Internal Design and Servo Control

This servo amplifier uses a single IGBT module for motor drive. A DSP executes vector control algorithms at 16 kHz switching frequency. The GE A02B-0168-B012 accepts velocity and torque commands via the serial servo bus. Three current sensors provide real-time feedback for precise torque regulation. Two 1500 µF capacitors store energy for peak power demands. Consequently, this amplifier delivers smooth motion for single-axis applications.

Installation and Wiring Guide

First, mount this amplifier vertically inside a ventilated control cabinet. Next, connect 3-phase AC power to the L1, L2, and L3 terminals. Then, wire the servo motor cables to U, V, and W output terminals. Connect the encoder feedback cable to the CN2 port securely. Use shielded cables for all encoder and control signal wiring. The amplifier requires at least 100 mm clearance for proper air circulation. Four LED indicators show power, ready, run, and fault status. This amplifier works with GE Fanuc servo motors and CNC controllers. Always install an external circuit breaker for overcurrent protection.
