Product Description:
The QS1L03AA0MA01S0F is a servo amplifier developed by Sanyo Denki within the Q SANMOTION Servo Amplifiers series. In an automation cell, it interfaces between a motion controller and a rotary servo motor, modulating three-phase power so the motor can follow precise velocity commands for indexing, conveying, or pick-and-place routines. Speed commands enter through the standard interface hardware, and the amplifier regulates motor operation according to the received reference. The compact design allows the unit to serve motion axes that require controlled acceleration, steady travel, and repeatable stopping.
This model supplies up to 30 A of phase current while accepting an input in the 200 V AC class, providing adequate capacity for mid-frame motors used on 200 V mains. A speed-loop bandwidth of 600 Hz allows tight regulation during rapid load changes, and position feedback from a wire-saving incremental encoder is processed at a resolution of 2000 P/R for accurate positioning. Leakage current to ground is limited to 0.5 mA, helping the machine satisfy applicable insulation and grounding requirements. The control circuit receives power from a single-phase supply and processes commands before sending switching instructions to the power stage. A built-in dynamic brake short-circuits the motor windings during emergency stops, while the compatible sensor connection reduces the amount of wiring required between the amplifier and encoder.
Energy produced during rapid deceleration is absorbed by an internal resistor rated at 50 Ω, so an external brake resistor is unnecessary for most operating cycles. The speed loop can maintain stable operation across a 1:5000 control range, enabling slow jogging and high-speed travel without gain changes. Despite its current capacity, the amplifier weighs only 1.3 kg, simplifying panel layout and making the unit easier to handle during installation. The power stage uses an IGBT PWM sinusoidal drive scheme, which reduces torque ripple and acoustic noise compared with square-wave drives. Control power comes from single-phase AC, and the amplifier supports rotary motors from the Sanyo Denki SANMOTION servo families.
