Product Description:

The QS1A05AN0KEB2A00 is a servo amplifier manufactured by Sanyo Denki and included in the Q SANMOTION Servo Amplifiers series. This unit conditions power for matched SANMOTION servo motors, converting incoming DC into a regulated three-phase output so that closed-loop speed, torque, or position can be applied with precision inside automated equipment such as pick-and-place stations, feeders, or small machining axes. Designed for cabinet installation, the amplifier interfaces with PLC motion controllers and accepts analog command voltages for real-time regulation.

The power stage is rated for continuous output of 50 A, allowing the drive to deliver startup and cutting currents without saturation. A built-in regeneration resistor of 17 Ω converts motor back EMF into heat, eliminating an external braking plate, while an upstream 15 A circuit breaker limits the maximum mains draw. Motion processors can stream incremental pulses at up to 5 Mpps, and the IGBT PWM sinusoidal topology produces smooth phase currents with low acoustic noise. The dynamic brake is released after 10 ms, enabling rapid restart cycles. The controller supports speed, torque, and position loops. Analog inputs of ±2.0 V handle speed and torque commands, the logic section requires 30 VA, and AWG16 control wiring simplifies terminal strip layout.

Thermal absorption during each stop reaches 1800 J, permitting frequent deceleration without overstressing the braking circuit. The main power bus uses AWG12 conductors to keep voltage drop low at high current. Installation strain is minimal because the housing weighs only 1.3 kg. In operation, protective earthing keeps motor leakage current to just 1.5 mA, supporting compliance with equipment safety limits. Its compact housing allows mounting close to the axis in automated cells.
