Internal Product Review
The QS1A03AA03501P00 is a Sanyo Denki Q SANMOTION servo amplifier built around an IGBT PWM sinusoidal drive and a 1:5000 speed control range. High-response motion performance is supported by a 5M pulse/s maximum pulse frequency and 600 Hz frequency characteristics. Strong dynamic braking with 360 J energy capacity stands out as a key advantage for demanding axis control.

Product Description:
The QS1A03AA03501P00 is a compact servo amplifier from Sanyo Denki and belongs to the Q SANMOTION Servo Amplifiers series. It interfaces with rotary or linear servomotors and receives command signals from motion controllers. The amplifier converts those signals into precisely modulated stator currents so that industrial axes can track programmed velocity, torque, or position profiles without mechanical drift.
Internal electronics consume only 30 VA of control power, and the output bridge employs an IGBT PWM sinusoidal drive topology that minimizes motor torque ripple. For pulse-train control, the amplifier accepts reference inputs up to 5 M pulses/s; when quadrature encoding is used, the maximum input rate is 1.25 M pulses/s. Closed-loop regulation spans a speed ratio of 1:5000, allowing the same motor to run from creeping feed rates to full rated speed while maintaining control accuracy. Analog interfaces include a DC ±2.0 V speed command and a DC ±2.0 V torque command. The monitor outputs reproduce current at 2.0 V ±10% of full scale and shaft speed at 2.0 V ±10% per 1,000 rpm. During rapid deceleration, the internal dynamic-brake resistor absorbs up to 360 J of kinetic energy, helping prevent DC-bus overvoltage.
A peak control inrush current of 40 A (0-P) is tolerated at power-up, after which steady leakage is limited to 0.5 mA per motor to reduce the likelihood of ground faults. If an emergency stop is triggered, the dynamic brake engages within 10 ms to bring the connected motor to a controlled stop. The drive has a frequency response of 600 Hz when the load inertia equals the motor inertia, supporting responsive servo-loop operation. Diagnostic terminals provide velocity and current signals through a buffered monitor with an output resistance of 1 kΩ, allowing oscilloscope measurements without significantly loading the circuit. The housing weighs 1.6 kg, which reduces the mounting load within compact control panels and mobile equipment.
