Product Description:

The GADSA03AA22 servo amplifier is built by Sanyo Denki for the G Sanmotion AC Servo Amplifiers series. The unit conditions three-phase bus power and high-resolution command signals so that a connected motor receives precise current and voltage waveforms. By performing this conversion inside a compact panel-mount housing, it enables indexing tables, electronic cams, and other automation axes to maintain repeatable position, speed, and torque profiles under changing mechanical loads.

The power stage is rated for an amplifier capacity of 30 A, while the driver can deliver a continuous output of 5.2 Arms to the motor windings. For quick accelerations, it supports a peak output of 16.3 Arms; a 0.3 Arms control input channel modulates these currents according to velocity or position error. Mains supply requirements reach 2.4 kVA, and the internal control loop maintains amplitude accuracy over frequency components up to 3500 Hz. When paired with an appropriate encoder, the amplifier can produce a rated motor output of 1.5 kW from the connected servo motor without exceeding thermal limits.

Energy generated during deceleration is processed by built-in regenerative and dynamic brake circuits that dissipate excess power through an internal resistor rated at 60 W. That braking element provides 10 Ω of resistance, which is also the minimum resistance permitted for an external resistor added for higher duty cycles. The drive maintains speed linearity across a velocity control span of 1:5000 and remains stable with loads up to ten times the rotor inertia specified for the motor. It resists vibration levels of 6 m/s² and tolerates shocks of 20 m/s², allowing stable cabinet installation in stamping lines, pick-and-place gantries, and other high-impact machinery.
