Product Description:
The GADSE01LH24 is an AC servo amplifier produced by Sanyo Denki in the G Sanmotion AC Servo Amplifiers series. Serving as a single-axis drive controller, it supplies regulated current to a matched servomotor and exchanges motion commands with higher-level controllers in automated machines. By modulating power devices in real time, the unit maintains precise torque and speed loops, allowing assembly stations, packaging equipment, and semiconductor tools to synchronize motor movement with sensor feedback.
The drive stage has an amplifier capacity of 10 A, while its continuous thermal limit is 1.2 Arms. Brief acceleration demands are supported by a 4.3 Arms peak output current, providing additional current above the nominal value when the connected motor accelerates. The logic section draws only 0.5 Arms of control-circuit current, allowing the control power supply to remain compact. Overall demand on the mains is limited by a 0.4 kVA power supply capacity. Current shaping is performed by an IGBT sinusoidal PWM control system that reduces motor torque ripple. An external regenerative resistor must be connected to dissipate braking energy, and safe torque off protection is provided with a delay circuit. The external resistor must provide at least 25 Ω of resistance to keep the drive within its thermal limits.
Motion commands reach the amplifier through an EtherCAT single-axis interface that supports distributed clocks for sub-microsecond synchronization. When paired with a suitable servomotor, the unit can deliver up to 200 W of motor output, making it suitable for small actuators on pick-and-place heads or indexing tables. Installation is permitted at altitudes up to 2000 m without changing the stated ratings. The housing is 40 mm wide, 160 mm high, and 130 mm deep, allowing two units to be installed side by side within 100 mm of rail space. Despite its metal chassis, the amplifier has a mass of only 0.80 kg, which limits the load placed on the enclosure and mounting rail.
