Internal Product Review
The GADSE03LH24 is a Sanyo Denki G Sanmotion AC servo amplifier with an EtherCAT interface and 30 A amplifier capacity. A 5.2 Arms continuous output current paired with 16.3 Arms peak output current gives this unit strong dynamic control for demanding motion applications. A 3500 Hz frequency characteristic stands out as a key advantage for fast, precise servo response.

Product Description:
The GADSE03LH24 is a compact AC servo amplifier developed by Sanyo Denki within the G Sanmotion AC Servo Amplifiers series. The unit serves as the power-conversion element that links a motion controller to a matched servomotor, providing the regulated current loops necessary for precise position and speed control in industrial automation cells. Designed for cabinet installation, it accepts a single-phase mains supply, monitors motor feedback, and issues high-frequency drive pulses that synchronize mechanical movement with programmed trajectories.
The power stage has an amplifier capacity of 30 A, delivering a continuous output of 5.2 Arms and short-duration bursts of up to 16.3 Arms when rapid acceleration is required. Line-side current draw is limited to 7.0 Arms by the single-phase input topology, while a separate 0.3 Arms control supply powers the logic section. Command and diagnostic data are exchanged over the EtherCAT interface. The internal current loop has a frequency response of 3500 Hz, allowing it to track reference changes while minimizing servo lag. A built-in STO delay circuit disconnects the drive signals after a set interval, supporting functional safety stops without mechanical relays. The available current output supports medium-frame Sanmotion motors used on pick-and-place axes and high-speed conveyors.
The amplifier requires a power supply capacity of 2.4 kVA. An external regeneration module channels excess braking energy through a resistor bank rated at 60 W with a resistance of 10 Ω, helping prevent DC-bus overvoltage during fast deceleration cycles. The housing withstands vibration levels of 6 m/s² and shocks of up to 20 m/s², allowing installation on mobile or vertically oriented assemblies. With an amplifier mass of 1.50 kg, the unit can be mounted on lightweight equipment panels without adding excessive load.
