Product Description:

The GADSE02LH24 is a servo amplifier from the G Sanmotion AC Servo Amplifiers series manufactured by Sanyo Denki. Serving as the power and control interface between a motion controller and a 400 W Sanmotion G servo motor, the unit supports the position, speed, and torque modes required for precise axis regulation in automated handling, packaging, and inspection equipment. It connects to industrial field networks and regulates motor current so that mechanisms follow commanded motion profiles without excessive overshoot or drift.

At the power stage, the amplifier delivers an instantaneous current capacity of 20 A while operating within the low-voltage 100 VAC class, making it suitable for compact machinery without higher-voltage supply rails. The switching bridge uses an IGBT sinusoidal PWM topology to minimize current ripple and acoustic noise. Network connectivity is provided through EtherCAT, allowing microsecond-level synchronization among multiple drives on the same bus. During acceleration or sudden load changes, the unit can supply a peak current of 12.0 Arms, so cabinet conductors and protection devices must tolerate these short-term surges. The command processor supports a velocity control range of 1:5000, giving the controller precise authority from crawl speeds to rated motor speed while accepting single-phase mains input.

Continuous operating current is limited to 3.1 Arms, which establishes the thermal steady-state limit of the power stage and helps protect the motor insulation. The internal logic, fans, and gate drives draw up to 0.8 kVA from the mains, so transformers and circuit breakers should be sized for this demand. Dynamic response is supported by a frequency characteristic of 3500 Hz, enabling tight current control when load inertia reaches the permitted ratio of 10 times the motor inertia. Regenerated energy is routed to an external resistor with a minimum resistance of 17 Ω to keep the braking transistor within its dissipation limit. Safe Torque Off includes a delay circuit, ensuring that drive output is disabled within a predictable time window during an emergency stop.
