Product Description:
The GADSA15AH24 servo amplifier is built by Sanyo Denki for the G Sanmotion AC Servo Amplifiers series. As a drive stage for permanent-magnet servo motors, it converts fixed mains power into regulated current for position, speed, or torque control commanded by a motion controller. Within an automated production line, the unit supplies dynamic motor power and processes feedback so that pick-and-place heads, indexing tables, or feed rolls can follow precise electronic motion profiles. This combination allows the amplifier to control rotary or linear servo axes that require responsive acceleration and accurate movement under changing loads.
The amplifier accepts a three-phase AC input, and its power section is rated at 13 kVA, allowing the inverter to supply enough energy for midsize rotary and linear axes. During rapid acceleration, the insulated-gate bipolar transistors can deliver up to 83.0 Arms to the motor windings. Continuous operation is supported at up to 34.0 Arms, helping the amplifier maintain motor torque during sustained production cycles without exceeding its current rating. When paired with a compatible motor and feedback device, the amplifier supports a mechanical output of up to 7.0 kW. The internal bus capacitors and protection network are suitable for Overvoltage Category III installations, allowing the drive to operate in distribution areas that may experience building-level electrical transients.
Real-time motion commands travel through the EtherCAT interface, permitting deterministic synchronization with higher-level controllers and other motion axes. The amplifier weighs 4.2 kg, and its built-in tray-style structure allows direct panel insertion without additional mounting brackets. Excess kinetic energy generated during motor deceleration is returned to the DC bus. When regenerated power exceeds 120 W, the dynamic brake diverts the energy through an external resistor bank with a minimum resistance of 6 Ω to prevent excessive transistor dissipation and resistor heating. The IGBT-based sinusoidal pulse-width modulation control system regulates current to the motor windings, supporting smooth torque production and accurate responses to changing speed or position commands.
