Product Description:
The GADSA01AB22 is a compact AC servo amplifier produced by Sanyo Denki for the G Sanmotion AC Servo Amplifiers series. It converts command signals from a motion controller into controlled current and voltage for a matched servo motor, allowing precise velocity and position control in packaging lines, pick-and-place stages, and small conveyors. By integrating the drive and regenerative circuitry in one housing, the unit simplifies cabinet layouts and provides the amplification required for low-power industrial automation.
The amplifier has a maximum instantaneous line current capacity of 10 A, while its continuous output remains at 1.2 Arms for thermal stability during normal duty cycles. For axes rated up to 200 W, the power section can deliver enough energy to accelerate light rotary or linear loads, while the overall power supply demand is only 0.4 kVA. Regenerative energy is handled internally by a built-in resistor rated at 5 W and 25 Ω. A separate external resistor with a minimum resistance of 25 Ω can be added when braking duty exceeds the capacity of the internal resistor. The control circuit draws 0.5 Arms, and the interface accepts analog or pulse references. Sourcing-type GPO terminals provide field I/O connections, and the STO safety function operates without a delay during emergency stops.
During rapid indexing, the amplifier can reach a peak output of 4.3 Arms for short bursts. The velocity loop maintains a ratio of 1:5000, providing fine speed resolution across the motor’s operating range. The amplifier tolerates shocks up to 20 m/s², helping it remain stable when installed on moving machine frames or equipment exposed to sudden mechanical impacts. It also withstands vibration levels up to 6 m/s² during operation. The integrated regenerative circuitry keeps braking-energy management within the amplifier housing and reduces the amount of external wiring required in the cabinet. Sourcing GPO outputs can connect directly to compatible optically isolated inputs without requiring additional switching transistors.
