Product Description:
The QS1A05AA02201T00 is a servo amplifier produced by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. It conditions power and motion commands so that matched servomotors can follow position, velocity, or torque references in automated machinery. The unit uses an IGBT pulse-width modulation sinusoidal drive topology to regulate current supplied to the motor phases. Integrated regenerative circuitry manages excess energy produced by the motor during deceleration.
The control-loop bandwidth reaches 600 Hz, permitting tight tracking of high-speed command profiles, and closed-loop speed can be adjusted across a ratio of 1:5000 without mechanical gearing. A built-in regenerative resistor with a resistance of 17 Ω dissipates surplus energy when the DC bus cannot absorb it quickly enough. During startup, the control section withstands an inrush current of 40 A from zero to peak, while the power stage withstands a maximum inrush current of 18 A from zero to peak. Both inrush events are brief and are limited by dedicated surge circuitry. Thermal management is handled by a side-mounted cooling fan that directs air across the heat sink without increasing the amplifier’s front footprint. The amplifier also includes a dynamic brake that helps stop the connected motor when commanded.
The dynamic brake can absorb up to 1800 J during each stop, making it suitable for applications involving frequent deceleration. High-resolution position commands are accepted through forward and reverse pulse trains at rates up to 5 Mpps, supporting fine interpolation for linear stages and rotary tables. The leakage current is limited to 1.5 mA, helping protect the connected motor and associated equipment. The amplifier has a shock tolerance of 5 G for use in industrial machinery exposed to sudden mechanical forces. A ±8 V monitor output supports oscilloscope diagnostics without interrupting normal operation. The unit also tolerates vibration up to 0.5 G and has a mass of 2.2 kg, which reduces the load placed on the panel mounting surface.
