Product Description:
The QS1A05AA0MD01S0F is a servo amplifier manufactured by Sanyo Denki as part of the Q SANMOTION Servo Amplifiers series. The device interfaces between a numerical motion controller and permanent-magnet servo motors, converting the controller’s motion commands into regulated three-phase output currents. By providing tight current, velocity, and position loops, the amplifier enables precise axis movement in assembly robots, electronics placement machines, and packaging lines. Its built-in regeneration circuitry manages excess DC bus energy without requiring an external regeneration module.
Rated output current capacity reaches 50 A, supplying ample phase current for midsize servomotors without saturation. When power is first applied, the control circuit draws a peak current of 40 A, and the main power circuit experiences a peak inrush current of 18 A; both values guide fuse and breaker sizing. Regenerative energy is handled internally by a 17 Ω resistor that dissipates excess bus energy, so no external module is required. For rapid emergency stops, the amplifier integrates a dynamic brake that activates in 10 ms and can absorb up to 1800 J of kinetic energy before reaching its thermal limit. Command bandwidth extends to 600 Hz, allowing velocity loops to track high-frequency reference changes without instability.
The amplifier housing weighs 2.2 kg, so cabinet rails can support it without additional bracing. Its structure withstands shocks up to 5 G, helping it tolerate impacts during handling and operation. Continuous operation is permitted from 0 °C to 55 °C, while storage temperatures may reach 65 °C. Leakage current to the motor frame is limited to 1.5 mA, helping the installation meet applicable ground-fault safety thresholds. The speed control algorithm maintains a ratio of 1:5000, enabling fine low-speed positioning as well as full-speed movement.
