Product Description:
The GADSA02AB22 is an AC servo amplifier produced by Sanyo Denki within the G Sanmotion AC Servo Amplifiers series. It functions as the power stage between a motion controller and a 200 VAC-class servomotor, converting command signals into regulated phase current so that industrial machines can position loads with precise speed and torque control. Commands can be transmitted through analog velocity references or high-resolution pulse trains, providing direct connectivity to common motion-control systems.
The power section accepts an input of 200 to 240 VAC at 50/60 Hz and has an amplifier capacity of 20 A. During continuous operation, it delivers 3.1 Arms to the motor, while an internal DC link is maintained at 300 VDC ±20% for energy storage and rapid current response. When paired with a matched motor, the unit can supply up to 400 W of mechanical output, supporting medium-sized axes such as pick-and-place heads or indexing tables. The three-phase input current is 2.2 Arms, while the input current is 3.9 Arms when the amplifier is powered from a single-phase source. This input flexibility supports cabinet wiring in facilities where only single-phase feeders are available. The amplifier belongs to the 200 VAC voltage class, allowing it to operate with common low-voltage power distribution networks.
Dynamic demands are met by a peak output of 12.0 Arms, and excess kinetic energy is absorbed by a built-in regenerative resistor rated at 17 Ω, eliminating the need for an external brake module. The required supply capacity is 0.8 kVA, indicating the apparent power that the mains must furnish under full load. A velocity control range of 1:5000 enables fine speed regulation from slow movement to rated speed. Sourcing-type general-purpose outputs support connections to field devices. A Safe Torque Off channel has a delay of 0–20 ms, while analog and pulse interfaces provide connectivity to PLC motion cards.
