Product Description:
The QS1L01AA042A3PAR is a compact servo amplifier produced by Sanyo Denki within the Q SANMOTION Servo Amplifiers series. Designed for closed-loop motion platforms, the unit conditions command pulses from CNC, PLC, or robot controllers and modulates motor phase currents so a servo axis can accelerate, hold speed, or maintain position under varying loads. By integrating power switching, feedback processing, and protective features, it streamlines drive cabinet layouts in assembly machines, pick-and-place gantries, and semiconductor handling equipment.
Its power stage employs an IGBT PWM sinusoidal drive topology that minimizes torque ripple while responding to velocity commands. The internal line receiver accepts differential RS-422 signals, and the pulse input port tracks edges at up to 5 Mpps, permitting high-resolution electronic gearing. A selectable hardware multiplier can expand incoming pulse density by 63×, reducing controller bandwidth demands. Velocity regulation spans a ratio of 1:5000, and the speed loop bandwidth is specified at 600 Hz, allowing tight contouring on fast axes. The monitor terminal supplies up to ±8 V in proportion to setpoint or feedback values. Overcurrent protection uses a DC ±2.0 V ±15% limit reference. The built-in dynamic brake and regeneration circuit dissipate excess energy during deceleration.
Leakage current is limited to 0.5 mA, helping the amplifier meet ground-fault safety requirements. Control wiring is clamped to the terminals with a tightening torque of 1.18 N·m. The housing has a width of only 45 mm, so multiple amplifiers can be mounted side by side on a DIN rail. The chassis has a mass of 1.25 kg, which eases handling during panel assembly. Separate analog outputs use a ±2.0 V ±20% scale for speed and torque monitoring, providing a direct view of motor load without requiring a network connection.
