Product Description:
The GADSA07AH24 is a servo amplifier from Sanyo Denki, supplied under the G Sanmotion AC Servo Amplifiers series. Designed to drive matched AC servo motors, the unit converts fixed-frequency input power into controlled three-phase output power that regulates torque, speed, and position in automated machinery. By combining current regulation with high-bandwidth velocity loops, it forms the interface between motion controllers and rotary or linear actuators in assembly cells, packaging lines, and semiconductor tools.
Its rated amplifier capacity of 75 A indicates the maximum instantaneous current the power stage can deliver before protective limiting occurs. During steady operation, the drive supplies a continuous output of 18.0 Arms, ensuring thermal stability for motors sized to its class. Short acceleration bursts are supported by a peak capability of 45.5 Arms, providing headroom for rapid indexing without requiring an oversized power supply. Current modulation is executed by an IGBT-based sinusoidal PWM control system, which produces low harmonic distortion and precise torque linearity. With a programmable velocity control range of 1:5000, the amplifier can maintain fine speed resolution from creep rates up to the rated base speed. The servo can tolerate load inertia up to ten times the rotor inertia without oscillation, simplifying mechanical tuning.
The drive pairs with motors rated up to 3.5 kW, so a single axis can handle medium-capacity conveyors, pick-and-place heads, or indexing tables. Line-side requirements call for a 7.1 kVA supply, allowing appropriate breaker and wiring selection for Category III industrial feeders. During deceleration, an internal brake circuit routes regenerative energy into a 6 Ω resistor, limiting the rise in DC-bus voltage and protecting the semiconductors. Operation on the factory floor is supported by a shock tolerance of 20 m/s² and a vibration tolerance of 6 m/s². The unit has a mass of 2.4 kg, which reduces panel loading when multiple amplifiers are rail-mounted in a multi-axis rack.
