Product Description:

The QS1A03AA048A3PAR servo amplifier is produced by Sanyo Denki as part of the Q SANMOTION Servo Amplifiers series. It converts the fixed-frequency factory supply into a controlled three-phase output that tracks motion commands from CNC or PLC hardware, adjusting current and voltage according to the target position, velocity, and torque. By closing these control loops in real time, the amplifier allows industrial robots, packaging gantries, and pick-and-place actuators to maintain repeatable trajectories in multi-axis automation cells.

The power stage has an amplifier capacity of 30 A, allowing the drive to deliver peak phase current to mid-frame servo motors without saturation. It operates from an AC 200 V supply, and its input filter supports a frequency response of 600 Hz so the current loops can follow rapid command changes. Position data can be streamed at up to 5 million pulses per second. Combined with an electronic speed control range of 1:5000, this rate permits smooth low-speed indexing and high-speed movement on the same axis. Command references are accepted as DC ±2.0 V signals for both speed and torque modes, while matching 2.0 V ±10% monitor outputs provide real-time feedback to upper-level controllers. A dedicated leakage-current path limits discharge current to 0.5 mA to support compliance with insulation requirements.

The protection circuit is coordinated with a panel-mounted circuit breaker rated at 10 A, while control-circuit inrush is limited to 40 A (0-P) to prevent nuisance tripping during power-up. The main power stage draws a maximum inrush current of 18 A (0-P). A dynamic brake module can absorb up to 360 J of regenerated energy and engages after a delay of 10 ms. Internal sensors supervise continuous operation, while the 2.0 V monitor channel provides speed feedback for the connected controller. The chassis weighs 1.6 kg, which reduces the load placed on cabinet mounting surfaces and support hardware.
