GADSA01AB22 by Sanyo Denki

The GADSA01AB22 is an AC servo amplifier produced by Sanyo Denki for the G Sanmotion AC Servo Amplifiers series. Built for single-axis drives, it works with a host controller to regulate motor current so that industrial actuators reach precise positions, speeds, or torques. Its compact frame simplifies panel design in pick-and-place robots, packaging equipment, and other automated lines, and it is intended for cabinet installation where space and wiring density are critical.

Energizing circuitry supplies a continuous 10 A to the motor phases. The control section is powered by 200-240 VAC at 50/60 Hz, or the unit can run from a 300 VDC link when a shared supply is preferred. An IGBT-based sinusoidal PWM bridge shapes the output to reduce harmonic content and acoustic noise. The amplifier supports position, speed, and torque control, enabling a single model to cover diverse load profiles while maintaining tight servo accuracy.

A built-in regenerative resistor absorbs braking energy, removing the need for an external dump. Commands arrive over a Analog/Pulse interface, and two sourcing outputs report status to PLCs. The power stage can draw from the same single-phase AC feed or from the shared DC bus, suiting mixed-voltage cabinets. Continuous duty is specified for 0 to +60 °C ambient and up to 95 % non-condensing humidity. An integrated STO function disables the gate drive for safe torque-off, while no other safety options are included. With one controllable axis and a mass of 0.75 kg, the unit meets tight-footprint machine needs.
