Product Description:
The QS1E03AA-01 is a servo amplifier manufactured by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. It serves as the power interface between a motion controller and a three-phase servomotor, regulating current so the motor follows commanded velocity, torque, or position profiles in automated equipment. Three selectable control modes support speed, torque, and position applications without requiring separate amplifiers for each operating method. An IGBT pulse-width modulation system produces a sinusoidal motor current waveform, which helps limit motor heating and audible noise during operation.
This model accepts a single-phase 100 VAC main circuit supply, allowing installation on low-voltage production lines without a step-up transformer. A speed control range of 1:5000 supports precise slow-speed indexing as well as full-speed operation. The frequency response reaches 600 Hz, allowing the control loop to react quickly to changing motion commands. Output current can be observed through a monitor terminal with a scale of 2.0 V at 100% output, providing an accessible signal for waveform checks and drive adjustment. A built-in dynamic brake dissipates motor energy during emergency stops, reducing overrun and helping bring the connected axis to a controlled halt.
The command interface accepts sign-and-pulse signals at up to 5 MHz and quadrature pulse signals at up to 1.25 MHz, allowing the drive to track high-resolution trajectory data from compatible CNC or PLC hardware. Real-time speed feedback is available through a monitor output scaled to 2.0 V at 1000 rpm, enabling an external controller or measuring device to observe shaft velocity without another sensor. Leakage current to ground is limited to 0.5 mA per connected motor, helping control current flow through the protective grounding path. Thermal management is handled by a built-in cooling fan that moves air across heat-producing components during sustained operation. A built-in regeneration circuit manages excess kinetic energy produced by the motor during deceleration. The amplifier can therefore regulate powered motion, monitor operating signals, and manage braking energy through separate internal functions.
