Product Description:

The QS1A15AA03GA3P0R servo amplifier is manufactured by Sanyo Denki within the Q SANMOTION Servo Amplifiers series. In a motion system, this device supplies controlled current to a matched servomotor and interprets incremental feedback to close the speed and position loops. It serves as the intermediary between a motion controller and the mechanical load, shaping pulse trains and analog references into three-phase outputs that keep production equipment synchronized. Compact construction with integrated regeneration and braking elements allows the module to streamline cabinet layouts in high-throughput packaging, electronics placement, and material-handling machines.

A built-in 6 Ω regeneration resistor converts excess kinetic energy into heat during deceleration, while the braking circuit begins clamping only 24 ms after a stop request, preventing overvoltage on the DC bus. The network can absorb up to 2450 J before external dumping is required. An IGBT PWM sinusoidal drive topology shapes the motor phases, and the open-loop frequency response extends to 600 Hz, supporting accurate velocity tracking. Command interface capacity reaches 5 M pulse/s, giving high-resolution pulse trains from modern motion controllers direct access to the amplifier. Analog inputs accept speed and torque references of DC ±2.0 V, and internal design holds motor leakage current to 3 mA to meet safety leakage limits.

For slow creep moves as well as rapid positioning, the amplifier offers a 1:5000 speed control range that remains linear across the analog channel. Encoder feedback is exported through a divisor of N/8192, allowing host controllers to monitor coarse or fine motion without extra hardware. Mechanical integrity is verified to 5 G of shock and 0.5 G of continuous vibration, ensuring stable electronics on stamping or pick-and-place frames. With a mass of 6.8 kg, the enclosure mounts solidly yet remains manageable for single-person installation tasks.
