeds to rated velocity without manual gain changes. Digital feedback travels over a sensor bus rated at 2.5 Mbit/s, and position data are delivered with 17-bit/16-bit resolution to support sub-arcminute accuracy on gear-driven axes. An inrush-current limiting interval of 1,800 ms moderates current during power-up, reducing electrical stress on internal components. The amplifier’s aluminum housing weighs 1.6 kg, making the unit easier to install on moving carriages or inside compact cabinets. Its compact construction also reduces the mounting load where available panel space is limited.
