Product Description:

The GADSE02AA22 is an AC servo amplifier produced by Sanyo Denki within the G Sanmotion AC Servo Amplifiers series. It interfaces between a motion controller and a small- to mid-frame servo motor, converting command signals into controlled current and voltage so the motor can follow precise velocity or position profiles in automated machinery. The input section accepts single-phase mains power, simplifying power distribution in compact control cabinets.

This model delivers an amplifier capacity of 20 A, while its continuous output is limited to 3.1 Arms to prevent overheating during steady operation. Short accelerations are supported by a peak current of 12.0 Arms, providing headroom for rapid load changes up to the rated motor shaft power of 400 W. A sinking-type general-purpose output is provided for external fault signaling. The internal design meets overvoltage category III requirements for installation on industrial supply lines. With a mass of 0.80 kg, the unit adds little weight to a control panel and can be securely mounted without requiring extensive structural support.

A built-in 17 Ω braking resistor dissipates regenerated energy and establishes the minimum permitted resistance for an optional external resistor. The regenerative circuit can dissipate up to 20 W during maximum absorption, and the factory-mounted resistor does not require additional wiring. Vibration endurance reaches 6 m/s², while shock resistance reaches 20 m/s², allowing installation on moving gantries or near stamping presses. Dynamic speed regulation spans a ratio of 1:5000, enabling slow indexing and high-speed travel with a single motor and drive combination. An STO input is included without a delay circuit, providing immediate torque shutdown when the safety function is activated. The sinking-type output allows the amplifier to communicate fault conditions to an external control circuit without relying on a separate signaling module.
