Product Description:

The GADSA01LB22 is an AC servo amplifier built by Sanyo Denki for the G Sanmotion AC Servo Amplifiers series. The unit conditions line power and digital command pulses so that a synchronous servomotor receives precisely timed three-phase current. At 0.80 kg, it mounts easily in dense control cabinets and supports positioning tables, pick-and-place arms, and indexing conveyors that require accurate speed and torque regulation in automated production equipment. Its internal logic supports sourcing general-purpose outputs, simplifying connections to relays and compatible control inputs.

The amplifier has a current rating of 10 A, while its continuous output current and required three-phase input current are both 1.2 Arms, keeping heat generation low during steady operating cycles. For fast acceleration, the drive can supply up to 4.3 Arms momentarily, allowing the motor to produce additional torque without requiring a larger power module. Line feeders must deliver 0.4 kVA of apparent power, and an external braking resistor with a resistance of at least 25 Ω is required to dissipate regenerated energy during deceleration. When a three-phase supply is unavailable, a single-phase line draws 2.0 Arms to maintain the same level of performance.

The logic section requires only 0.5 Arms, so a low-capacity control transformer is adequate for this circuit. Motion commands are resolved across a speed range of 1:5000, enabling fine positioning with motors rated up to 200 W. Output terminals use a sourcing general-purpose output scheme, simplifying wiring to compatible PLC inputs, while the safe torque off circuit operates without a delay to shorten the emergency-stop response time. During transport or operation, the housing withstands vibration of 6 m/s² and shocks of up to 20 m/s², helping preserve calibration in mobile or high-impact machinery.
