Product Description:
The GADSA10AB22 servo amplifier is produced by Sanyo Denki within the G Sanmotion AC Servo Amplifiers series. It occupies the power-conversion layer of an automation axis, taking three-phase AC input power and delivering precisely controlled currents to a permanent-magnet motor. By combining gate control, current feedback, and velocity control loops in one enclosure, the module allows the motion controller to focus on trajectory planning while the amplifier maintains torque accuracy. This arrangement supports precise motor operation in automated machinery that requires coordinated acceleration, positioning, and speed regulation.
Its power section is rated for an instantaneous bus capacity of 100 A, allowing short bursts of mechanical acceleration without saturation. During continuous operation, the inverter supplies 24.0 A rms, while overload events are tolerated up to 55.0 A rms for limited periods. When connected to a properly matched motor, the drive can sustain an output of up to 5.0 kW, provided the supply provides 9.4 kVA of apparent power at the input terminals. The unit accepts a three-phase AC supply and typically draws 24.7 A rms under rated operating conditions. Control references arrive through an analog or pulse interface, and a sourcing output structure returns status signals to the controller. These current and power values help determine motor compatibility, circuit breaker capacity, and upstream transformer requirements for the installation.
The housing measures 100 mm wide, 205 mm high, and 220 mm deep, allowing side-by-side installation in control cabinets with sufficient mounting depth and ventilation clearance. It weighs 3.4 kg, which limits the mechanical load placed on a suitable DIN rail or backplate support. A built-in regenerative resistor dissipates energy returned from decelerating loads, helping prevent DC-bus overvoltage without requiring external regenerative hardware. The safety input connects directly to the safe torque off function because the model is supplied without a delay circuit, allowing immediate torque removal when the signal drops. Closed-loop speed regulation spans 1:5000, permitting slow indexing and rapid transfer operations on the same axis. Adequate spacing around the enclosure allows generated heat to escape while preserving access to the power, motor, control, and safety connections.
