Product Description:

The QS1J03AA0WNA3P01 is a servo amplifier built by Sanyo Denki within the Q SANMOTION Servo Amplifiers series. It governs brushless servomotors in speed, torque, or position modes by means of an IGBT PWM sinusoidal drive architecture, supplying phase-matched current while monitoring feedback from external encoders. In automated cells, the unit handles velocity regulation, manages load-induced torque changes, and executes point-to-point positioning while recycling excess energy through its internal regeneration circuit.

Closed-loop operation has a bandwidth of 600 Hz, so the amplifier can follow command changes and reject load disturbances at that frequency. Analog references enter through a differential input that accepts DC ±2.0 V, and within this range, the drive delivers a proportional speed command. The adjustable loop can maintain motor velocity across a ratio of 1:5000, allowing slow indexing and high-speed travel from the same hardware. Pulse-train interfaces are equally responsive; the position port accepts incremental commands up to 5 Mpps, supporting fine resolution at rapid cycle rates. A command change reaches the motor after only 10 ms of internal delay, combining with the high bandwidth to limit tracking error during dynamic motion sequences.

Built-in safety and diagnostic functions supplement control performance. The dynamic-brake resistor absorbs up to 360 J per event, bringing the axis to rest if power is removed. Leakage current to protective earth is limited to 0.5 mA per motor, aiding compliance with machine safety standards. Differential outputs conform to the RS-422 line-driver standard, reporting real-time speed at 2.0 V ±10% and phase current at the same scaled level for oscilloscope monitoring. All features are packaged in an enclosure weighing only 1.3 kg, easing installation on DIN rails or inside compact control cabinets.
